A sign-up bonus is a promotional offer for new players who have not previously held an account with a bookmaker. To claim the bonus, you usually need to make a qualifying deposit, or a deposit plus a bet. We’ve reviewed the welcome offers from BetWinner (170 NZD), 20Bet (150 NZD) and 22bet (220 NZD).

22bet – 100% Welcome bonus up to 220 NZ$ for sports betting

Overview: New players can get a 100% Welcome bonus up to 220 NZ$ with a minimum deposit of 2 NZD. The bonus is credited automatically and must be wagered ×5 on accumulators with at least three selections at 1.40+ odds within seven days.

Verdict: The 22bet offer tops our ranking thanks to its generous 100% Welcome bonus up to 220 NZ$, which is higher than most competitors, and the low entry threshold of just 2 NZD makes it accessible to almost any player. However, the wagering requirements could be difficult for some due to the restriction of betting exclusively on accumulators.

BetWinner – 100% first deposit bonus of up to 170 NZD

Overview: Players can claim a 100% first-deposit bonus up to 170 NZD with a minimum deposit of 1 NZD. The bonus is credited automatically and must be wagered x5 on accumulator bets with odds of 1.40+ within 30 days.

Verdict: Although the requirements are similar to other bonuses, BetWinner ranks second due to the lower maximum bonus of 170 NZD. The wagering conditions are simple and clear, and the 30-day period gives players plenty of time to complete them.

20Bet – 100% UP TO 150 NZD First deposit bonus for sports betting

Overview: To claim the bonus, make a qualifying deposit of at least 15 NZD. A 100% bonus of up to 150 NZD is credited automatically. The bonus must be wagered 5× on accumulator bets with two or more selections at odds of 2.00 or higher within 30 days.

Verdict: The wagering conditions are easier thanks to two-selection accumulators, but the 2.00+ odds requirement and higher deposit place this offer third in our ranking.

Free bets are a type of bonus that allows new and existing players to place single or accumulator bets without risking their own money. Free bets can be claimed for registration or for placing bets on events. We’ve ranked the top 3 betting sites with free bets: Betandplay (60 NZD), 20Bet (150 NZD), and 1xBet (204 NZD).

1xBet – ¡Olé, La Liga!

Overview: Place single bets with odds of 1.50+ and accumulator bets with odds of 1.40+ on La Liga matches from 5 NZD, and receive a free bet of up to 204 NZD depending on your total wagers. The free bet must be used within seven days.

Verdict: Despite the strict requirements, 1xBet ranks first in our list because players can earn up to 204 NZD each week, and to cash out free bet winnings, only a four-selection accumulator at 1.50+ odds is needed.

20Bet – Saturday Reload Weekly Reload Bonus for Sports Betting

Overview: To claim the bonus, place at least 40 NZD in bets from Monday to Friday, then deposit 15 NZD on Saturday with the promo code SRB to receive a 100% free bet up to 150 NZD. The bonus must be used within two days on accumulators with at least two selections.

Verdict: Thanks to weekly availability and straightforward rules, the 20Bet bonus suits a wide range of players. However, the two-day expiry and accumulator requirement place it second in our ranking.

Betandplay – First Deposit bonus 50% up to 100 NZD

Overview: Only new players can claim this free bet. Make your first deposit of at least 1 NZD, and receive a 50% bonus up to 100 NZD automatically. The bonus must be wagered 20× within seven days on bets with odds between 1.01 and 3.00.

Verdict: Despite the low entry threshold, we rank Betandplay lower because the strict x20 wagering makes it challenging for players of any experience level.

Reload bonus is a promotion for existing players on subsequent deposits. Usually, the bookmaker sets specific days when players receive an extra percentage on their deposit. We’ve collected reload offers from 22Bet (204 NZD), Rich Royal (1,000 NZD), and N1Bet (450 NZD).

Rich Royal – Weekly reload bonus 50% up to 1,000 NZD

Overview: This offer applies to the first deposit of the week. Deposit at least 40 NZD and get a 50% bonus up to 1,000 NZD, to be wagered within 30 days according to the betting requirements.

Verdict: Rich Royal ranks first thanks to the generous 1,000 NZD bonus. The wagering process is simple and suitable for players of all levels.

N1bet – Weekly reload 30% up to 450 NZD

Overview: Deposit at least 1 NZD and get a 30% free bet up to 450 NZD. The free bet must be used on bets with odds of 1.50–2.00, with no additional wagering requirements.

Verdict: Despite the strict odds restrictions, N1bet’s reload offer ranks second thanks to the absence of any wagering conditions on free bet winnings.

22bet – Reload: a weekly bonus 100% up to 204 NZD for sports betting

Overview: The bonus is available only on Fridays. Deposit at least 3 NZD and get a 100% bonus up to 204 NZD. The bonus must be used within 24 hours on accumulators with three or more selections, each with odds of 1.40 or higher.

