Basketball runs through the New Zealand betting calendar on its own schedule. The NBA regular season tips off in October, runs 82 games per team through April, and the playoffs stretch into June. Every night, often into the Kiwi morning, fifteen or sixteen games sit on a board waiting for action. That volume is why NBA betting earns its own corner of any NZ punter’s slip: more fixtures than rugby league in summer, more markets per fixture than Super Rugby, and a rhythm that rewards punters who pick spots rather than chase them.

What makes NBA betting different in New Zealand is the legal ground underneath it. Since 28 June 2025, TAB NZ holds the only lawful licence to take racing and sports bets from people in New Zealand, under section 74AAA of the Racing Industry Act 2020. Its two online brands, TAB and Betcha, run as one operator. Everything else a Kiwi punter encounters online, Sportaza, Roobet, Alawin, RTbet, Thunderpick, RoyalistPlay, Spinbara, FunBet, LunuBet, sits outside that regime. That distinction shapes every practical question that follows: which app carries the lines, which markets show up, which consumer protections apply when something goes wrong.

What NBA Betting Looks Like Under the TAB NZ Monopoly

TAB NZ runs the only legal pipeline for NBA action in New Zealand. Its app, “TAB — Racing & Sports Betting”, is published on the NZ App Store by the New Zealand Racing Board, first released on 8 September 2014. The list of sports on the platform includes basketball alongside horse and harness racing, rugby union, rugby league and a wider spread of codes; pre-match and live wagering are both available. Streaming through Trackside 1 and 2 covers harness and thoroughbred racing; basketball coverage runs through scheduled markets and live pricing where the trading room opens them. Betcha, the second TAB NZ online brand published by Entain New Zealand since 6 August 2024, sits on the same licence and the same wallet, so a Betcha account is a TAB account under the hood. Both brands enforce the 18+ rule; the App Store age rating is 17+, set higher in-app to match the statutory minimum.

Where the platform gets specific is in the markets it shows. TAB NZ takes fixed-odds and tote (parimutuel) bets; racing bets follow the dedicated bet types defined in its terms, Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie, Big6, plus Multis and Same Game Multis whose legs all come from one event. On the sports side, the same multi-bet scaffolding applies, and live betting appears in both apps. The published list of NBA bet types on TAB NZ matches what international books price: head-to-head (moneyline), line betting (point spreads), totals (over/under), player props, and same-game multis on player performance, team totals and quarter/half lines.

What a punter cannot do through TAB NZ has just as much shape as what they can. There is no betting exchange, no New Zealand-hosted spread betting product, and no published politics or novelty betting line. Pools (tote) exist for racing and extend to a limited number of sports events; fixed-odds is the default. Limits are operator-level terms, not statutory rules, and they move with the market and the customer’s profile.

The Statute Behind the Monopoly

Section 74AAA of the Racing Industry Act 2020, added by the Racing Industry Amendment Act 2025 and in force since 28 June 2025, is the sentence the whole market turns on. It prohibits any person other than TAB NZ from offering racing or sports betting to a person in New Zealand, no matter where the operator is resident or incorporated. The Department of Internal Affairs told unlicensed providers serving New Zealand to withdraw with immediate effect when the change landed, and there is no licensing route for another bookmaker, because there is only one lawful provider.

Two clauses sit beside that prohibition and matter in practice. First, the ban covers events held inside and outside New Zealand; an NBA game in Los Angeles falls under the same rule as a Super Rugby match in Dunedin. Second, the Online Casino Gambling Act 2026 licenses online casino gambling only and does not extend the betting monopoly, so an offshore site holding a casino permit from 2026 onwards has no claim on a basketball bet. TAB New Zealand’s right to apply for a casino licence, when granted, will likewise leave the sportsbook monopoly untouched.

