18+ Only

A punter in New Zealand who wants to bet on basketball in 2026 walks into a market with one door. Two brands sit behind it. The other nine names you’ll find in a Google search sit somewhere else, and the difference between those two groups matters more than anything else on this page. From here it unfolds: who each brand suits, what a basketball price is actually made of, the bet types that move basketball markets, the tournaments worth watching through the year, the live betting and cash-out picture, what an app gives a punter and what an app takes away, and the responsible gambling framework that sits over the lot — in that order, because that’s how a Kiwi punter choosing where to play makes the decision.

The data on odds, products and licences below is current as of 31 October 2026 and has been checked against the New Zealand Department of Internal Affairs register and the Racing Industry Act 2020, as amended in 2025.

Staying in control: the harm-minimisation frame that sits over every bet

Basketball in New Zealand runs fast — four 12-minute NBA quarters, four 10-minute FIBA quarters, five-minute overtime periods — and the scoreboard barely sits still. That tempo is what makes live markets attractive, and it is also what makes the safeguards worth naming before a punter opens an account with anyone.

TAB NZ lists three tools inside its app: deposit limits, time-outs and self-exclusion. An exclusion set on one TAB NZ brand applies across both of them, because they are one operator under two names. The 18-or-over rule sits underneath all of it — the app store rating reads 17+ as a content floor, but betting itself is an 18+ activity under section 89 of the Racing Industry Act 2020, and the operator enforces it at account opening.

A free line sits beside the app: the Gambling Helpline on 0800 654 655, with text support on 8006. Safer Gambling Aotearoa is the public-facing body that backs it. TAB NZ funds both through a Problem Gambling Levy of 0.74% in force from 1 July 2025 to 30 June 2028 — a small, fixed contribution that buys a real complaints route and a regulator who can actually answer a phone.

None of this reaches an offshore operator. A Curaçao or Anjouan licence is a permission to operate from that jurisdiction; it does not extend a New Zealand complaints route, a New Zealand harm-minimisation framework, or any recourse through the Department of Internal Affairs. The Department told such providers to withdraw from New Zealand with immediate effect when the prohibition took force on 28 June 2025, and the law targets the operator. The player side is set out differently: section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. No published penalty for a player was found. So the framing the page takes is the honest one — TAB NZ and Betcha carry the New Zealand safeguards, an offshore brand carries its own house rules, and the choice between them is the bettor’s to make with their eyes open.

Two practical habits help regardless of where the bet lands. Set a deposit limit before the first deposit, not after a losing weekend. Read the app’s stake and payout limits, because TAB NZ sets its own caps and offshore books set theirs; neither is the same as the other, and neither is the same as the statutory maximum, because there isn’t one. The rest of this page is about choosing where to play — and the framework above is what makes that choice sensible.

Mobile and app: what each brand actually puts on the screen

The TAB NZ app — listed as “TAB – Racing & Sports Betting” on the New Zealand App Store, first released on 8 September 2014 — covers horse, harness and greyhound racing alongside rugby union, rugby league and other sports, with both pre-match and live markets. A 17+ age rating sits on the store listing, with the operator’s own rule of 18+ to bet. The app carries Trackside live race streaming with in-app betting, racing form, Blackbook and Jockey Challenge tools, and a simplified wallet for deposits and withdrawals. Basketball lives inside the wider sports list rather than as its own tab, and the same product surface — fixed-odds, Same Game Multi, live markets where they’re listed — applies to it.

Betcha, the second TAB NZ brand, launched on the New Zealand App Store on 6 August 2024, published by Entain New Zealand Limited. Its sportsbook covers horse, greyhound and harness racing plus rugby, NRL, MMA and UFC, NBA, NFL, tennis, cricket, football, motorsports and esports — a broader menu than the TAB app for some codes, and a clear basketball bet that is for NBA fixtures in particular. Both apps run under one TAB NZ wallet and one exclusion list, which is the practical upshot of the partnership.

