What a betting system actually costs a New Zealand punter
Available in US
A betting system is not a shortcut to profit. It is a structure for placing bets, a plan for sizing stakes and a way of reading markets. What every system shares, whether it is a flat-stake routine, a chase progression, a Kelly-style sizing rule or an arbitrage hunt across two firms, is that it operates on prices set by a bookmaker. Those prices already contain a margin. The system decides which bets you take and how much you stake; it does not decide what the bookmaker keeps. That distinction is the whole subject of this page, and it is the reason a system that looks disciplined on paper can still bleed money month after month.
New Zealand sits in an unusual position. Since 28 June 2025, when section 74AAA of the Racing Industry Act 2020 took effect, TAB NZ and its sister brand Betcha are the only operators allowed to take online sports and racing bets from people in this country. Every other brand a New Zealand punter can name, every “best odds” offer, every boosted multi, sits outside that monopoly. The Department of Internal Affairs treats overseas firms offering these bets as breaking New Zealand law. The law targets the operator, not the punter. No published penalty for a player was found, but no New Zealand complaints route, no harm-minimisation framework and no regulator oversight reaches those firms either. Choosing a system starts with choosing where you place it, and only one set of doors in New Zealand opens lawfully.
This page covers what a betting system is, what it can and cannot do, what the law allows and forbids, where responsible gambling tools sit in the New Zealand market, and how the ten brands a New Zealand reader is most likely to compare stack up. The angle throughout is cost: what the system takes from the punter’s wallet, what the bookmaker’s margin takes from every bet, and what an offshore book takes from the protections a New Zealand bettor otherwise possesses.

How a betting system works in plain terms
A “system” sounds technical, but the core idea is simple. You pick a rule for selecting bets and a rule for sizing stakes, then you apply both consistently. The most common structures fall into a handful of families, and each one makes a different promise.
Flat staking means you bet the same dollar amount on every selection, regardless of the odds or your confidence. The upside is predictability: a losing streak hurts in a known way, and the maths of your edge, if you have one, stays stable. The downside is that flat staking does not adapt to anything, so a bettor with a real edge earns the same per unit of edge as one chasing a hunch.
Progression staking changes the stake based on prior results. A positive progression raises the stake after a win, hoping a hot run compounds. A negative progression, the “chase” system, raises the stake after a loss to recover the loss and book a small profit on the next win. The arithmetic of the chase looks tidy on paper, and that tidiness is the trap. Each step requires a larger stake than the last, the bookmaker’s maximum stake eventually caps the sequence, and the first loss at the cap wipes the cumulative stake and then some. A chase system is best read as a way to rearrange how losses are paid, not as a way to avoid them.
Value staking, often called Kelly staking in its simplest form, sizes the bet to the perceived edge: bigger stake when you believe the odds are wrong by more, smaller stake when you believe the edge is thin. The promise is that edge compounds proportionally. The catch is that estimating edge honestly is harder than estimating odds, and an overconfident bettor overstakes into a losing streak.
Arbitrage betting scans two or more bookmakers for prices that combine to a locked-in return regardless of outcome. The opportunity exists because bookmakers disagree, and the punter’s role is mechanical: back every outcome, lock in a small percentage profit. The mechanical promise is real when the prices hold; the practical cost is the account restrictions bookmakers place on customers who only ever bet arbs, the time spent finding the prices before they move, and the question of whether the bets were lawfully placed in the punter’s jurisdiction.
None of these systems alters the bookmaker’s margin. That margin is built into every price before the punter arrives, and it is why a system can be perfectly executed and still lose over time. The section on margins below shows how the same stake can return more or less depending purely on which side of the margin the price sits.
What a system can do is impose discipline on a process most bettors run by feel. That is real. What it cannot do is invent an edge that the underlying market does not contain. The punter’s job is to be honest about which is which.
Risk-free systems and what the marketing actually means
The phrase “risk-free betting system” appears on affiliate pages and in promotional emails. It has no standard definition. Sometimes it refers to matched betting, where a back bet at one bookmaker is hedged with a lay bet at an exchange so the return is roughly the same regardless of outcome. Sometimes it refers to a free bet that returns its winnings (not its stake) when it lands, with the stake written off as the “cost” of the offer. Sometimes it is simply a label stuck on a system that, like every system, can still lose.
