The first thing to know when considering bonus codes in New Zealand is that they are the same as promotional codes. If you are looking to get something for free in the online casino world then bonus codes are the way to go. Bonus codes are usually included in sign-up offers or deposit bonuses. They are also sometimes offered as special “rewards” in loyalty programs. Some will require players to enter a code when they sign up while others will automatically trigger when the player deposits an amount of money.