A punter asking which app to install is asking the wrong question if they’re inside New Zealand, because both brands are TAB NZ. A more useful question: which surface suits the bet they want to place. TAB has the racing depth, the Trackside stream, the Jockey Challenge tools, and the long history. Betcha has the newer interface, the broader international sports menu, and the esports presence. Both apps run on iOS and Android, both support deposits and withdrawals inside the app, and both enforce the same harm-minimisation tools because they share a backend.

Three things a basketball punter needs to check on any app before placing a bet:

1. Whether live betting is listed for the specific NBA or FIBA fixture in question, because not every market on every game is offered in-play.
2. Whether the Same Game Multi product covers the player props they want to combine — points, rebounds, assists, three-pointers made — because the legs available change by event.
3. Whether the deposit and withdrawal methods match what the punter actually uses. TAB NZ publishes its own payment methods inside the app, and offshore brands publish theirs.

A last point worth making: a punter who wants to bet on basketball from a desktop rather than an app can do so, because TAB NZ’s website carries the same markets as the app under the same wallet. The mobile experience is the slicker one, which is why the apps dominate the discussion.

Live betting and cash out: the in-play picture

Basketball is built for live betting. Stoppages are short, scoring runs are visible within a possession, and the line moves in real time. The product that makes live betting more than a price-taker’s game is cash-out: the ability to close a bet before the event finishes, at a price the bookmaker offers rather than the price the market will clear at.

TAB NZ’s live markets sit inside both TAB and Betcha, and any specific restriction on in-play basketball markets is not established in statute — the Racing Industry Act 2020 leaves the question of which markets to list to the operator. The practical limit is what the app exposes on a given fixture, not what the law forbids.

The offshore shelf offers cash-out in a more uniform way. Thunderpick, RoyalistPlay, FunBet, BigClash and Spinbara each name cash-out as a feature in their own product copy, with varying depths of market coverage. Sportaza goes further — its terms allow cash out before the event or market is finalised, and its Bet Builder product voids the whole slip if one leg is void rather than treating the bet as a winner on the remaining selections. That is a real design choice, and a punter who builds player-prop multis needs to know it.

Two design patterns worth naming, because they shape a live-bet experience in ways that aren’t obvious from the marketing page:

• The void-leg treatment. Some books treat a void leg in a multi as a non-event — the bet continues on the remaining legs at reduced odds. Sportaza, by its own terms, voids the whole slip. The difference is real money on a Same Game Multi where one player is scratched before tip-off.
• The interval market. Sportaza lists interval markets in 1, 5, 10 or 15-minute ranges. That’s a niche product — useful for a punter who thinks the next five minutes of an NBA game will be one team’s, less useful for someone trading the full game.

The honest summary: TAB NZ and Betcha carry live basketball markets on the fixtures they list, with cash-out available on selected markets as the operator’s terms allow. The offshore shelf carries more in-play variety in some places and a more uniform cash-out story in others. A live-betting punter must match the brand to the market they want to trade, not the other way round.

Predictions and strategy: bankroll, forecast and the honest limits of both

Basketball betting tips, basketball predictions, basketball betting systems — the search volumes behind these phrases are large, and the result behind them is mixed. The clean version: a tip is a forecast of who wins or by how much, and a system is a rule that turns forecasts into stakes. Neither beats a bookmaker’s margin over a long enough run unless the forecasts carry information the price hasn’t already discounted, and a price already discounts the information most forecasts are made from.

What a basketball punter in New Zealand can actually do, regardless of where they bet:

• Use the public record. NBA box scores, team pace ratings, injury reports and rest-day flags are all public, all free, and all priced into the line by the time the market settles. The information edge is small, and the punter pays for it through the margin.
• Specialise on a niche. A punter who follows one team closely knows things the line hasn’t caught yet — a rotation change, a player returning from a minor injury, a coach’s tendency in back-to-backs. The edge, if any, comes from that depth, not from a system.
• Bet the spread, not the moneyline. Basketball lines are tighter than most codes, and the spread is where most of the price moves. A punter who thinks the favourite wins by more than the line is making a sharper call than one who simply picks the winner.
• Keep the stake small relative to the bank. A 1–2% stake on any single bet is the standard bankroll rule, because losing streaks in basketball are not rare — even the best NBA teams lose 30% of their games over a season, and a punter who bets a fixed unit on every game will see a 10-bet losing streak inside one.