The honest reading is that no system is risk-free in the sense the marketing uses the word. A free bet that does not return its stake is a stake the punter has already given up before the race starts. An arbitrage that requires two accounts, a price hold and simultaneous placement can fail at any of those steps. A “risk-free” label is the bookmaker’s framing, and the bookmaker has a margin to protect.
The legal landscape: who may take your bet
The Racing Industry Act 2020 and section 74AAA
New Zealand law changed materially in 2025. The Racing Industry Amendment Act 2025 inserted section 74AAA into the Racing Industry Act 2020. The section took effect on 28 June 2025 and states that no person other than TAB NZ may offer racing betting, sports betting or other racing or sports betting to a person in New Zealand, regardless of where that person is resident or incorporated. The Department of Internal Affairs told providers serving New Zealand customers to withdraw with immediate effect.
There is no licence register for bookmakers, because there is no licence to apply for. TAB NZ holds the only lawful position. The two online brands that take bets under that position are TAB and Betcha. They are not competitors; they are two faces of the same operator group.
What TAB and Betcha actually are
TAB NZ holds the monopoly. Its retail brand is TAB, with outlets around the country and the tab.co.nz platform online. Betcha is TAB NZ’s online-only sister brand, positioned for a younger audience with features like Multi Builder, a Bet Social feed and a Playbook with tips. Both run on the TAB NZ betting engine and both answer to the same operator.
The running of the TAB business sits with Entain under a 25-year agreement signed in 2023. Entain and TAB NZ split gross profits 50/50, with at least $150 million a year flowing to TAB NZ for the first five years. Entain also pledged a one-off $100 million payment to the racing sector when the deal closed. The partnership explains the scale of the platform but does not change who the lawful operator is: TAB NZ.
What the offshore brands are not
Every other brand a New Zealand punter encounters is an offshore brand. Some hold licences from Curaçao, Anjouan, the Tobique Gaming Commission, the Union of the Comoros or Costa Rica. None of those licences authorise taking bets from New Zealand residents under section 74AAA. The licences are real in the sense that the holder is registered somewhere, and they are irrelevant in the sense that the holder has no right to serve a New Zealand customer.
The Department of Internal Affairs is blunt about the risks. Offshore operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. A New Zealand punter who bets with one of these firms has no regulator to complain to, no harm-minimisation framework looking after them and no New Zealand law behind the bet. The punt itself is not a criminal offence. Section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing such a bet. The framing the law draws is deliberate: the operator is the target, the punter is the exposed party.
What that does to the system question
If a New Zealand punter uses a system on TAB or Betcha, the bet is lawful, the protections apply and the problem-gambling levy TAB pays funds harm minimisation in New Zealand. If a New Zealand punter uses the same system on an offshore brand, the bet is unlawful for the operator to take, the protections do not apply, and the punter carries the credit, payout and complaint risks alone. The system does not change; the choice of bookmaker does. That is the lens this page applies throughout.
Safer gambling and the New Zealand framework
The tools TAB NZ provides
TAB NZ lists deposit limits, time-outs and self-exclusion in its app. A punter who sets a deposit limit at the start of a session cannot blow past it without raising the limit, and raising a limit is a deliberate act rather than an impulse. A time-out is a short cooling-off period, days or weeks, in which which the account is locked. Self-exclusion is the longer lever, a six-month or longer block that prevents the punter from opening a new account under the same identity.
A TAB NZ self-exclusion applies across both TAB NZ brands. Betcha is not a separate door back into betting. An exclusion on TAB covers Betcha and vice versa.
The age for TAB NZ betting is 18. Land-based casinos are 20. The two ages are easy to confuse in casual conversation and they must not be merged. Betting under 18 is an offence under section 89 of the Racing Industry Act 2020.
The help that sits behind the tools
The free Gambling Helpline is 0800 654 655, with a text line at 8006. Safer Gambling Aotearoa is the public-facing body for gambling harm minimisation. TAB NZ pays a Problem Gambling Levy of 0.74% of its betting revenue, in force from 1 July 2025 to 30 June 2028, and the levy funds treatment and prevention services. A punter who finds their system running away from them has both a tool inside the app and a phone line outside it.
There is no single national online-betting exclusion register in New Zealand. The exclusion framework the Online Casino Gambling Act 2026 introduces applies to online casinos, not to sports and racing betting. A TAB NZ self-exclusion is a TAB NZ exclusion, and it is the lever a punter has at this stage.
