Types of Online Casino Bonuses

New Zealand online casino bonuses come in all shapes and sizes, with some suiting specific players more than others. To give you a better idea of which casino bonus to claim, we’ve outlined the most popular promo types below:

Welcome Bonus

Welcome Bonus

A welcome bonus will likely be the first promo you encounter at an online casino. This offer is only available to new players, and it’s designed to capture your attention and encourage you to sign up and deposit. Common welcome bonuses include deposit matches, free spins or a combination of the two.

Free Spins Bonus

Free Spins Bonus

As the name implies, free spins bonuses give you the chance to spin the reels of online pokies without risking your hard-earned cash. You may need to make a deposit to claim the free spins, but you won’t need to stake any of your funds to play. Free spins bonuses can be attached to welcome bonuses or standalone offers. For instance, popular NZ casino SpinBet offers 100 free spins as part of its sign-up offer, which can be used on selected slots.

No Deposit Bonus

No Deposit Bonus

No deposit casino bonuses in NZ are exactly as they sound – they reward players with small perks like free spins or bonus funds with no deposit required, but you can still win real money from them. For example, top-rated NZ casino, Wheelz, regularly rewards no deposit free spins simply for being an active player or as part of a promotional offer. While they’re highly sought after, be aware that no deposit bonuses often come with hefty wagering requirements, e.g. 50x or higher.

No Wagering Bonus

No Wagering Bonus

No wagering casino bonuses are any type of promotion that doesn’t have wagering requirements attached. Therefore, you won’t need to play through your deposit amount or bonus funds before you’re able to withdraw your winnings.

Match Deposit Bonus

Match Deposit Bonus

With a match deposit bonus, a New Zealand online casino will match a percentage of your deposit up to a specific amount. For example, Royal Vegas rewards all new users with a 100% deposit match up to $300 over your four deposits. So, if you deposit the full $300 as part of your first deposit, you’ll receive an extra $300 in bonus funds, giving you $600 to play with in total.

Reload Bonus

Reload Bonus

Reload promotions are available to existing players who have an account and make a deposit during the promotional period for the offer. They can come in many varieties, including bonus funds, free spins, cashback and more. They’re a great way for you to continue getting bonuses once you’ve used the welcome offer.

Minimum Deposit Bonus

Minimum Deposit Bonus

Excluding no deposit casino bonuses, all NZ promotions require a minimum deposit. Minimum deposit casinos cater to players on smaller budgets by offering lower-than-average deposit requirements, typically ranging between $1 and $10. For example, Kiwi’s Treasure has a 50 free spins welcome offer, which requires just a $1 minimum deposit to claim.

New Casino Bonus

New Casino Bonus

New casino bonuses are available at the latest online gambling sites. Since these new casino platforms want to attract as many players as possible and persuade them to make deposits, they often provide bigger rewards and more generous casino bonuses.

Mobile Casino Bonus

Mobile Casino Bonus

Some New Zealand online casinos may provide exclusive promotions to players who download, register and deposit via their mobile casino sites or dedicated apps for iOS and Android. These offers can come in many different forms, including deposit matches, free spins, no deposit bonuses, and more.

Cashback Bonus

Cashback Bonus

Consider casino cashback bonuses your safety net. Essentially, these offers are rebates on your casino losses over a specific period of time. Cashback promotions soften the blow of losses and allow you to claim back and continue playing with cashback bonus funds.

Low Wagering Casino Bonus

Low Wagering Casino Bonus

Low wagering casino bonuses simply refer to promotions that have lower-than-average playthrough requirements. The industry average for online casino bonuses is 35x to 40x. Therefore, offers with wagering requirements of 20x or lower are considered low wagering casino bonuses.

Special Casino Promotions

Special Casino Promotions

From time to time, New Zealand online casinos may offer special casino bonuses to players who meet specific criteria, such as those who enter exclusive casino bonus codes or reach a certain level in a casino’s VIP or loyalty programme.


What’s the Best Casino Bonus in NZ?

Casino bonuses are a great way to boost your bankroll and are one of the main advantages of gambling online instead of at a retail casino. They come in many forms, from deposit matches to free pokie spins and cashback.

The best online casino bonuses will depend on your game preferences as a player. For example, table game bettors will benefit more from bonus funds, while free spins are perfect for pokie players.

Bonus Type How the Bonus Works Why You Should Claim
💰 Welcome/Sign-up Bonus New players claim a bonus after creating an account and depositing for the first time. You can explore a new casino and its offerings with a boosted bankroll.
🎁 No Deposit Bonus Access to bonus funds, credits or free spins with no deposit required and still be in with a chance of winning real money. Test out games without spending a cent.
🪙 Minimum Deposit Bonus The bonus requires a minimum deposit (e.g. $10) to trigger it. Minimum deposits can cater to players of all budgets, but are great for those with limited funds or if you’re looking to try a new casino with limited risk.
🎰 Free Spins Bonus You can get a certain number of spins on pokies that don’t require you to wager money. Explore new pokies, experiment with variance and test out new slots features.
🤑 Reload Bonus Designed for existing players who have already created a casino account and deposited funds. Examples include deposit match, free spins, weekly reload and no wagering reload bonuses. Keep taking advantage of bonuses beyond the new player welcome offer.