The honest statement: no system in basketball betting beats the margin in expectation. A punter who bets profitably over a long run has either found a real information edge, or has been lucky, and the only way to know which is to keep records. The site does not predict winners and does not sell systems. The product of the sport is the bet, and the product of the bet is the price, and the price is what the rest of this page is about.

Bet types and odds: selections, staking and what a price actually means

A basketball bet has three shapes: the moneyline (who wins), the spread (by how much) and the total (how many points are scored). Inside each, the bookmaker lists a price in decimal form — $2.10 means a $10 stake returns $21, profit $11. The price reflects two things: the probability the bookmaker puts on each outcome, and the margin the bookmaker keeps.

The standard basketball market menu, as listed by an offshore bookmaker with broad coverage:

• 1X2 — home win, draw, away win. Draw at full time is rare in basketball but exists in some league formats.
• Double Chance — two of the three outcomes combined into one bet.
• Totals — over or under a line on combined points, typically around 210–230 for NBA and 150–170 for FIBA.
• Both teams to score — a yes/no on both teams clearing a threshold.
• Correct score — the exact final margin or scoreline.
• HT/FT — half-time result combined with full-time result.
• Handicap / spread — one team starts with a virtual points advantage or deficit.
• Player props — points, rebounds, assists, three-pointers, double-doubles, and Same Game Multis built from them.
• 3×3 basketball markets — a separate code with quarter-final, semi-final and final markets for FIBA 3×3 events.

A punter looking at a decimal price reads it as a probability: 1 ÷ price. A $2.10 price is 1 ÷ 2.10 = 47.6% implied probability. A $1.50 price is 66.7%. A $4.00 price is 25%. Two prices on the same event — $2.10 on team A and $1.80 on team B — imply 47.6% and 55.6% respectively, totalling 103.2%. The 3.2% gap is the bookmaker’s margin on the two-way market. That is the price of the bet the punter pays.

The same arithmetic on a three-way basketball market (home, draw, away) sums to slightly more than 100%, and the gap is again the margin. The margin is the bookmaker’s edge per unit bet, and a punter who bets on a 5% margin market loses 5% of every dollar staked over a long enough run, before any skill edge is layered on top. The closer the margin is to zero, the closer the punter is to a fair game.

The page carries one worked illustration of this arithmetic, because the rest of the page keeps coming back to it.

A two-way market at 1.90 / 1.90 — what the margin looks like

The margin formula treats the decimal odds as the bookmaker’s stated probabilities and asks what share of every dollar bet the book returns across all outcomes. For a two-way market with both sides priced at 1.90, the arithmetic is 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90) = 1 ÷ (0.5263 + 0.5263) = 1 ÷ 1.0526 = 0.95 — a 95% payout share. The margin, on the same arithmetic, is 1 − 0.95 = 0.05, or 5%. Every $100 bet on this market returns $95 across the two outcomes on average; the bookmaker keeps $5.

The honest framing of that number: a 5% margin is in the typical band for NBA and major FIBA fixtures at a sharp bookmaker. A 7% to 8% margin is typical for smaller leagues or props markets. A 3% margin is the kind of price a sharp punter chases, and a 10%+ margin is what a recreational bookmaker on a niche market charges. The margin is not a fee; it is built into the price, and the punter cannot opt out of it.

The same arithmetic explains why betting on the favourite looks safer than it is. A $1.30 price on a heavy favourite implies 76.9% probability and pays back $13 on a $10 stake; the punter wins often, but the price reflects the 23.1% the market puts on the upset, and that 23.1% comes up more often than a punter who bets every heavy favourite will like.

Sports and tournaments: where the basketball calendar lives

The basketball calendar runs year-round, but the fixtures that move the betting markets sit on a tighter schedule.

NBA season. The NBA regular season runs from late October to mid-April, with the play-in tournament and playoffs through May and June, and the Finals in June. Eight to ten games per night in the regular season is the volume, and the line moves on every one. Same Game Multis on player props are most active as the NBA season plays out, because the box-score data is richest and the bookmakers are most confident pricing it.