Offshore brands and harm minimisation
An offshore brand is not subject to New Zealand harm-minimisation rules. The deposit limit, time-out and self-exclusion framework are operator-level features, and some offshore brands offer them, but the rules, the regulator and the funding of help services are the brand’s own. If a punter has set a self-exclusion at TAB NZ and then opens an offshore account to keep betting, the offshore account is not bound by the exclusion. The tool only works on the operator that holds the exclusion. That is part of why the monopoly matters for harm minimisation, not just for tax and orderly markets.
Strategies, predictions and what the punters actually do
The 2-6 system and its cousins
The “2-6 system” is a label that appears in New Zealand punter forums and a handful of affiliate pages. It refers to a staking progression: stake two units on the first bet, six on the second, then either reset or continue a further progression depending on the variant. The number of variants is the first clue: when a system has many versions, none of them has won the argument about which is best.
The progression logic is the second clue. Raising the stake after a loss increases the amount at risk on each subsequent bet. The bookmaker’s stake limit is the ceiling the progression cannot exceed. A punter who hits the ceiling before the recovery bet arrives has lost more than the system promised to recover. The arithmetic does not work without a ceiling the punter can afford to lose twice, which is not the same as a ceiling the punter can afford to lose once.
Accumulator systems and the multi market
Accumulator, or multi, betting is not a system in the staking sense. It is a market choice. The punter combines several legs into one bet, the odds multiply, and every leg must win for the bet to pay out. The bookmaker’s margin compounds across legs: each leg carries its own margin, and the combined margin is higher than the margin on any single leg. A 1.90 / 1.90 / 1.90 three-leg multi does not pay 4.51 times the effective odds of the underlying selections; it pays less, with the difference being the compounded margin.
Betcha’s Multi Builder is a tool for constructing multis, and it offers Same Game Multis where the legs come from one event. The tool is honest about what it is. It does not change the compounded margin. It does not make the legs easier to land. What it does is speed up the construction, and speed is useful when the punter wants to react to team news before the market does.
The accumulator insurance some brands promote, where a stake is returned if one leg lets the multi down, is a partial offset to the compounded margin, not a refund. The maths work out roughly to a single-leg free bet of equivalent value. The marketing calls it insurance. The ledger calls it a discount on a discount.
Bankroll management and staking discipline
Bankroll management is the least glamorous part of betting systems and the most useful. The punter sets a bankroll, a fixed sum reserved for betting, and stakes no more than a set percentage of it on any one bet. A common starting rule is one to two per cent of bankroll per bet, which means even a long losing streak does not exhaust the bankroll before the punter has time to reassess.
The discipline is not in the percentage. The discipline is in not raising the percentage after a win, when the bankroll feels flush, or after a loss, when the bankroll feels like a problem to be solved. A punter who sticks to the percentage through both conditions is doing what most systems try to do by formula.
Back-lay, arbitrage and the matched-bet route
Back-lay betting pairs a back bet at a bookmaker with a lay bet at a betting exchange, locking in a position that pays roughly the same whatever the outcome. The matched-bet system uses free bet offers at bookmakers as the back side and an exchange lay as the hedge, extracting a small guaranteed return from the offer. The system is real, and the returns are mechanical when the prices hold and the bets are placed.
Three conditions make the system hard to run at scale. The bookmaker restricts or closes accounts that only ever bet matched offers. The exchange charges commission on lay bets, eating into the locked-in margin. And the punter’s jurisdiction matters: a back bet at an offshore book may be unlawful for the operator to take from a New Zealand resident under section 74AAA. The mechanical promise of the system does not change the legal frame around it.
What a prediction system can and cannot do
A prediction system is a model, formal or informal, that picks winners. The model can be a checklist of form factors, a power ranking, a regression on past results or a tipster’s gut feel. The model’s value is measured in closing-line value: did it pick prices that were higher than the market’s closing price, and did it do so often enough to clear the bookmaker’s margin? Most models do not. The honest question for a punter evaluating a tipster is not how many winners the tipster had last week; it is whether the tipster’s prices beat the market over hundreds of bets. That data is rarely published, which is itself the answer.
The bookmaker’s margin and what it costs
What the margin actually is
The bookmaker’s margin is the cut the bookmaker keeps from every unit wagered on a market. It is the difference between the true odds and the odds offered, and it is built into the price before the punter places the bet.
