While you must deposit $50 to activate the promo, we love that there’s no cap on winnings or withdrawals!

Types of online casino bonuses
Casino bonuses are designed to attract new players and reward existing players for sticking around. Typically, welcome bonuses are the most generous, but some real money online casinos offer high match percentages and reload bonuses as part of VIP or loyalty programmes. Here's the best casino bonuses you can claim in NZ:
Most welcome bonuses require an initial deposit, but some casinos may award no deposit bonuses, no wagering offers and cashback. We usually see a match percentage up to a specific amount and/or free spins, such as Wildz’s 100% up to $1,000 and 200 free spins bonus. The best welcome bonuses have validity periods of 30 days (or more) and 35x wagering requirements to give you the best shot at fulfilling the T&Cs.
Slot buffs should look for free spins promos, as they provide bonus spins on specific slot games or a casino’s entire pokies library. After funding your account, you will either automatically receive free spins or be required to input a bonus code to claim. You may also be awarded free spins at a no deposit bonus casino, allowing you to gamble risk-free and still be in with the chance of winning real money.
The highly sought-after no deposit bonus is a rare find as the casino stands a lot to lose. While you don’t have to put your own money on the line, no deposit bonuses are often subject to strict T&Cs to minimise the casino’s losses. You’ll find wagering requirements up to 200x and average max win limits of $20. Still, they provide a solid way to explore a new site and try games without risking your bankroll.
If you want to play online pokies without making a financial commitment, no deposit free spins are the perfect way to get started. As they are restricted to specific slot games and help casinos promote certain titles, they are more common than no deposit cash bonuses. Once you’ve cleared the T&Cs, you can use your winnings to explore the rest of the casino’s game library or withdraw your funds as cash.
High roller casino bonuses are designed for big spenders. They award cashback or higher match percentages on large deposits, often up to $4,000 or more. You can usually claim a high roller bonus through a VIP programme, where you accumulate points and advance the levels to land bigger bonuses and exclusive perks. Some sites like Lucky Spins, offer high roller bonuses as part of ongoing promotions.
Live casino bonus
This bonus is only eligible on live dealer games and gameshows like Crazy Time and Sweet Bonanza Candyland. As most live casino games are expensive to produce and have high RTPs of up to 99%, bonuses tend to have higher minimum deposits ($50+) than other casino promos. However, many come with low 15x wagering requirements, like Rizk’s 100% up to $3,500 live dealer bonus, making it easier to meet rollover conditions.
While you may be required to deposit real money to claim a no wagering bonus, any cash you win is yours to keep – no strings attached! This is a sweet deal but most casinos cap winnings at $100 and limit the game selection to prevent players from using the bonus strategically across various games. If you want greater flexibility at a reduced risk, opt for low wagering casino bonuses with requirements of 5-25x.
Some gambling sites only accept crypto payments and reward NZ players depositing with Bitcoin and other digital currencies. For instance, Mirax Casino offers a 325% up to 5 BTC welcome offer plus 150 free spins – one of the best crypto bonuses around. Some operators may also offer a crypto casino no deposit bonus, but like standard no deposit promotions, these are hard to come by in New Zealand.
Mobile casino bonus
You can enjoy the same online casino bonuses, including deposit matches, free spins, no deposit bonuses and ongoing promos, from your smartphone or tablet. Many NZ mobile casinos even offer exclusive bonuses you can only get by playing via the dedicated casino app. Mobile casinos provide additional advantages, such as one-tap payments and enhanced security features like face and touch login.
Match deposit bonuses are a type of minimum deposit offer available to new and existing players. It’s one of the best online casino bonuses, as it matches your deposit up to a specific percentage. For example, Spin Casino has a 100% match bonus of up to $400 on your first deposit, meaning you’d get $800 to play with if you maxed the deposit value.
As the name suggests, a first deposit casino bonus is awarded after you’ve signed up and funded your account for the first time. We commonly see these offered as a match deposit bonus, but some NZ online casinos may reward cashback or free spins to get you started. These also carry wagering requirements, minimum deposits and game restrictions.
Online casino bonuses explained
A casino bonus is a promotion offered to new and existing players. Depending on the type of bonus, you will receive rewards like free spins, free cash, cashback and bonus credits.
Most casino bonuses are expressed as a percentage of your deposit, which usually ranges between 50% and 200%. For instance, a 100% deposit match bonus means if you deposit $100, you receive an additional $100 in bonus funds.
Many online casinos also include an ‘up to’ as part of the offer, for instance 100% up to $1,000. This means that if you deposit less than the full amount, you’ll only receive 100% of the amount you deposited, so if you deposit $20, you get $20 extra from the casino.