The greyhound code is winding down in stages from 1 August 2026, and from that date, offshore operators may not take bets on greyhound races either. Greyhounds are a racing market, not an NBA market, but the rule marks the boundary: when a code goes dark, the prohibition follows it out.

A note on the player 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 operator in breach of section 74AAA. No published penalty for a player was found, and New Zealand does not block bookmaker sites, so the practical risk to a Kiwi bettor who opens an offshore account sits in what the Department of Internal Affairs warns about: minimal consumer safeguards, possible refusal to return unspent credits, possible refusal to pay out large wins, and no New Zealand complaints route when something goes wrong. The law targets the operator. It does not punish the punter.

Tax and money. Recreational gambling winnings in New Zealand 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 separate case and must consult Inland Revenue or an accountant. On the operator side, TAB NZ pays the Problem Gambling Levy at 0.74%; overseas operators supplying New Zealand residents pay online gambling duty at 12% of profits since 1 July 2024 and 16% from 1 January 2027. Paying tax in New Zealand does not make an offer lawful under section 74AAA, a point worth repeating whenever a foreign brand’s local tax footprint comes up.

Responsible Gambling Under a Single Operator

When one operator holds the licence, the responsible-gambling framework runs through it. TAB NZ lists deposit limits, time-outs and self-exclusion in its app, and an exclusion applies across both TAB and Betcha brands because they share the same account infrastructure. Accounts require a verified New Zealand address and ID before a withdrawal is processed, which is the mechanism through which the self-exclusion register actually holds: a self-excluded person who tries to open a second account under a different email runs into the address check.

The age limit for TAB NZ betting is 18 (the betting-under-18 offence sits at section 89 of the Racing Industry Act 2020). The land-based casino age is 20, which can confuse newcomers; the casino limit does not transfer. There is no single national online-betting exclusion register, because the register the 2026 online casino law will require is for online casinos only, not sportsbooks.

Two free services sit behind every TAB NZ ad: the Gambling Helpline at 0800 654 655, with text support on 8006, run by the Salvation Army and funded through the Ministry of Health, and Safer Gambling Aotearoa, the government’s harm-minimisation programme. Both are advertised on TAB NZ’s responsible-gambling pages. When an offshore brand is used, neither service is reachable through the operator, and there is no New Zealand complaints route because the brand is not licensed here.

Predictions, Models, and What Smart NBA Betting Actually Looks Like

The volume of NBA fixtures creates a pull toward predictions: who wins tonight, who covers, which player goes over his points line. The pull is misplaced. Nobody, no model, no computer-pick service, no tipster account, knows the outcome of a basketball game in advance; anyone selling certainty is selling the same fantasy. What a smart NBA bettor does is closer to portfolio construction than forecasting.

Bankroll first. The stake on any single NBA game must sit at a fixed percentage of the betting bank, usually 1–2% for recreational punters and tighter for professionals, sized so that a losing streak of a dozen bets does not empty the account. The bettor who treats tonight’s four-leg multi as “the one that gets me back” has already lost the bankroll discipline behind it. A model is something else: a set of rules for when to bet and when to sit out, built on closing-line value, on pace-adjusted statistics, on rest days and travel, on the injury report that lands forty minutes before tip-off. A model loses too, more often than not, but it loses predictably, which is what makes bankroll management work.

A second layer sits at the market level. NBA totals have grown sharper in the last decade, and public money leans toward the over because high-scoring games are fun to watch; that public lean prices value into the under on certain matchups. Spreads move on star-player rests, which the league has loaded into the schedule since the 2023 Player Participation Policy. Player props break down by position and role: bench scorers on back-to-backs swing more than starters do, simply because their minutes are the first number the coach cuts. None of this predicts a winner; it sets the conditions for looking for prices that beat the closing line. Looking for prices that beat the closing line, over hundreds of bets, is what gives a serious NBA bettor an edge, if there is one.

