Different Types of Online Casino Bonuses in New Zealand

You can find reload bonuses, cashback offers, and deposit and no deposit bonuses at NZ gaming sites. If you’re new at a casino, the following two bonus types are among the top bonuses you may want to redeem.

Welcome Bonuses

The welcome bonus is a bonus offer that is only given when a player registers at a casino for the first time. This is often a deposit bonus, and it could be in three different forms: bonus spins, match deposit, or bonus spins and match deposit. With the welcome bonus, you may get the chance to play one or several top games, usually slot machines. Depending on the casino, welcome bonuses can have a lifespan of up to 30 days. When opting for a welcome bonus, always check if a promo code is required. If there is one and you fail to use it where indicated, you’re advised to contact customer services as soon as possible before placing any bet with the qualifying deposit.

No Deposit Casino Bonuses

No-deposit bonuses are one of the best bonus types for casino players. This is mainly because such a bonus allows you to play for real money without having to spend your cash. Bonus spins are the most common form of this bonus type and when given, they are usually allocated for a specific slot game. An important thing to remember about no-deposit bonuses is that although you do not need a deposit to redeem them, you may have to deposit a certain minimum amount before withdrawing any winnings obtained. For this reason and several others, it’s always best to read the terms of use of such a bonus before claiming it.

How to Use Online Casino Bonus Codes

Here are the main steps involved in the use of casino bonus codes:

  • Visit a casino where bonus codes are used.
  • Copy the bonus code and provide it in the required field when depositing.
  • Wait for the corresponding bonus to be credited into your bonus balance.

Casino Bonus Terms & Conditions

So far, we’ve discussed different casino bonus codes and how they can be used. Now, let's take a moment to go through the elements that make up casino bonus terms and conditions.

Wagering Requirements

The wagering requirement of a bonus refers to how many times the bonus must be wagered before winnings can be withdrawn. This is sometimes referred to as the rollover or playthrough of a bonus. It can only be fulfilled when a bonus is used on games for which the bonus is destined.

Maximum Win

Real-money casino bonuses generally have a limited maximum win amount. This means that the casino will only allow you to withdraw a certain amount of bonus winnings once wagering requirements are completed.

Minimum Deposit

The minimum deposit refers to the least amount of money which a player must deposit to redeem a bonus. Minimum deposits vary from one casino to another and from one bonus to the next.

Payment Method Restrictions

Care needs to be taken when depositing to claim a casino bonus. Sometimes, payment options like Skrill and Neteller may be excluded from the list of banking options for deposit bonuses.

Game Restrictions

Generally, bonus spins will be valid on a specific game or set of games. As for bonus money, there may be a wider game variety. You must know which game restrictions apply to avoid using a bonus on games that do not contribute towards rollover.


Casino bonuses usually have an expiry date which can range from 24 hours to up to 30 days. Also, there may be a limited period during which a bonus must be activated otherwise it will be taken off your list of accessible bonuses.

Betting Limit

Maximum and minimum bet limits often apply to casino bonuses. Where such a limit is mentioned, the bonus must be used accordingly, otherwise it could affect winnings.


What is a Casino Promo Code?

A casino promo code is like a password needed to redeem a specific bonus at an online casino. The code could be a word, numbers, or a collection of letters and numbers. Where available, promo codes often serve to activate deposit bonuses.