How to claim an online casino bonus
Now you’re familiar with the different types of online casino bonuses. Here’s a simple guide on how to claim at an NZ online casino:
Research the best NZ casinos
Find reputable online casinos in New Zealand with transparent T&Cs. Top-rated sites, such as Jackpot City and Spin Casino, are great sign-up bonus casinos, giving you 60 days to meet the T&Cs.
Read the casino's T&Cs
Before depositing real money, carefully read the T&Cs to ensure the conditions are acceptable and give you a fair chance at withdrawing your winnings.
Deposit real money or sign up
Register an account and, if necessary, make a qualifying deposit to activate the offer. Remember, some real money casinos also require a bonus code.
Meet the playthrough requirements
Play games that count towards the wagering requirements to give you the best chance at withdrawing your winnings before the bonus expires.
Withdraw your winnings
This is entirely optional. After meeting the requirements, you can cash out your winnings or use them to continue playing.
Use our bonus wagering tool to calculate your offer
Wagering requirements tell you how much of your deposit and/or bonus funds you must bet before withdrawing your winnings.
If you deposited $100 on Jackpot City’s 100% up to $1,600 bonus, you’d need to wager $3,500 ($100 x 35), as the offer has 35x playthrough conditions. However, that’s if you’re playing games that contribute 100%. Suppose you play table games which contribute 8%. You’d need to wager $43,750 ($100 x 35 ÷ 0.08). That’s why casino games with 100% weighting give you the best chance at clearing the requirements.
Use our bonus bet calculator to find out how much you’d need to wager to withdraw any winnings at your chosen casino:
💡 Look for bonuses with low rollover terms (10-30x) and stick to games that contribute 100% towards wagering to maximise your payout potential and improve your chances of withdrawing bonus winnings.
Casino bonuses – terms & conditions explained
Before claiming a casino bonus, it’s essential that you read through the T&Cs. These rules determine the conditions you must meet before withdrawing any bonus winnings. Here are the standard requirements most casinos attach to bonuses:
This refers to the number of times you must bet bonus funds before withdrawing them from your casino account. Winning and losing betting rounds count toward the rollover requirements.
Most casinos have a 30x to 50x wagering requirement, which is in line with the industry standard, while anything over 50x is considered high. There are also low wagering bonus casinos, with requirements under 35x which can increase your chances of cashing out sooner.
Most online casinos require a minimum deposit to activate the bonus. You’ll find $1 deposit bonus casinos in NZ alongside platforms that require up to $5, $10, and $50 minimum deposits. Casinos with minimum deposit requirements typically offer players a matched bonus up to a certain amount. For instance, Spin Casino has a $10 minimum deposit but lets players get a 100% match bonus up to $1,000.
You must fulfil the conditions outlined in the T&Cs within a time limit. This usually ranges between seven and 30 days, but sites like Jackpot City are generous and give you 60 days to clear the requirements. Failing to satisfy the conditions within the time limit means you forfeit your bonus funds and winnings.
Not all games are eligible for bonuses, and not all games count toward playthrough requirements equally. For instance, online pokies may contribute 100%, while table games contribute 15%. Some games may be excluded altogether due to having a high return to player (RTP) percentage, as some casinos perceive the chance of a player landing a massive payout as too risky.
Some gambling platforms restrict how much you can withdraw in a single transaction. There is also a chance that some payment methods aren’t eligible for casino bonus withdrawals. Skrill and Neteller are typically excluded, as bonus hunters use these methods to create multiple accounts and exploit promotions.
Casino bonus codes are a string of letters and/or numbers you must enter to activate a specific promotion. They are usually required for no deposit bonuses on registration, but existing players may need to enter bonus codes to claim exclusive promotions and rewards such as birthday bonuses. Bonus codes may also have expiry dates, so don’t sit on these too long if you want to claim.
New casino bonuses for NZ players
New online casinos usually offer more competitive bonuses than established sites to encourage players to sign up and become a recognised brand. For example, Casino Days (launched in 2020) awards 100% up to $1,000 and 100 free spins, compared to Ruby Fortune (established in 2003), which offers 100% up to $750.