Third, specialisation. The NBA has 30 teams, 1,230 regular-season games, and a calendar that runs nightly from October through April with the playoffs layered on top. The punter who follows three or four teams in detail will find sharper angles on those teams than the punter who bets everything. Specialisation is not a tip. It is a description of how human attention actually works against a market that runs every night.

What the betting public is told to look for, in tabloid tip columns and on social media, is the “best bet” of the night. The honest version is the best *priced* bet, the one where the line on offer sits above the punter’s own estimate of probability, sized against the bankroll, after the closing line has moved. That filter rarely leaves more than a couple of bets a night, and some nights it leaves none. That is what disciplined NBA betting actually looks like.

Bet Types and How NBA Odds Are Built

Every NBA market on TAB NZ’s board comes down to a price, which is a decimal number that turns stake into return. A $10 bet at odds 2.50 returns $25 gross ($15 profit, the original stake included). A $10 bet at odds 1.85 returns $18.50 gross ($8.50 profit). Same game multi-leg bets multiply the legs into a combined price: three legs at 1.90, 1.90, 1.90 combine to 6.859, which is 1.90 × 1.90 × 1.90, and the gross return on $10 becomes $68.59.

Three bet types carry most of the action on an NBA night. The moneyline, also called head-to-head in TAB NZ’s terms, is a bet on which team wins; in a strongly favoured matchup the favourite may sit at odds 1.20 and the underdog at 4.50. The point spread, called line betting in TAB NZ’s terms, levels the matchup by adding or subtracting points: the favourite lays 7.5 points, meaning they must win by eight or more for the bet to cash, and the underdog gets 7.5 points added to their final score. The total, over/under, is a bet on the combined score finishing above or below a published line, often 220.5 or so for a regular-season game.

Player props let a punter bet on individual performance: LeBron James over 27.5 points, a guard over 8.5 assists, a centre over 10.5 rebounds. Same-game multis (SGM) combine several props or a prop with the game result, multiplying the prices into a bigger payout. Period bets cut the game into halves or quarters, useful when a team has a historical tendency to start slow or finish strong.

The settlement logic behind these bets is published in TAB NZ’s terms. A bet on the moneyline settles on the result at the end of regular time plus overtime; an abandoned game settles as void unless the result was already determined. Player props settle on the official NBA box score; an injury withdrawal before the prop locks voids it in most cases. Same-game multis typically follow the void-one-leg-void-the-bet rule, which Sportaza’s terms, for the offshore comparison, spell out directly: if one selection in a Bet Builder is void, the whole slip is void. TAB NZ’s own equivalent rule sits in its betting rules.

The calculation that decides whether a bet is worth taking is the margin, and the margin hides in plain sight. In a two-way market at decimal odds 1.90 / 1.90, the implied probability sum is 1 ÷ 1.90 + 1 ÷ 1.90, which is 0.5263 + 0.5263, or roughly 105.26%. The 100% represents the fair book; the extra 5.26% is the bookmaker’s margin, also called overround or vig. The punter sees 1.90 / 1.90; the bookmaker keeps about 5.26 cents out of every dollar bet on this market, on average, before any edge the punter finds.

Stated as a band: on a balanced two-way NBA line at 1.90 / 1.90, the bookmaker’s margin sits around 5%, the exact figure depending on the rounding of the published price. Real NBA margins on the moneyline vary widely: a heavy favourite–underdog split (1.30 / 3.80) inflates the margin because the public overweights the favourite, while a tight game (1.95 / 1.95) compresses it. The 5% band is the working estimate for a competitive NBA line; prices further from even-money carry a wider margin, and props tend to carry the widest margin of any market because they’re harder to model.

The same calculation works on a three-way market, such as a regulation-time line that includes the draw. For odds 2.80 / 1.90 / 3.40 on Team A / Draw / Team B, the implied probability sum is 1 ÷ 2.80 + 1 ÷ 1.90 + 1 ÷ 3.40 = 0.357 + 0.526 + 0.294 = 1.177, a margin of about 17.7%. That wider margin reflects the difficulty of pricing the draw at the correct probability.