For a two-way market at decimal odds of 1.90 on each side, the payout share is 1 divided by the sum of the inverse odds. That is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90), or 1 ÷ (0.5263 + 0.5263), which is 1 ÷ 1.0526. The payout share comes to roughly 0.9500, meaning the market returns about 95 cents of every dollar wagered across both outcomes. The margin is the remainder: about 5%.
The 5% is what the bookmaker keeps of every dollar bet on this market, on average, before any other cost. It is also the average amount the punter loses per dollar wagered, again before any other cost. The same stake, the same bettor, the same outcome, but the punter starts 5 cents behind on the dollar from the moment the bet is placed.
Why a margin band matters more than a single figure
The 5% figure is the result for one illustrative market at one illustrative price. Real markets vary. A 1X2 market on a strong-favourite football match might carry a margin of 2% to 4% because the favourite-short bias in the pricing reduces the overround. An NBA spread market or a totals line typically runs 4% to 6% because the bookmaker balances the action on either side of the line. A horse racing tote pool runs a different margin entirely, with the takeout disclosed on the race card. The margin on a multi with three legs compounds, so the multi’s effective margin is higher than any single leg.
State a single margin and the punter treats it as universal. State the margin as a band tied to the market, and the punter has a working tool. The 5% band above belongs to the example of a balanced two-way market at 1.90 / 1.90; for a multi or a one-sided market, the figure sits higher.
What the margin means for the system
A punter running a flat-staking system at one unit per bet is, on average, losing the margin per unit to the bookmaker before the system contributes anything. The system contributes when the punter picks prices higher than the true odds. If the punter beats the closing line by enough to clear the margin, the system is positive. If the punter picks at the market or below the market, the system is negative on top of the margin, and no staking structure recovers that.
This is why margin sits at the centre of any cost analysis. The system is not free. The punter is paying for the right to place a bet, and the price of that right is the margin on the market.
A worked example for a two-way market at 1.90 / 1.90
Assume a balanced two-way market at decimal odds of 1.90 on each outcome. The payout share is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90), which is about 0.9500. The margin is 1 − 0.9500, which is about 5%. Stated as a band, the margin for this illustrative market sits at roughly 4.5% to 5.5%, with the exact figure depending on rounding and on whether the price held to the close. The band is the figure the punter works with: every dollar wagered across both outcomes returns about 95 cents on average, and every dollar wagered on one outcome, by a bettor without an edge, returns 95 cents minus the punter’s edge shortfall.
A worked example for a three-leg multi
Take three legs at 1.90 each. The fair combined odds are 1.90³, which is 6.859. A bookmaker offering the multi at, say, 6.40 has built a compounded margin into the price. The punter’s job is to compare the multi’s effective margin, calculated as 1 minus the reciprocal of the sum of inverse-decimal probabilities implied by each leg, to the margin of staking each leg separately. The compounded margin is always higher. The question for the punter is whether the convenience and the payout structure make the difference worth it for the bet being placed.
The ten brands a New Zealand punter compares
The comparison below covers the two brands a New Zealand punter can lawfully use, TAB and Betcha, and eight offshore brands a New Zealand punter is likely to encounter. The offshore brands are listed for reference. Each one is marked as not licensed in New Zealand. The ranking is a comparison on published terms, not a recommendation. The point of the comparison is not to send a New Zealand punter to an offshore brand; it is to show, on the same criteria, what those brands offer and what they do not.
The matters the table compares are chosen for the page’s angle. They are the brand, the New Zealand status, and what the operator’s own terms state on the matter the section that follows it covers. The remainder of this section develops each brand in turn, on the same matters the table opens, so the reader has both the snapshot and the detail.
Brand-by-brand: what each operator’s own terms state
TAB
TAB is one of two online brands of TAB NZ, the only lawful provider of online racing and sports betting in New Zealand. The platform covers horse and harness racing, rugby union and rugby league and other sports, with pre-match and live markets. The app lists deposit limits, time-outs and self-exclusion, with the free Gambling Helpline at 0800 654 655 and the text line at 8006 listed inside the safer-gambling section.
The app carries a 17+ age rating in the App Store while stating that the betting age is 18. The 17+ rating reflects the App Store’s age categories rather than the betting age; the punter who is 18 or over is the lawful user, and the App Store rating is a separate gate. Trackside live race streaming with in-app betting, racing form, Blackbook and Jockey Challenge tools, and a simplified wallet for deposits and withdrawals round out the platform.