You’ll likely find rewarding promotions, too, with free spins, match deposits, cashback, refer-a-friend bonuses and exclusive offers tailored to high rollers or loyal players. Here’s a quick overview of how bonuses at new online casinos compare to offers at established gambling sites:
| New casino bonuses | Established casino bonuses |
|---|---|
| ✅ Higher bonus amounts and larger welcome packages across multiple deposits | ✅ Trusted online casino promotions with clear T&Cs |
| ✅ Offer gamified promotions such as level-ups and progress bars that unlock bonuses | ✅ Usually offer higher-value loyalty programmes with luxury benefits like event invites and sports cars |
| ✅ Lower wagering requirements to entice new sign-ups | ✅ Support more payment methods, providing greater flexibility for deposits and withdrawals |
| ✅ Greater range of promotions, including cashback, birthday bonuses, refer-a-friend offers and more | ✅ Longer validity periods, with sites like Jackpot City giving you 60 days to meet the T&Cs |
| ❌ Unproven track record, so few player reviews to verify the experience | ❌ Some sites impose high wagering requirements of over 50x |
| ❌ May have shorter validity periods due to being more generous | ❌ Rarely offer certain types of bonuses such as no deposit and cashback |
Casino bonuses for existing players
The best sites in New Zealand offer bonuses to loyal online casino players, including reload offers, loyalty rewards and tailored promotions based on your gaming preferences. Here are the best casino bonuses for existing players:
Reload bonuses: Returning players who deposit real money can enjoy this casino online bonus. Typically, these are matched deposit offers up to 100%, but we’ve seen some casinos triple your deposit value.
Referral bonuses: You’ll unlock this bonus by successfully inviting friends and family to register and deposit at a casino site. The reward is usually fixed, such as 50 free spins or $20 per sign-up.
Cashback: Some NZ casinos may award cashback up to a specific percentage e.g. 20% on losses. We’re seeing this offered more in 2025, and it provides an excellent way for you to recoup some funds.
Loyalty programmes: Top online casinos provide tailored promotions as part of loyalty or VIP programmes. The rewards are usually scaled and unlocked depending on how many points you’ve earned by placing regular wagers on games. Besides bonuses, you get additional perks, such as VIP event access, instant cash prizes and faster withdrawals.

Our tips on how to take advantage of online casino bonuses
Follow these expert tips on how to get the most benefit out of a casino bonus and distinguish the good the ones from the bad:
Look for fair playthrough requirements: The industry standard is 35x, so anything within this range or lower provides excellent value. Bonuses with wagering requirements of 50x and higher may make it difficult to withdraw any associated winnings.
Play high RTP pokies: Slot games usually contribute 100% towards wagering, meaning you won’t need to bet as much as your bonus funds to meet the T&Cs. High RTP slots also provide better long-term returns, while low RTP games will eat through your funds faster.
Maximise your deposit: Most bonuses scale with your deposit, so depositing more will increase the bonus money you receive. However, only do this if you can afford to.
Be aware of max win caps: Choose bonuses with high maximum win limits to enjoy more of your winnings. Some offers, particularly no deposit promos, have limits of $20, meaning even if you won $100, you won’t be able to withdraw more than $20.
Check the expiry time: Most online casinos give you 7-30 days to use your bonus funds. Thirty is better than seven, as you get more time to meet the T&Cs.
‘Before claiming a bonus in an online casino, I always check the T&Cs. This helps me avoid surprises with time limits or game exclusions that could impede redeeming the bonus money. Opting for a casino bonus with more favourable requirements also helps manage my bankroll and increase my chances of getting an actual payout.’
How we rate casino bonuses
We have a thorough review process at OCNZ and only recommend an online casino that meets our extensive criteria. Here’s what we check when rating casino bonuses:
We pay a lot of attention to the types of bonuses available at online casinos to ensure you get the most out of your money. Our top-rated sites offer new and existing player bonuses, including free spins, match deposit offers and loyalty promotions.
Some online casinos impose strict bonus restrictions that require you to jump through many hoops before you can cash out your winnings. Our featured real money online casinos have reasonable wagering requirements of 30-40x, validity periods of 30-60 days and a large selection of eligible games, so you have a fair chance at cashing out your winnings.
We ensure our recommended online casinos cater to low—and high rollers. You can play at $10 deposit bonus casinos in NZ, like Wildz and Rizk, which caters to big spenders with minimum deposit bonuses up to $4,000.
Some online casinos make players wait days to receive their winnings and only payout in small amounts. We know this can be frustrating, so we’ve curated a list of the fastest withdrawal casinos with high payout limits of up to $200,000 per transaction.
Diverse and secure payment options are an important feature of online casinos, especially when specific methods aren’t eligible for promotions. Our recommended bonus casino sites offer trusted payment options, from e-wallets to credit and debit cards, bank transfers and cryptocurrency.
We prioritise online casinos that offer fair wagering contributions across a variety of games. Pokies should contribute 100%, while table games like blackjack and roulette should count for at least 8% toward wagering.
Popular payment methods at online casinos NZ