The free-bet calculation follows a different shape. A $10 free bet at odds 2.50, where the stake is not returned with the win, returns $25 gross to the bettor (odds × stake), but the punter’s net is $15 from a $0 outlay, while the book’s payout-share-weighted expectation on the market sits around 90% in competitive NBA pricing. The expected value becomes 10 × (2.50 − 1) ÷ 2.50 × 0.90, roughly $5.40, which is what the free bet is worth on average, not what it pays on a single win. TAB NZ’s “bonus bet” promotions carry their own terms, and only the brand’s own terms define the wagering conditions.

The NBA Season and Where It Fits in the Calendar

The league runs 30 franchises, 29 in the United States and 1 in Canada, the Toronto Raptors. The Boston Celtics hold the record with 18 championships. The Oklahoma City Thunder took the 2025 NBA Finals, beating the Indiana Pacers in seven games. The New York Knicks won the 2026 NBA Finals 4-1 against the San Antonio Spurs, clinching with a 94-90 Game 5 win on 13 June 2026; Jalen Brunson was Finals MVP. The Finals are played as a best-of-seven series, and the 2026 edition was played from 3 June through 13 June. The league’s modern origin sits at the merger that created the NBA on 3 August 1949, building on the Basketball Association of America founded in 1946.

The season architecture shapes the betting calendar. The regular season runs October through April, 82 games per team, a fixture list that delivers 15 or 16 games most nights. The playoffs layer onto the regular season in April, run through the conference finals in May, and resolve at the NBA Finals in June. The NBA Draft sits in late June, free agency opens shortly after, and Summer League carries into July and August. The Finals MVP, conference MVPs, regular-season MVP, Rookie of the Year, Defensive Player of the Year, and a dozen other awards all carry betting markets throughout their respective seasons.

For a New Zealand punter, the time-zone math dominates everything else. NBA tip-offs in the Eastern Conference run 7:00 pm or 7:30 pm local time, which is noon or 12:30 pm the next day in New Zealand throughout standard time; tip-offs in the Western Conference sit three hours later, so afternoon-evening Kiwi time. The schedule means most NBA action arrives in the middle of the New Zealand workday. That constraint shapes everything from live betting (open throughout work hours) to pre-match research (overnight), and it pushes serious NBA punters toward models that can price the slate before tip-off rather than reacting to in-game markets.

In-season tournaments and All-Star Weekend sit inside the calendar too. The NBA Cup, the league’s in-season tournament, runs from November through early December and carries its own knockout bracket; All-Star Weekend sits mid-February with the All-Star Game on Sunday night. Each event has a market.

Top 10 NBA Betting Options Available to New Zealand Punters

Because section 74AAA restricts lawful online sports and racing betting in New Zealand to TAB NZ’s two brands, every option below is either one of those two brands or an offshore bookmaker that takes bets from people in New Zealand without a New Zealand licence. TAB and Betcha are one operator (TAB NZ) under two brand names; the rest are a reference set, not recommendations, and each is described on its own terms.

TAB

TAB is the older of TAB NZ’s two online brands and the one most Kiwi punters know by reflex. The product covers the racing codes (thoroughbred, harness, greyhound while it lasts) and a sportsbook that includes basketball. NBA markets show up alongside NRL, Super Rugby and the football codes, and live betting is available on selected NBA fixtures. The app carries a 17+ App Store age rating; the platform applies 18+ as a customer rule, matching the statutory betting age. Safer-gambling tools, deposit limits, time-outs and self-exclusion, sit in the responsible-gambling section of the app, and a self-exclusion applies across TAB and Betcha because both brands run through the same wallet.