What Are Casino Bonus Codes?

Casino bonus codes are unique digital keys that unlock bonuses and promotions. They usually consist of a sequence of numbers and letters that relate to the value of the bonus.

For example, to fully activate Let’s Lucky’s deposit welcome bonus, you’ll need the bonus codes ‘LUCKY2’, ‘LUCKY3’ and ‘LUCKY4’. Note that not every bonus requires a promo code.

How to Find the Best Casino Bonus

The real value of a bonus doesn’t lie in the number of free spins you get, or the amount offered in deposit matches, but in the terms and conditions. It’s essential to check for the following T&Cs before committing to a bonus, as they can impact the amount you can win.

  • Fair wagering requirements
  • Long validity
  • Reasonable max win caps
  • Eligible payment methods
  • Few restricted games

Online Casino Bonus T&Cs

Before opting into a casino bonus, you’ll need to pay attention to the terms and conditions, which can affect how you use and withdraw your bonus funds. Check out the most common bonus rules and restrictions below.

  • Wagering requirements are the number of times you must play through your bonus funds and/or deposit amount before you can withdraw your winnings as cash. Almost every bonus has them, and the industry average is 35x to 40x, so anything within that range or below should be achievable.

  • If your bonus does have high wagering requirements, you want to make sure you have enough time to complete it. This period differs between casinos, with some bonuses expiring after a month and others expiring after just seven days. You should also take note of how long you have to claim the offer (i.e. make a deposit).

  • Many casinos exclude certain games from their bonuses. For example, certain table games, progressive jackpots and live casino games typically don’t contribute towards wagering requirements as they have low house edges/high RTPs. However, the best welcome bonus casinos allow you to wager your bonus on table games, albeit for a lower contribution (around 10%). Some casinos may also offer exclusive live dealer welcome bonuses, but these often come with high minimum deposits.

  • Nobody wants to win a $500 jackpot only to discover that bonus winnings are capped at $50. Win caps can be a set limit (such as $100) or multiplier (like 10x your deposit amount), so keep an eye out for both.

  • Bonuses have minimum deposit requirements that players must meet in order to claim them. Budget-friendly sites often have minimum deposits as low as $5 or $10, while others might require deposits of $30 or more.

  • Some payment methods, particularly e-wallets like Neteller and Skrill, are excluded from certain bonuses. The majority of casinos let you claim bonuses using whichever method you prefer, but it’s worth checking the T&Cs first.

How We Rate and Review Online Casinos

We have a thorough review process that helps us make the most informed casino recommendations possible. Our experts leave no stone unturned, examining the bonuses, payment options, security, casino games, software, mobile capabilities and customer support offered by each casino.

How We Rate and Review Online Casinos

Safety and Security

Your safety is our principal concern. We check for evidence of licensing from a reputable regulatory body like the Malta Gaming Authority (MGA) and the Alderney Gambling Control Commission (AGCC). This licence proves the casino meets strict player safety and fair gaming requirements.

Bonuses and Promos

Every player loves a bankroll boost, so we make sure bonuses are fair and worth claiming. We scrutinise the wagering requirements, expiry dates, eligible games and excluded payments to ensure they’re fair and reasonable. We rate casinos that offer generous deposit match welcome offers with fair playthrough requirements (35x-40x), along with other rewarding promos including free spins, cashback and loyalty programmes.

Games and Software

Quantity doesn’t guarantee quality. We’re not looking for a massive games library, but a diverse selection of pokies, table games and live dealer titles from leading software developers, including Apricot (formerly Microgaming), NetEnt, Pragmatic Play and Evolution.

Mobile Experience

Every casino should be built on HTML5 technology to ensure a seamless transition from desktop to mobile. We also love seeing compatible mobile casino apps for iOS and/or Android devices which provide a more bespoke mobile gaming experience.

Payment Methods

Between credit and debit cards, e-wallets, bank transfers, eChecks and crypto, there are many different ways to deposit and withdraw at online casinos. For a casino to get a top recommendation, we need to see at least one option for each category. We also expect the best NZ casinos to boast fast withdrawal processing times (ideally within 24 hours) and no transaction fees.

Customer Support

Customer support is one factor that often goes unnoticed, but can make or break the user experience when you need it. We want to see detailed FAQs and round-the-clock support via live chat, email, phone and social media.

Frequently Asked Questions
