Different Types of Online Casino Bonuses in New Zealand

Offered to players as a way to enhance their gameplay, online casino bonuses come in several forms. Here’s a quick look into some of the most common bonuses you will find at NZ dollar casinos.

First Time Deposit Bonuses

A first-time deposit bonus is a bonus offered when a player adds funds to their casino account for the first time. At most casinos, this bonus comes in the form of a match offer, free spins, or a combination of both. The amount added must match the minimum deposit required to unlock the bonus.

Online Casino Welcome Bonuses

To entice them to sign up and keep playing, online casinos offer juicy packages to new players! Most of these offers are made up of match offers, free spins, or a mix of both. Welcome bonuses always almost need a deposit to be unlocked. Exceptionally, some casinos might offer no deposit free spins or extra funds to their players as soon as they sign up.

New Casino Bonuses

New casino bonuses are exclusive offers given to new and returning players alike. These bonuses can include reload offers, cashbacks, free spins, and even match bonuses.

No Deposit Casino Bonuses

Exceptionally, you will find no deposit bonuses at some casinos. These bonuses do not need any prior deposit to be unlocked! Most times, they are offered as soon as a player signs up at a casino. However, returning players could also benefit from such bonuses. Such offers usually require no deposit bonus codes.

No deposit bonuses are mostly made up of free spins. However, some casinos could offer match bonuses as well. Make sure to read the terms and conditions carefully, however, because no deposit bonuses are often attached to high wagering requirements.

How to Use Online Casino Bonus Codes

The process to redeem the best bonus codes in NZ is easy. All you have to do is follow these quick and easy steps.

Choose Casino Bonus

Pick a bonus from the hundreds available. If you are unsure about which ones, read the terms and conditions carefully. Watch out for T&Cs such as minimum deposit, wagering requirements, expiry, and maximum win. In addition, ensure that the casino you choose to play at is licensed by a regulatory body such as the Malta Gaming Authority or the United Kingdom Gambling Commission.

Sign Up

Once you have chosen your favourite bonus, the next step would be to create an account. You can do so in these three steps:

  1. Go to your preferred casino and click on the Sign Up or Register button.
  2. Fill the form with your details (name, phone number, email address, &c).
  3. Confirm your details and create your account.

Use Bonus Code

After creating and confirming your account, you can now redeem your casino bonus code. To do this, go to the Promotions or Bonuses section and choose the bonus you would love to claim. Copy the code and paste it in the bonus code section as soon as you make your first deposit.

Alternatively, some casinos require you to redeem the bonus code as you create your account.

Start Playing

After redeeming the bonus code, you can finally start playing your favourite games! Although some bonuses are game-specific, you can use most of them to play all sorts of games.

Best Games to Play at Online Casinos in NZ

At NZ online casinos, there are thousands of games available for players to choose from, with unique features and gameplay. Choosing from these thousands can be overwhelming, so we have compiled some of the best types of games you can play, alongside some fantastic titles.

Online Poker

Online poker is one of the most popular and dramatic online casino games. A mix of strategy, luck, and skill, players have to drop or hold on to cards to get the best hand at the end of the betting rounds. Some titles you can enjoy are Deuces Wild, Jacks or Better 100 Hand and Casino Hold’em.

Online Roulette

Online roulette is the ultimate luck-based casino game. The objective of this game is to guess where the balls will land on the wheel. Players can bet on several outcomes before the (virtual) dealer spins the wheel. Some outcomes you can bet on are black or red, odd or even, and high or low. This game is straightforward and is perfect for beginners and experts alike. Some popular online roulette titles are Auto-Roulette 1, American Roulette, and Maxi Roulette.

Online Baccarat

Another interesting mix of strategy and luck, online baccarat is perfect for players who love a little more drama. Each round starts with the Player and Banker getting two cards each, and you have to bet on whose total hand value you think will be closer to 9 without going over. You can also bet on a Tie between them. Some exciting online baccarat games you can play are Punto Banco, European Baccarat, and Mini Baccarat.

Online Blackjack

Online blackjack is one of the oldest casino games, with origins from the 17th century. To win, you must have a total hand value as close to 21 without going over. Your opponent in this game is the Dealer. If your card count goes over 21, you lose automatically. Like every other casino game, online blackjack is primarily luck-based. However, you can use proven strategies to help you make the best possible moves. Some exciting blackjack titles are Single Deck Blackjack, European Blackjack Multihand, and 3d Blackjack.

Online Craps

Although online craps is one of the only casino games that uses dice instead of cards, it is just as entertaining! At the beginning of each round, you throw two dice and bet on the outcome of the throw. The three possible outcomes are natural, craps, and point. The round doesn’t end until a 7 or a point is thrown.

Casino Bonus Terms and Conditions

One thing that you should do before claiming any bonus is read the terms and conditions carefully. They are unique to every casino, no matter how similar they might seem. To make things a little clearer, we have compiled some terms and conditions you will most likely fall on.

Wagering Requirements

A wagering requirement is a multiplier that represents how much you need to bet to withdraw bonus winnings. Let’s have a look at Mr Sloty Casino’s first deposit bonus, a 400% match bonus up to $3,505 with a 50x wagering requirement. If you deposit $40, you will get an extra $160 to play with. You would have to play through $160 x 50 = $8,000 to claim your winnings.

Wagering requirements for free spins work somewhat differently as they apply to the winnings from the bonus and not the number of spins. Katsubet offers new players 100 free spins on their first deposit. These free spins are attached to a 35x wagering requirement. So, if you win $100 from these spins, you would have to play through $100 x 35 = $350.

Maximum Win

A maximum win is the highest amount you can win from a bonus. Anything above this cap will be forfeited automatically. At Katsubet Casino, the 100 free spins offered on your first deposit have a maximum cashout of $200. This cap mainly exists to make the bonus more financially viable for the casino.

Minimum Deposit

For players to redeem most bonuses, they must add a specified amount of money to their account. Bonus minimum deposits might be different from the casino’s minimum deposit amount. So, a $5 deposit casino might require you to deposit $10 to claim a bonus. For example, at Mr Sloty, you can deposit as low as $15. However, the first deposit bonus can only be claimed if you deposit at least $40.

Payment Method Restrictions

Deposits with payment methods such as Skrill, Neteller, and even Apple Pay at some casinos are not eligible to claim bonuses. This is mainly because these casino payment methods offer privacy and anonymity to players, which makes it hard for the casino to confirm the player’s identity.

Game Restrictions

At most casinos, not all games are equal. This is apparent when it comes to game restrictions. Some bonuses can only be used on specific games. In addition, not all games contribute to the wagering requirements. For example, at Gaming Club Casino, progressive jackpots, Sic Bo, Red Dog, all craps, and all baccarats do not contribute towards completing the wagering.


Bonuses do not last forever. At most casinos, if you do not claim a bonus within a particular time frame, then it will be forfeited automatically. If claimed, the bonus must be used within a specified period. In addition, you must also complete the bonus within a set time frame. If not, risk complete forfeiture. For example, at Lucky Nugget Casino, if a bonus stays unused for more than two months, then it will be forfeited to the casino.

Betting Limit

Most casinos have a limit on the amount of money you can bet per spin or round. They reserve the right to forfeit your bonus and any winnings if you go over this limit. At Katsubet, the maximum bet is $10. This amount includes double up wagers after the game round has been completed.