For a punter who wants the NBA on the same slip as the All Blacks, TAB is the path that keeps them inside New Zealand’s harm-minimisation framework. The trade-off is product depth: TAB NZ’s trading room runs thinner than the bigger offshore books, especially on player props and same-game multis, and live markets on less-prominent games may close earlier than they will elsewhere.

Verdict: TAB is the right choice for the Kiwi punter who wants NBA betting inside a regulated framework with NZ-specific consumer protections. The breadth of markets is narrower than the offshore brands a Kiwi can find, and live betting on smaller slates is more limited, but the regulatory clarity and the integration with the local racing products are the trade-off for that.

Betcha

Betcha is the newer TAB NZ online brand, published by Entain New Zealand Limited since 6 August 2024, sitting on the same section 74AAA licence and the same product backbone as TAB. A Betcha account is not separate from a TAB account for harm-minimisation purposes: the self-exclusion register, the deposit limits, the address verification, and the 18+ enforcement run through TAB NZ’s infrastructure. The brand itself leans into the Entain product template and onto a younger positioning than TAB.

For an NBA punter, the practical question is whether Betcha offers markets TAB does not. The product set is the same, so the answer is no; what Betcha adds is a different app experience and the same legal and consumer framework as TAB.

Verdict: Betcha suits the punter who prefers Entain’s app template and is happy with TAB NZ’s product range and protections. Both brands must be understood as one operator for harm-minimisation and exclusion purposes, not as a choice between rivals.

Alawin

Alawin’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting, virtual sports and esports also offered. As an offshore bookmaker, it is not licensed to take bets from people in New Zealand and offers no local complaints route. The Department of Internal Affairs’ warning applies.

For a Kiwi punter evaluating Alawin, the consideration is straightforward: the platform lists basketball, so NBA markets are likely present, but consumer protection is the offshore rulebook, not New Zealand’s.

Verdict: Alawin is mentioned for completeness because Kiwi punters encounter it. The product breadth is real, but the New Zealand protection gap makes it unsuitable for anyone who values the regulatory framework TAB NZ provides.

RTbet

RTbet covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting and virtual sports. Its Curaçao licence is invalid for taking bets from New Zealanders, and it offers no local complaints route.

Verdict: RTbet’s basketball offering sits at parity with its peer offshore brands. The lack of NZ-recognised protection is the deciding factor for a Kiwi punter; a stake at RTbet is unprotected when something goes wrong.

Roobet

Roobet covers soccer, basketball, tennis, Counter-Strike, FIFA, baseball, ice hockey, MMA and table tennis, with 18+ as the customer rule. Its Curaçao licence (OGL/2024/687/0427) is invalid for taking bets from New Zealanders; no local complaints route applies.

Verdict: Roobet’s basketball product is established within its peer group. The minimum age is internal; the consumer protection layer is not.

Thunderpick

Thunderpick runs esports-first, with CS2, League of Legends, Dota 2 and Valorant leading the slate, and a sportsbook offering markets from the Champions League to the NFL. A cash-out feature is available. Its Curaçao licence (OGL/2024/677/0722) is invalid for taking bets from New Zealanders; no local complaints route applies.

Verdict: Thunderpick suits a Kiwi punter whose interest runs toward esports and who is comfortable with the offshore framework. For NBA-focused punters the cash-out feature is the draw, and the same protection gap applies.

RoyalistPlay

RoyalistPlay offers live betting, sports promotions, results and a schedule, with basketball among the top sports, alongside separate esports and Predictions sections. Its Tobique Gaming Commission licence (No. 0000002) is invalid for taking bets from New Zealanders; no local complaints route applies.

Verdict: RoyalistPlay’s product depth is comparable to peer offshore brands; the licensing gap is the deciding factor.

Sportaza

Sportaza offers cash out before settlement, Bet Builder (a void leg voids the whole slip), multiples, Asian lines and interval markets in 1, 5, 10 or 15-minute ranges. Its Anjouan licence (ALSI-202606064-FI2) is invalid for taking bets from New Zealanders; no local complaints route applies.