NBA preseason. Early October through late October, with limited minutes for stars. The line is thinner, the props are shallower, and the live market is less reliable. Most serious basketball punters sit out the preseason.

FIBA international windows. November, February and June/July windows for national-team competitions. The 3×3 basketball world tour runs alongside. Player prop markets on national-team basketball are narrower than NBA props, and the moneyline and handicap markets carry most of the volume.

EuroLeague and EuroCup. The top European club competition runs from October to May, with a Final Four in May. National-team leagues — Liga ACB, Lega Basket Serie A, the Greek league, the Turkish league — feed into it. Markets are typically less liquid than NBA, with higher margins as a consequence.

NBL (Australia and New Zealand). The Australian NBL runs from October to March, with the Breakers as the New Zealand team. Markets exist on NBL fixtures at most major bookmakers, but volume is lower than the NBA. The New Zealand NBL is a smaller competition; whether any major bookmaker lists it consistently is a question of operator policy.

3×3 basketball. Olympic since 2020, with a World Tour and World Cup. Markets are listed on 3×3 events by some bookmakers, with moneyline and quarter-final markets the typical offering.

College basketball. The NCAA season runs from November to April, with March Madness as the peak. Some bookmakers list college basketball markets more deeply than others. TAB NZ’s coverage of college basketball is narrower than its NBA coverage in the typical case.

A punter asking which tournaments to follow asks the bookmaker which markets they list, because the bookmaker’s market list is the answer to the question. TAB NZ’s app exposes its full basketball schedule; the offshore shelf varies by operator and by season. The schedule above is the shape of the calendar — the specific market list is what a punter checks in the app or the website before betting.

The ten brands, ranked by who each one suits

The page’s ranking here is a comparison, not a recommendation. TAB and Betcha are one operator under two names and they sit together; the eight foreign brands sit beside them for reference because New Zealand punters meet them, and each is rated by the same criteria.

The table is the shape of the shelf. The verdict below is who each brand suits in practice.

TAB — the lawful default for a New Zealand punter

TAB is the older of the two TAB NZ brands, and the one with the racing depth: horse, harness and greyhound racing inside the same app as the sportsbook, with Trackside live race streaming, racing form, Blackbook and Jockey Challenge tools, and a simplified wallet. Basketball sits inside the broader sports list — NBA and major European leagues, pre-match and live, with Same Game Multi on the bigger fixtures. The wallet, the deposit limits, the time-outs and the self-exclusion all run across both TAB and Betcha because they are one operator. The 18+ enforcement at account opening is the operator’s own, with a verified New Zealand address and ID. A punter asking for the lawful path with the New Zealand safeguards finds it at the TAB app, and the rest of this ranking is read against that choice.

Betcha — the second TAB NZ brand, with a broader international menu

Betcha launched on 6 August 2024 and runs the broader international sports menu: NBA, NFL, NRL, MMA and UFC, tennis, cricket, football, motorsports and esports, with horse, greyhound and harness racing alongside. For a basketball punter whose interest is the NBA specifically and who wants a newer interface than the TAB app, the Betcha app is the practical alternative inside the same TAB NZ account. The same exclusion list, the same deposit limits, the same harm-minimisation framework. The product is the same — same markets, same wallet, same backend — with a different front end.

Thunderpick — esports-first, basketball on the side

Thunderpick’s product is esports — CS2, League of Legends, Dota 2 and Valorant — with a sportsbook that lists cash-out and markets from the Champions League to the NFL. Basketball exists inside that sportsbook, but the depth and the volume are not the centre of the product. The Curaçao licence (OGL/2024/677/0722) gives the brand the right to operate from that jurisdiction; it does not give it the right to take bets from people in New Zealand. Choosing to use Thunderpick from New Zealand means stepping outside the regulated framework, and that is a choice a player makes alone.