Verdict: Overall, 22bet offers standard reload conditions, but the limited availability and small bonus place it third in our ranking.

The referral bonus is available to all players and allows you to invite friends to earn bonus funds or free bets for sports betting. Here are some examples of referral offers from bookmakers: 1xBet (unlimited), Betcha (20 NZD), and Betandplay (75 NZD).

1xBet – Join the 1xBet referral program and earn extra income by inviting friends!

Overview: Copy your referral link from your account, share it with friends or on social media, and earn up to 15% of 1xBet’s profits with no wagering requirements.

Verdict: The 1xBet referral programme lets players build their network and earn up to 15% of the company's profits, with unlimited referrals and earnings, making it the top choice.

Betcha – Bring a friend along and get 20 NZD bonus cash each

Overview: Copy your referral link and invite a friend to sign up. You’ll receive a 20 NZD bonus, usable within 7 days with no wagering requirements.

Verdict: Betcha offers simple referral conditions: invite a friend, complete registration, and get 20 NZD to use on any sports bets, making it flexible and straightforward, ranking it second.

Betandplay – Invite your Friends and get a Bonus

Overview: To get the bonus, your referred friend must sign up via your referral link and make a qualifying deposit. You’ll then receive a 75 NZD bonus, usable in the casino.

Verdict: Although Betandplay offers 75 NZD, higher than our second-place offer, it’s limited to the casino. Because of this restriction, the bonus ranks third, even though it allows full access to the casino section.

The Cashback Bonus allows players to receive a fixed percentage back on their losses. These bonuses can be daily, weekly, or monthly. We’ve selected offers from the following bookmakers: N1bet (150 NZD), BetWinner (1,771 NZD), and RTbet (1,000 NZD).

BetWinner – Place bets every day and get 3% weekly cashback

Overview: Place bets throughout the week with odds of 1.50 or higher and get 3% cashback on your total losing bets, up to 1,776 NZD. The cashback is credited as real money, with no wagering requirements or expiry date.

Verdict: Clear, straightforward rules make this offer ideal for both new and experienced bettors. The generous bonus amount and lack of wagering requirements secure BetWinner the top spot in our ranking.

RTbet – Cashback bonus 10% up to 1,000 NZD

Overview: Place bets from Monday to Sunday and get 10% cashback up to 1,000 NZD if your total losses exceed your winnings. The bonus must be requested via customer support and wagered three times, with no additional conditions.

Verdict: Although the bookmaker offers a maximum bonus of 1,000 NZD, we rank it second because the cashback applies only to net losses, reducing player benefit, and the bonus requires x3 wagering, even without extra conditions.

N1bet – Personalised Weekly Cashback Up To 10%

Overview: To qualify for the bonus, you must make at least six deposits during the qualifying week. Cashback of 10% up to 150 NZD is awarded only if your losses exceed your wins. The bonus must be wagered 3x within 24 hours, with no additional conditions.

Accumulator Boost is an automatic increase of the player’s winnings on accumulator bets, with the bonus credited instantly upon settlement and no wagering requirements. Here, we highlight the best offers available in New Zealand from 20Bet (100%), N1bet (70%), and NetBet (50%).

20Bet – Boost your odds! Up to 100% extra cash on combo bets

Overview: After logging into your account, go to the Sports section and create an accumulator bet slip with three or more events, each with odds of 1.20 or higher, from both live and pre-match options. The credited winnings have no wagering requirements.

Verdict: Despite not being suitable for every betting strategy due to market limitations, 20Bet’s offer stands out thanks to the lack of restrictions on sports, maximum winnings, or stake amounts, securing the top spot in our ranking.

N1bet – Basketball Comboboost up to 70%

Overview: To qualify for the boost, your accumulator must include only basketball events, with at least four selections at odds of 1.30 or higher and a total accumulator odds of no less than 2.86. The awarded bonus does not require wagering.

Verdict: Although N1bet offers better qualifying conditions, we place it second due to its lower 70% boost and limited availability for basketball only.

NetBet – Acca Boost up to 50% more winnings

Overview: In the Sports section, select the Football category and create an accumulator bet with at least three selections, each at odds of 1.30 or higher. The maximum 50% bonus is available for 20 selections in a single bet slip.

Verdict: The bookmaker offers simple and transparent bonus conditions, similar in mechanics to previous competitors. However, it ranks third in our list due to its limitation to football and the 50% maximum boost. Still, this offer suits both beginners and experienced bettors alike.

With lucrative sportsbook bonuses, it can be tempting, and you may make poor financial decisions. It's essential to know the rules and your limits. Tips for safe gambling:

• Set your own betting limits and stick to them.
• Avoid chasing losses.
• Monitor the time and money spent on the platform.
• Use self-exclusion tools if you feel overly involved.
• Seek professional help if addiction is uncontrollable.

Always play responsibly, set limits, and use only surplus funds. Treat betting as a sport, not a way to earn income.