The verdict on TAB is that it is the only lawful online option in New Zealand, with the regulator oversight, harm-minimisation tools and complaint framework that follow from the monopoly. The punter who bets only with TAB is betting inside the frame the law draws. The punter who wants a feature TAB does not have, in-play depth on a niche league for example, will not find it here.
Betcha
Betcha is the other online brand of TAB NZ, positioned for a younger audience. The platform runs on the same engine as TAB and is covered by the same self-exclusion framework.
Betcha’s distinguishing features are the social and tooling layers. Multi Builder builds multi bets, with a copy-trending-multis function and a live-leg tracker. A new multi-grid builds Same Game Multis. The daily Toolbox carries odds boosts and insurance tools for bets that do not land. The Bet Social section is a feed where punters chat, follow tipsters and share bets or pools. The Playbook offers tips and match analysis. The Multi Builder is real value when the punter wants to construct a multi from a single event; the social layers are value when the punter reads other punters’ selections with the same skepticism they read the tipster’s.
The verdict on Betcha is that it is TAB NZ’s social-facing brand, with the same legal standing as TAB and a feature set aimed at the multi-bet punter. The punter who enjoys multi construction and Same Game Multis gets a toolset the retail TAB does not match. The punter who wants a quieter, form-led platform gets less of that here.
Thunderpick
Thunderpick is owned and operated by Paloma Media B.V., a Curaçao company with company number 146988, and is licensed by the Curaçao Gaming Authority under licence number OGL/2024/677/0722. That licence authorises the brand to operate in Curaçao. It does not authorise the brand to take bets from a person in New Zealand under section 74AAA of the Racing Industry Act 2020.
The brand markets itself around crypto esports betting, which positions it for a different punter than the racing-and-rugby audience TAB serves. A New Zealand punter who opens an account does so without New Zealand regulator oversight, without a New Zealand complaints route, and without the harm-minimisation framework TAB provides. The Curaçao licence is real in the sense that Paloma Media B.V. is registered. It does not change the New Zealand position.
The verdict on Thunderpick is that it is an offshore brand, licensed in Curaçao, with no right to serve New Zealand residents.
FunBet
FunBet’s sportsbook offers odds on football, ice hockey, American football, basketball, volleyball, tennis, rugby and baseball, with live betting and a bookmaker described as open around the clock. The brand names no licence that applies in New Zealand.
The sports coverage is broader than the headline rugby-and-racing focus of TAB, which is part of why the brand appears in comparison pieces. The breadth is the marketing hook. The New Zealand position is the same as every other offshore brand on this list: not licensed here, no New Zealand complaints route, no New Zealand harm-minimisation framework.
The verdict on FunBet is that it offers a broad pre-match and live menu on paper. For a New Zealand punter, that menu sits behind a lawful-status gap the operator’s own terms do not close.
RoyalistPlay
RoyalistPlay is owned and operated by Novatrix SRL, a Costa Rica company with registration number 3-102-893958. The brand states that it holds e-gaming licence No. 0000002 from the Tobique Gaming Commission. That licence is real in the sense that Novatrix SRL holds it. It does not authorise the brand to take bets from a person in New Zealand.
The Tobique licence is one of several regulator names that appear on offshore brands without that regulator having any oversight reach into New Zealand. The cost of that gap is the same as for any other offshore brand: no New Zealand regulator, no New Zealand complaints route, no harm-minimisation framework.
The verdict on RoyalistPlay is that it holds a Tobique e-gaming licence but possesses no New Zealand standing.
Roobet
Roobet is a brand name of Raw Entertainment B.V., registration number 157205, based at Korporaalweg 10, Curaçao. The brand is licensed under Curaçao licence OGL/2024/687/0427. The Curaçao licence authorises operation in Curaçao. It does not authorise taking bets from a person in New Zealand under section 74AAA.
Roobet markets itself as a crypto casino and sports betting brand. The crypto angle is part of the brand’s draw for the punter who wants to fund an account outside the banking rails. The draw does not extend to New Zealand consumer safeguards, because none apply.
The verdict on Roobet is that this Curaçao-licensed firm lacks New Zealand standing.
Winz.io
Winz.io states in its footer that it holds licences delivered by Anjouan and Tobique. Neither Anjouan nor Tobique has any oversight reach into New Zealand, and neither licence authorises taking bets from a person in New Zealand under section 74AAA.