RoyalistPlay — broad sports menu, basketball listed

RoyalistPlay’s sportsbook lists live betting, sports promotions, results and a schedule, with football, basketball, tennis, handball, ice hockey, volleyball and table tennis among the top sports, plus separate e-sports and Predictions sections. The Tobique Gaming Commission e-gaming licence gives the brand its operating permission; again, no right to take bets from people in New Zealand. For a basketball punter who wants a broad sports menu and is comfortable offshore, the brand exists; for a New Zealand punter, the lawful option sits with TAB NZ.

Golden Panda — sportsbook with virtual sports and esports

Golden Panda offers a Sports section with a sportsbook, esports and virtual sports, plus casino, live casino, crash games, rewards, cashback, a VIP Club, Golden Goals and Prediction Markets. The product is broader than basketball alone, and the brand names no licence that applies in New Zealand. A New Zealand punter using this brand is offshore and given the same framing as the others in this group.

FunBet — round-the-clock sportsbook with basketball listed

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 24/7. The brand names no licence that applies in New Zealand. The product is straightforward — a sportsbook with basketball listed, a live product, and the standard offshore welcome structure. Those wanting a 24/7 sportsbook and who are comfortable offshore find it here.

BigClash — pre-match, live and virtual sports

BigClash offers pre-match and live sports betting across international and local leagues, plus virtual sports and esports betting on FPS and MOBA titles. The Curaçao licence (8048/JAZ) gives the operating permission; no right to take bets from people in New Zealand. The product is the standard offshore sportsbook shape, with basketball inside the live and pre-match schedule and a virtual sports section on the side.

22Bet — deep market menu across events

22Bet lists over 30 market types per event — 1X2, Double Chance, totals, both teams to score, correct score and HT-FT — plus tennis game, set and handicap markets that signal a deep market-builder approach. The Curaçao licence (8048/JAZ, holder TechSolutions Group N.V.) gives the operating permission; no right to take bets from people in New Zealand. For a punter who wants a deep market menu and a wide event list, 22Bet is the operator in this group that goes furthest on markets; for a New Zealand punter, the lawful option is still TAB NZ.

Sportaza — the cash-out and Bet Builder specialist

Sportaza’s terms allow cash out before an event or market is finalised, with a Bet Builder that voids the whole slip if one leg is void rather than treating it as a winner on the remaining legs. Multiples, Asian lines and interval markets in 1, 5, 10 or 15-minute ranges add a niche depth on top of the standard basketball schedule. The Anjouan licence (ALSI-202606064-FI2) gives the operating permission; no right to take bets from people in New Zealand. A punter who trades in-play and builds player-prop multis will read the void-leg treatment as a real design point; staying with TAB NZ remains the lawful option.

Spinbara — the bonus-shelf brand

Spinbara’s English site advertises a first deposit bonus of 100% up to EUR 100 and a sport crypto welcome bonus of 100% up to 200 USDT, alongside a casino welcome bonus of 100% up to EUR 500 plus 200 free spins. The brand names no licence that applies in New Zealand. The product is the standard offshore sportsbook plus casino shape, with a heavier bonus shelf than some of the others in this group. For a New Zealand punter, the lawful path is still TAB NZ, and the offshore shelf is what it is.

Overview: what basketball betting in New Zealand looks like

Basketball betting in New Zealand is the NBA on a Tuesday night in November, the EuroLeague in February, the FIBA 3×3 World Tour in summer, and the NBL with the Breakers for the home audience. The product is the same as it is in any other market — moneyline, spread, total, player props, Same Game Multi, live betting, cash-out — but the supplier list is shorter than most.

TAB and Betcha are the two online brands of TAB NZ, run under a 25-year partnership signed with Entain in 2023 that gives Entain a 50/50 share of gross profits, with at least $150m a year going to TAB NZ for the first five years, and Entain pledged a one-off $100m payment to the racing sector. The arrangement puts the operator behind a single regulated entity, with the Department of Internal Affairs as the regulator under the Gambling Act 2003 and the Racing Industry Act 2020 as the framework. The Racing Industry Amendment Act 2025, in force from 28 June 2025, made the position explicit: no person other than TAB NZ may offer racing or sports betting to a person in New Zealand, regardless of where that person is resident or incorporated.