Verdict: Sportaza’s market structure, especially the Bet Builder and Asian lines, is the draw. The same offshore protection gap applies.

Spinbara

Spinbara advertises a first deposit bonus and a sport crypto welcome bonus, alongside a casino welcome bonus. It is not licensed to take bets from New Zealanders and offers no local complaints route.

Verdict: Spinbara’s sportsbook is presented with promotional pricing, not product depth, in the available information. The licensing gap is the same as its peers.

FunBet

FunBet covers football, ice hockey, American football, basketball, volleyball, tennis, rugby and baseball, with live betting and a bookmaker advertised as open 24/7. It is not licensed to take bets from New Zealanders and offers no local complaints route.

Verdict: FunBet’s 24/7 framing suits the NBA’s nightly schedule; the product breadth on basketball is comparable to peer offshore brands. The protection gap is unchanged.

Choosing Where to Bet on the NBA in New Zealand

The legal answer is TAB NZ: TAB or Betcha, one operator, two brands. The structural answer is that the choice for a Kiwi punter is between lawful access with New Zealand consumer protections and a wider product with offshore rules. A punter who values problem-gambling tools, a self-exclusion register that actually holds, ID verification, and a regulator to complain to, is a TAB NZ punter. A punter who values deeper player-prop books, more same-game multi combinations, and a wider live offering, and is comfortable with the protection gap the Department of Internal Affairs warns about, is using an offshore bookmaker.

The reading the Department of Internal Affairs offers in its guidance is that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits, and may not pay out large wins. There is no published penalty for a player under New Zealand law. The punter’s risk is contractual and operational, not criminal.

For New Zealand residents, the practical order is: open a TAB NZ account first; verify identity and set a deposit limit; explore the NBA markets and the live betting before funding a large bankroll; understand TAB NZ’s self-exclusion and time-out tools; and read the responsible-gambling page before the first bet. For anyone who already bets offshore, the same setup runs in reverse: check the book’s withdrawal terms before depositing, understand the licence the book claims, and weigh whether the product difference is worth the protection gap.

How to Read NBA Odds and Find Value

Three rules run through the practical analysis of an NBA betting card.

First, compare the price to a fair value, not to the previous price. A line that moved from 1.90 to 1.85 is not necessarily better or worse; it is a different price with a different implied probability. The fair-value reference is the punter’s own model, not the line that was posted an hour ago.

Second, watch the closing line. The price available right before tip-off is the sharpest estimate of true probability that the market will produce, because the late money reflects the bets of the most informed punters and the trading room’s final adjustment. A punter who can beat the closing line over hundreds of bets has an edge; a punter who cannot is paying the margin.

Third, understand the markets the margin hides in. Moneyline on heavy favourites runs a wide margin because the public overweights the favourite. NBA totals have compressed in recent years as the betting public has learned pace and efficiency. Player props carry the widest margin in the book because they are hardest to model, and same-game multis compound the margins across legs. The punter who wants the lowest hurdle to an edge is on the side or total line of a competitive game, not on a multi combining four player props.

Where the NBA Calendar Touches New Zealand Betting

November, December, January, February, March, April, May, June: the NBA runs through all of them, and the betting calendar runs with it. The regular season opens in October and runs 82 games per team. The playoffs extend the season into June, when the NBA Finals close the year. Summer League fills the gap between the Finals and the next season. The All-Star Weekend sits mid-February, and the NBA Cup sits late November through mid-December. Each beat in the calendar carries its own markets.

The awards markets run in the second half of the regular season: MVP, Rookie of the Year, Defensive Player of the Year, Sixth Man, Most Improved Player, Coach of the Year. Finals MVP and Championship futures run all year. A punter who wants to bet the title race months before the playoffs reads the futures board and the schedule, not the tip sheets.