The Anjouan-Tobique combination is a common pairing on offshore brands, and the regulatory weight of the pair is what their respective jurisdictions make of them. The cost for the New Zealand punter is the same as for any other offshore brand on this list: no New Zealand regulator, no New Zealand complaints route, no New Zealand harm-minimisation framework.
The verdict on Winz.io is that it operates on Anjouan and Tobique licences without New Zealand standing.
LegendPlay
LegendPlay’s sportsbook has Sports, Live Betting and Virtual Sports sections, with football, tennis, basketball and ice hockey listed. The brand names an Anjouan Gaming Authority licence. That licence is real in the sense that the brand holds it.
The Anjouan licence is the same family as Winz.io’s Anjouan-Tobique pairing, and the New Zealand position is the same. The sports coverage is broader than TAB’s headline menu in spots, which is part of why the brand appears in comparison pieces. The breadth sits behind a lawful-status gap the operator’s own terms do not close.
The verdict on LegendPlay is that it holds an Anjouan licence but lacks New Zealand standing.
BillyBets
BillyBets runs a casino and a sportsbook under one account. The sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football, baseball, combat sports, esports, virtual sports and live betting. The brand offers three odds formats: decimal (2.00), American (+100) and fractional (1/1). The site runs on Android and iOS through the mobile-optimised platform. Support is available 24/7 through live chat and a help centre.
The terms set the minimum age at 18 and state that the company gives no assurance on the legality of gambling in the player’s own jurisdiction, leaving the check to the player. That phrasing is the operator telling the punter, in writing, that the punter is on their own. A New Zealand punter who opens an account is not covered by any New Zealand regulator, and the operator’s own terms confirm it.
The verdict on BillyBets is that it offers broad sports coverage with three odds formats and 24/7 support. The brand’s own terms tell the New Zealand punter, plainly, that the legality check is the punter’s problem. The exposure is the same as for the rest of the offshore list.
BetNinja
BetNinja states that it is licensed to conduct online gaming operations by the Union of the Comoros. That licence authorises operation in the Union of the Comoros.
The Comoros licence is the same family as several other entries on this list, and the New Zealand position is the same. The brand’s coverage is the offer; the lawful-status gap is the cost.
The verdict on BetNinja is that it holds a Union of the Comoros licence but lacks New Zealand standing.
The comparison operators at a glance
The table below lines up the ten brands on the matters the page covers. The New Zealand status column reflects section 74AAA of the Racing Industry Act 2020: TAB and Betcha are the two online brands of TAB NZ, the only lawful provider, and the other eight are not licensed in New Zealand. The third column summarises what the operator’s own terms state on the key the brand-by-brand section covers above; cells where the operator names no licence that applies in New Zealand are marked accordingly.
| Brand | New Zealand status | What the operator’s own terms state |
|---|---|---|
| TAB | TAB NZ brand, the only lawful provider | 18+ to bet; deposit limits, time-outs and self-exclusion in app; Gambling Helpline 0800 654 655 and text 8006 listed |
| Betcha | TAB NZ brand, the only lawful provider | Multi Builder, Same Game Multis, daily Toolbox, Bet Social, Playbook; 18+ to bet |
| Thunderpick | Not licensed in New Zealand | Curaçao licence OGL/2024/677/0722, holder Paloma Media B.V. |
| FunBet | Not licensed in New Zealand | No licence that applies in New Zealand named in the operator’s own terms |
| RoyalistPlay | Not licensed in New Zealand | Tobique e-gaming licence No. 0000002, holder Novatrix SRL |
| Roobet | Not licensed in New Zealand | Curaçao licence OGL/2024/687/0427, holder Raw Entertainment B.V. |
| Winz.io | Not licensed in New Zealand | Anjouan and Tobique licences named in the operator’s footer |
| LegendPlay | Not licensed in New Zealand | Anjouan Gaming Authority licence named in the operator’s terms |
| BillyBets | Not licensed in New Zealand | Terms place the legality check on the player; 18+ to bet |
| BetNinja | Not licensed in New Zealand | Union of the Comoros licence named in the operator’s own terms |
The pattern is the same down the right-hand column. The two TAB NZ brands carry the regulator, harm-minimisation framework and complaint route that come with the monopoly. The eight offshore brands each hold a licence somewhere; none of those licences extend to New Zealand, and the operator’s own terms, where they address the question at all, place the legality check on the player. The breadth of sports coverage some offshore brands advertise does not change the lawful-status gap.