The practical shape of that rule is the shape of this page. TAB NZ publishes its own betting rules and its own market list; the list is the answer to which basketball markets are offered to a New Zealand punter. The offshore shelf sits beside it because punters meet those brands, but no offshore licence — Curaçao, Anjouan, Tobique — gives the right to take bets from people in New Zealand, and the Department told such providers to withdraw with immediate effect.

The player side is set out differently from the operator side. Section 19(4) of the Gambling Act 2003, inserted in 2025, says an individual may not be convicted for placing a bet with an offshore betting operator in breach of section 74AAA. No published penalty for a player was found. The honest framing is that TAB NZ and Betcha carry the New Zealand safeguards, an offshore brand carries its own house rules, and the choice between them sits with the punter.

The data on odds, products and licences is current as of 31 October 2026 and has been checked against the Department of Internal Affairs register and the Racing Industry Act 2020, as amended.

Legality: the rule, the regulator and the practical effect

The Department of Internal Affairs is the gambling regulator under the Gambling Act 2003, and it monitors compliance with the betting prohibition set out in section 92A of the Racing Industry Act 2020. The Racing Industry Act 2020 establishes TAB NZ as the sole betting provider for racing and sports in New Zealand. The Racing Industry Amendment Act 2025 inserted section 74AAA: 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 change took effect on 28 June 2025, and the Department told providers serving New Zealand to withdraw with immediate effect.

There is no licensing route for another bookmaker and no licence register for betting, because there is only one lawful operator. The law does not geo-block offshore websites; it puts liability on the offshore operator. TAB and Betcha are the two lawful online brands of TAB NZ, run by Entain under the partnership described above; the page never presents Betcha as a rival bookmaker because it is not.

The Online Casino Gambling Act 2026 licenses online casino gambling only and does not license sports betting. TAB New Zealand’s right to apply for a casino licence does not extend the betting monopoly. Greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either.

What may be bet on: racing and sports betting from TAB NZ only. TAB NZ takes fixed-odds and tote bets; its published betting rules define bets such as Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie and Big6, and Multis and Same Game Multis. Live betting is listed in the TAB NZ apps; any statutory restriction on in-play markets is not established. No lawful New Zealand betting exchange exists and spread betting is outside TAB NZ’s sports-betting definition. Bets on politics and novelty markets are not established. There is no statutory per-bet cap; limits are TAB NZ’s own terms.

The age for TAB NZ betting is 18, with betting under 18 an offence under section 89 of the Racing Industry Act 2020. Land-based casinos are 20 — the two thresholds are separate. TAB NZ accounts need a verified New Zealand address and ID. The exclusion list applies across TAB and Betcha, and the harm-minimisation tools sit inside the app. There is no single national online-betting exclusion register; the register the casino law will require is for online casinos only.

The free Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa are the help lines. TAB NZ pays a Problem Gambling Levy of 0.74% in force from 1 July 2025 to 30 June 2028. Inland Revenue guidance says 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.

Advertising falls under the Advertising Standards Authority’s Gambling Advertising Code: ads must not target children (under 14) or young people (14 to under 18), judged by context, appeal and expected audience, must not encourage harm, and must be truthful with terms available. TAB NZ runs “bonus bets” promotions; no New Zealand rule on bet-bonus size or wagering terms was found, so quote only TAB NZ’s own terms.

Offshore operators supplying New Zealand residents pay online gambling duty (12% of profits since 1 July 2024, 16% from 1 January 2027). A duty being payable does not make an offer lawful — paying tax in a jurisdiction is not the same as holding a licence in New Zealand. The point-of-consumption charge on offshore racing and sports bets ceased on 30 June 2026.

The honest framing is the same as in the overview: TAB NZ and Betcha carry the New Zealand safeguards, an offshore brand carries its own house rules, and the choice sits with the punter with eyes open.

What a winning basketball bet pays back

The arithmetic of a winning bet is short and worth doing once. A stake of $10 at decimal odds of $2.10 returns $21 — the stake of $10 plus a profit of $11. A stake of $10 at odds of $1.50 returns $15, profit $5. A stake of $10 at odds of $4.00 returns $40, profit $30. The return is stake × odds; the net profit is stake × (odds − 1).