Responsible Gambling and the Limits That Matter

Three limits apply to TAB NZ betting: the age limit (18+), the verification limit (a verified NZ address and ID before withdrawal), and the player’s own chosen limits (deposit caps, time-outs, self-exclusion). These run through TAB and Betcha together because they share the wallet.

What the limits are *not* is a substitute for bankroll discipline. A punter who sets a deposit limit and then uses two brands to double it has defeated the tool without breaking any rule. The problem-gambling levy TAB NZ pays, 0.74% of betting turnover, funds the Ministry of Health’s gambling-harm programmes and the Gambling Helpline at 0800 654 655 (text 8006).

The offshore brand a Kiwi punter encounters has none of these protections. Self-exclusion is the operator’s own product; an offshore brand may not honour a self-exclusion request, may not verify identity, and may not have a responsible-gambling team to call when a punter asks to close the account. The choice between TAB NZ and the offshore bookmaker is, at the limit, a choice between a framework and an absence.

The Question Behind the Search

People who search for “nba betting in new zealand” are usually looking for three things at once: which app to use, what markets show up, and whether the bookmaker they’re considering is legitimate. The first and third answers are settled by section 74AAA: TAB NZ’s two brands are lawful; everything else is not. The middle answer, which markets show up, is the practical question, and it has a less tidy answer, because product depth varies across the offshore brands a Kiwi punter encounters even when those brands are barred from operating here.

A punter’s best move, before picking any NBA bookmaker, is to read the betting rules on the brand’s own site and to check the licence claim against a public register where one exists. A bookmaker that doesn’t publish a betting rules page, or that names a licence no regulator recognises, is the same answer either way.

Frequently asked questions about NBA betting in New Zealand

Can NBA players bet on other sports?

NBA players are barred by the league from betting on NBA games, but their own rules on betting on other sports depend on the collective bargaining agreement and the player’s individual team policy. The question that matters for a New Zealand punter is unrelated: the legal provider for NBA betting here is TAB NZ under section 74AAA of the Racing Industry Act 2020, not the NBA itself.

How do second-half bets work in the NBA?

Second-half, or “second-half line” bets, settle only on the points scored in the second half, including overtime when the game goes to OT in the NBA. The score at halftime is the starting point. A bet on Team A −3.5 in the second half is decided entirely by the second-half score, not the full game. Same-game multis combining a first-half and second-half line follow the same settlement logic: each half settles independently.

How do I bet on the NBA?

The path a Kiwi punter takes is: open a TAB NZ account (TAB or Betcha, same operator), verify identity, set a deposit limit, browse the NBA markets under the basketball heading, and place a bet on the chosen market. Live betting is available on selected fixtures. Offshore bookmakers also show NBA lines but are not licensed to take bets from people in New Zealand under section 74AAA.

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

TAB NZ, operating through its two online brands TAB and Betcha, is the only provider lawfully able to take online racing and sports bets from people in New Zealand, under section 74AAA of the Racing Industry Act 2020, in force since 28 June 2025. No other brand is licensed here, and there is no licence register for bookmakers because the law creates a single lawful provider.

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

Return on a winning bet is the stake multiplied by the decimal odds. A $10 bet at odds 2.50 returns $25 gross, including the original $10 stake, so the net profit is $15. For a multi-leg bet the odds multiply leg-by-leg: three legs at 1.90, 1.90 and 1.90 combine to 6.859, and a $10 bet returns $68.59 gross.

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

The margin is the percentage of every dollar bet that the bookmaker keeps, on average. In a two-way market at odds 1.90 / 1.90, the implied probabilities add to about 105.26%, so the margin sits around 5%, with the exact figure depending on rounding. A market priced at 1.95 / 1.95 has a smaller margin; a market priced at 1.30 / 3.80 has a much larger one. The margin is what makes beating the closing line valuable, because a punter who wins more often than the implied probability over hundreds of bets is collecting the margin minus the losses, which is the only way the long-term edge shows up.