Working the numbers a punter actually uses
What a winning bet pays back
A winning single bet returns stake multiplied by the odds. A bet of $10 at 2.10 returns $21, with $10 of that being the original stake and $11 being the profit. A combination bet multiplies the odds of the legs into one price, so three legs at 1.80, 2.00 and 2.50 multiply to a combined price of 9.00, and a $10 stake at that combined price returns $90 if all three legs win.
The payout is what a winning bet pays back. It is not a prediction of whether the bet will win. A bookmaker offering 9.00 on a three-leg multi has built a compounded margin into the combined price, so the combined price is lower than the fair combined odds of 9.00 the multiplication above produces. The punter’s edge, if any, is the difference between the punter’s estimate of fair odds and the bookmaker’s offered odds, less the compounded margin.
What a free bet is worth
A free bet whose stake is not paid back with a win has a value equal to the free-bet amount multiplied by the odds minus one, divided by the odds, multiplied by the payout share of the market. For a $10 free bet at odds of 3.00 on a market with a payout share of 0.95, the value is $10 × (3.00 − 1) ÷ 3.00 × 0.95, which is $10 × 0.667 × 0.95, or about $6.33. That is the average value of the free bet over many uses, not what any single use of the free bet pays back.
A free bet whose stake is paid back with a win has a different value calculation, and the operator’s terms state which kind the punter holds. “Risk-free” marketing is not the same as a stake-paid-back free bet. The punter who wants to know the value reads the terms.
How much betting a bonus takes
A bonus with a wagering requirement has a turnover, which is the bonus base multiplied by the wagering factor. For a $100 bonus with a 5x wagering factor on the bonus, the turnover is $500. At a $10 stake per bet, that is 50 bets. Only bets at or above the minimum price the terms name count toward the turnover, and the minimum price is a real filter: bets below it do not count.
The arithmetic is a calculation, not a guarantee. The punter who clears the bonus over 50 qualifying bets has cleared the wagering requirement, and the bonus, less any winnings cap the terms name, is what remains. The punter who runs out of bonus or time before clearing has lost the bonus and the qualifying bets.
What clearing the offer costs on average
The expected cost of clearing an offer is the required turnover multiplied by the margin of the market the punter bets on. For a $500 turnover at a 5% margin, the expected cost is $25. The expected cost is what the offer costs on average over many uses, not what any single punter pays. A punter who has an edge that beats the margin clears the offer at a profit; a punter without the edge pays the expected cost.
The expected cost is the line a punter calculates before claiming a bonus. A $100 bonus that costs $25 to clear on average is worth $75 in expected terms, before any other condition. A $100 bonus that costs $80 to clear on average, because the margin is higher or the wagering is heavier, is worth $20 in expected terms. A bonus whose expected cost is higher than its face value is a marketing loss dressed up as a giveaway.
Greyhound racing and what is changing
Greyhound racing in New Zealand is closing in stages from 1 August 2026. From that date, offshore operators may not take bets on greyhound races either, because greyhound racing is part of the racing betting that section 74AAA covers. A punter whose system leans on greyhound markets needs to redirect the bet volume before the closure bites, or accept that the volume is gone.
The closure is part of the wider orderly-market push the Racing Industry Amendment Act 2025 embodied. It does not change the monopoly; it tightens the scope of what falls inside the monopoly. A punter reading the law in plain English sees that New Zealand has decided greyhound racing is a sport the country no longer runs, and the betting on it is being wound down with the sport.
Tax, duty and what Inland Revenue sees
For the punter, recreational gambling winnings are generally not taxable, and prize money from TAB horse, dog and trotting races is not taxable. A person who bets as a business is a different case, and the honest summary is that Inland Revenue’s guidance and an accountant are the sources to consult for that case.
For the operator, TAB NZ pays the Problem Gambling Levy of 0.74%. Offshore operators supplying New Zealand residents pay online gambling duty of 12% of profits since 1 July 2024, rising to 16% from 1 January 2027. The duty is payable by an operator serving New Zealand residents, but the duty being payable does not make the offer lawful. A bookmaker paying duty in New Zealand is not the same as a bookmaker licensed in New Zealand, and the two facts do not cancel each other.
The point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026. The change reflects the shift from taxing the offshore firm to running the monopoly tighter through section 74AAA.
