What is a casino bonus?
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 VIP offers.
The welcome bonus is the most common offer at an online casino and is exclusive to new players. These rewards typically comprise a percentage match of your first deposit (ranging between 50% and 200%) and/or a specific number of free spins. No deposit bonuses are another popular offer and allow players to gamble without spending their own money.
Types of online casino bonuses
NZ online casinos provide several casino bonuses to attract new players and retain existing players. Besides welcome bonuses, Kiwi players can claim high roller, live dealer and even mobile casino bonuses.
Welcome bonuses are widely available at NZ online casinos. In most cases, you’ll need to register a new account and deposit cash to qualify for the offer, which usually includes free spins and/or bonus funds. For example, For example, one of our top-rated operators, Rizk, offers new players a 100% match up to $4,000 and 50 free spins on Gates of Rizk when they sign up.
Free spins are a highly sought-after bonus that you can use 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 can also be awarded free spins at a no deposit bonus casino by simply signing up to play, allowing players to gamble risk-free.
While not as common as welcome bonuses, this is one of the best offers available at NZ casinos. No deposit casino bonuses allow you to play casino games risk-free, as you aren’t required to put your own money on the line. Many no deposit bonus casino sites offer no deposit casino bonus codes for existing players, while new players will need to register an account first.
High roller casino bonuses are designed for players with larger budgets. They’re usually obtained through a tier system, where players accumulate points by depositing and wagering large amounts, so you won’t find high roller casino no deposit bonuses. Join Rizk and reap the benefits of its high roller programme, which includes rewards like luxury vacation packages.
This only applies to live dealer games. Previously, these were hard to come by, largely because these games have higher RTPs and are more expensive to produce, but the rise in immersive gaming has increased the demand for live casino bonuses. They’re often offered as part of Drops & Wins promos, for instance at 22Bet, where you can win a share of $500,000 every month.
This is another rare type of promotion where players receive bonus funds or free spins without any wagering requirements. You can therefore withdraw your winnings immediately without needing to bet or play through a specific amount first. Alternatively, you may also find low wagering casino bonuses, which come with minimal playthrough requirements.
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 up to $400 on your first deposit and up to $300 on your second and third.
How to calculate an online casino bonus
Casino bonuses are typically expressed as a percentage of your deposit. The percentage, which usually ranges between 50% and 200%, refers to how much of your deposit you’ll get back as bonus funds to play with.
For instance, a 100% deposit match bonus means if you deposit $100, you receive an additional $100 in bonus funds.
Many online casino bonuses 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. In this instance, the maximum amount you can claim is $1,000.
Here are some examples of bonus percentages to illustrate how they work:
Bonus percentage | Deposit amount | Bonus funds |
---|---|---|
50% | $100 | $50 |
75% | $100 | $75 |
100% | $100 | $100 |
150% | $100 | $150 |
200% | $100 | $200 |
New casino bonuses for NZ players
If you want to increase your bankroll, a new casino is your best bet. Newer gambling platforms typically offer bigger welcome bonuses to incentivise new players to join their growing platform. Other promotions you’ll find at new casinos include reload bonuses, reward multipliers, giveaways and referral bonuses.
Several new casinos spring up yearly, so we regularly review, test and list only the best of the bunch. For instance, Mirax Casino, founded in 2022, is one of our top-rated new gambling sites in NZ, offering a host of lucrative promotions including no deposit bonus codes, match deposits, crypto bonuses, free spins and reload offers. Sign up and you can claim generous offers such as 10% cashback when you spend NZ$400 as a high roller Kiwi player.
Bonuses for existing players
Existing players can take advantage of numerous promotions to increase their bankroll, including loyalty bonuses, VIP schemes, and more. Here are the most common bonuses for existing players:
Loyalty programmes: The best online casinos have a rewards programme that awards players’ points depending on how much they bet. The VIP scheme also gives loyal customers free spins, VIP event access, exclusive bonuses and cash prizes as they advance through the ranks.
Referral bonuses: Players can enjoy exclusive bonuses for successfully inviting family and friends to register and gamble at a casino site. This is usually a match bonus, increasing your deposit by a percentage.
Reload bonuses: As the name implies, reload bonuses are issued when you deposit more money into your betting account.
Cashback: This is an incentive programme where online casinos return a percentage of your spent funds into your account.
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 wagering requirements. Casinos like JackpotCity and Spin Casino are great sign-up bonus casinos.
Read the casino's T&Cs
Each online casino has different bonus rules. Before depositing and committing real money, you should carefully read the T&Cs.
Deposit real money or sign up
Register an account or make a qualifying deposit to activate the offer. Remember, some real money casinos also require a bonus code to award funds.
Meet the playthrough requirements
Most online casinos have specific requirements you need to meet before gaining access to your winnings, such as wagering conditions and time limits.
Withdraw your winnings
This is entirely optional. After meeting the requirements, you can now access your winnings and withdraw as real cash or continue playing.
What are casino bonus codes?
Casino bonus codes are special promotional codes that you’re required to enter to claim a specific offer. Bonus codes can be associated with various types of promotions, such as welcome offers, free spins, reload bonuses and no deposit bonuses.
Sometimes, bonus codes are linked to exclusive offers or promotions that aren’t available to all players, so if you don’t have the code, you won’t be able to claim the offer.
Be aware that bonus codes may have expiry dates or specific eligibility criteria, such as being a new player at a casino.
For example, Mirax Casino is currently offering new Kiwi players who sign up 35 free spins on the pokie, Wild Lucky Chance, with the no deposit bonus code ‘35WILD’. Visit our no deposit bonuses guide for more information.
Casino bonuses T&Cs 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:
A wagering requirement is the number of times you must bet bonus funds before withdrawing them from your betting account. Winning and losing betting rounds are counted toward the playthrough requirements.
Most sign-up bonus casinos have a 30x to 50x wagering requirement, which is in line with the industry standard, while anything over 50x is considered a high wagering requirement. There are some casinos that allow players to withdraw funds for even less than the standard.
Most online casinos require you to deposit a minimum amount to activate the bonus. You’ll find $1 deposit bonus casinos in NZ, alongside platforms that require up to $10, $20 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 offers players a 100% match bonus up to $1,000.
Another widespread practice at most NZ gambling sites is bonus time limits. Players are given a time limit to fulfil the conditions outlined in the T&Cs, usually ranging between seven and 30 days. If you fail to meet the requirements within the time limit, this will cost you your bonus funds.
Your welcome bonus may not be eligible for use on your chosen casino’s entire game portfolio. It's also important to note that games have different contributions towards meeting the wagering requirements. For instance, pokies may contribute 100% to the requirement, while table games contribute 15%. Some online pokies may also be off limits primarily due to their high return to player (RTP) percentage.
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, so be sure the read the T&Cs carefully before you commit.
Popular payment methods at online casinos NZ
Crypto casino bonuses
Some gambling platforms only accept crypto and Bitcoin payments and, as a result, offer players bonuses when you deposit using this method. You can receive generous rewards when you deposit with Bitcoin and other digital currencies at crypto casinos.
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 bonuses, these are hard to come by in New Zealand.
Mobile casino bonuses
You can take advantage of 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 mobile-exclusive bonuses, targeting Kiwi players who prefer to gamble on the go. Operators like Betway also have dedicated mobile casino apps, available on iPhone and Android devices, to make mobile gambling even more convenient.
Many operators also offer mobile-friendly payments such as Apple and Google Pay, making claiming bonuses and depositing and withdrawing money even more seamless, as everything can be managed from your mobile device.