A combination bet multiplies the odds of the legs into one price. A two-leg multi at $1.80 and $2.10 is $1.80 × $2.10 = $3.78. A $10 stake returns $37.80 if both legs win, profit $27.80. A three-leg multi at $1.50, $2.10 and $1.80 is $1.50 × $2.10 × $1.80 = $5.67. A $10 stake returns $56.70 if all three legs win, profit $46.70. The price grows with each leg, and the chance of all legs winning falls with each leg. That is the trade-off a punter makes when building a multi.

A free bet works differently. The stake is not paid back with a win — a $10 free bet at $2.10 returns $21 minus the $10 stake that was never returned, so the net profit is $11. The formula for the average value of a free bet is free-bet amount × (odds − 1) ÷ odds × payout share of the market. The free-bet value falls as the price rises above 2.00, because the unreturned stake eats a larger share of the gross return. A punter who bets a free bet at long odds keeps less of the implied value than the headline price suggests.

The bonus turn-over is the requirement attached to a deposit bonus or a free-bet bundle. The required turnover is the bonus base multiplied by the wagering factor — for a $100 bonus with a 5× factor, $500 of qualifying bets must be placed before the bonus is withdrawable. The number of bets needed is the turnover divided by the stake per bet. The expected cost of clearing the offer is the turnover multiplied by the margin of the market the qualifying bets are placed on.

The bookmaker’s margin is the price the punter pays. On a 5% margin market, a punter who bets $500 to clear a bonus loses $25 on average before any skill edge is layered on top. On an 8% margin market, the same $500 costs $40 on average. A punter who clears a bonus on NBA moneyline markets pays a different cost than one who clears it on player props, because the margins differ.

The arithmetic above is the core of a smart bet. The odds, the margin and the expected cost are the three numbers a punter needs to know before claiming any offer, and the rest of the page is the framework around them.

The shape of the page, in one paragraph

Basketball betting in New Zealand is a market with one door — TAB NZ, through its two online brands TAB and Betcha — and a shelf of offshore brands that sit beside it because New Zealand punters meet them. The lawful option carries the New Zealand harm-minimisation tools, the New Zealand regulator and the New Zealand complaints route. The offshore shelf carries its own house rules, its own licences and its own product surface, and the choice between the two sits with the punter with eyes open. The price of any bet is the bookmaker’s margin, and the margin is what the rest of the page has been trying to make visible.

Decimal odds show what a winning $1 stake returns, including the stake. A $2.10 price returns $20 on a $10 stake — the $10 stake plus $11 profit. Two prices on opposite outcomes of the same market sum to slightly more than 100%, and the gap between the sum and 100% is the bookmaker’s margin.

How does basketball betting work end to end?

A punter opens an account with TAB NZ (TAB or Betcha), deposits via the operator’s published methods, selects a fixture from the basketball schedule, picks a market — moneyline, spread, total, player props or Same Game Multi — enters a stake, and confirms the bet. The bet settles at full time; live bets settle as the operator’s rules allow; the return is stake × odds.

Which bookmaker may lawfully take sports and racing bets in New Zealand?

TAB NZ is the only provider lawfully offering racing and sports betting to people in New Zealand, by section 74AAA of the Racing Industry Act 2020 in force from 28 June 2025. TAB and Betcha are its two online brands; they share one wallet, one exclusion list and one harm-minimisation framework.

How is the return on a bet worked out from the stake and the odds?

The return is stake × decimal odds. For a $10 stake at $2.10, the return is $21, and the net profit is $11. For a combination bet, the odds of the legs multiply into one price before the stake is applied.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the share of every dollar bet the bookmaker keeps across all outcomes. Two prices of $2.10 and $1.80 on opposite outcomes imply 47.6% and 55.6% — the 3.2% gap is the margin. A lower margin means a fairer price for the punter, and NBA and major FIBA markets typically carry 5% margins at a sharp bookmaker.