Advertising, affiliates and what the code says
The Advertising Standards Authority’s Gambling Advertising Code applies to betting advertisements. Ads must not target children under 14 or young people aged 14 to under 18, judged by context, appeal and expected audience. Where accurate audience data exists, 25% or more of the audience counts as significant. Ads must not encourage harm and must be truthful, with terms available. There is no New Zealand equivalent of a “whistle-to-whistle” ban for betting.
How the Department of Internal Affairs treats betting affiliates is not established. The Department of Internal Affairs reads the prohibition in section 74AAA as covering promoting or taking bets for another operator, but the practical reach of that reading into affiliate marketing is not pinned down. A punter who sees an affiliate promoting an offshore brand is seeing a marketing channel whose relationship to the monopoly is not defined.
How to read the comparison
The two paths a New Zealand punter can walk are clear. The TAB NZ path runs through TAB and Betcha, with the regulator, the harm-minimisation tools and the complaint framework that come with the monopoly. The offshore path runs through one of the eight brands covered above, with no New Zealand regulator, no New Zealand complaints route and no New Zealand harm-minimisation framework. The system the punter uses is the same on either path; the protections are not.
For the punter who chooses the TAB NZ path, the practical question is which of the two brands fits the punter’s habits. TAB is the retail-facing platform with form tools, racing depth and a quiet interface. Betcha is the social-facing platform with Multi Builder, Same Game Multis and a daily Toolbox. Both run on the same operator, both close to the same self-exclusion framework, and both answer to the same regulator.
For the punter who is considering the offshore path, the practical question is whether the marketing is worth the exposure. The breadth of sports coverage, the crypto funding, the multi-bet tooling and the daily boosts do not change the lawful-status gap. They do not give the punter a regulator to call when a payout does not arrive. They do not give the punter a harm-minimisation framework with New Zealand funding. They give the punter a price on a market, with no recourse if the price does not pay out as the terms promise.
The honest summary is that the choice is not between two bookmakers; it is between a framework with one lawful option and a set of firms outside that framework. The punter’s system runs on top of whichever framework is chosen.
Frequently asked questions
How does a betting system work?
A betting system is a rule for selecting bets and a rule for sizing stakes, applied consistently over time. Flat staking bets the same amount on every selection, progression staking adjusts the stake after wins or losses, value staking sizes the stake to the perceived edge, and bankroll management caps the stake as a percentage of a fixed bankroll. The system decides which bets you take and how much you stake; it does not decide the bookmaker’s margin, which sits inside every price before you arrive.
What is a chase system sports betting?
A chase system is a negative progression: the punter raises the stake after a loss to recover the loss and book a small profit on the next win. The arithmetic looks tidy on paper, but each step requires a larger stake than the last. The bookmaker’s maximum stake caps the sequence, and the first loss at the cap wipes the cumulative stake. A chase is a way to rearrange how losses are paid, not a way to avoid them.
Which bookmaker may lawfully take sports and racing bets in New Zealand?
TAB NZ, through its two online brands TAB and Betcha. Section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025, prohibits any other person from offering racing or sports betting to a person in New Zealand. The Department of Internal Affairs told providers serving New Zealand customers to withdraw with immediate effect. There is no licence register for bookmakers, because there is only one lawful provider.
How is the return on a bet worked out from the stake and the odds?
Return equals stake multiplied by the odds. A stake of $10 at decimal odds of 2.10 returns $21 in total, with $10 being the original stake and $11 being the profit. For a combination bet, the odds of the legs multiply into one price; three legs at 1.80, 2.00 and 2.50 combine to a price of 9.00, and a $10 stake returns $90 if all three legs win. The bookmaker’s compounded margin sits inside that combined price.
What is the bookmaker’s margin and how can it be seen in the odds?
The margin is the cut the bookmaker keeps from every unit wagered on a market. For a two-way market at decimal odds of 1.90 on each side, the payout share is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90), or about 0.95. The margin is 1 minus the payout share, or about 5%. The margin is what the bookmaker keeps of every dollar bet on the market, on average, before any other cost. The same arithmetic, applied to a multi with three legs, gives a higher compounded margin because each leg carries its own margin.
What does a player lose by betting with a bookmaker that has no New Zealand licence?
A player loses the regulator, the harm-minimisation framework and the complaint route that TAB NZ provides. The Department of Internal Affairs warns that offshore operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. The bet is not a criminal offence for the player under section 19(4) of the Gambling Act 2003, but no New Zealand regulator oversees the offshore bookmaker, and no New Zealand complaints route reaches it. The exposure sits with the player.
