You can only make contactless transactions if you have been issued with a Multiload or MultiloadPLUS card. Single Load cards are not enabled for contactless transactions.

What do I need to know about contactless transactions?

If you have been issued a Multiload or MultiloadPLUS card, you can make contactless transactions at any MasterCard® PayPass™ participating vendor/retailer. Normally, you can make contactless transactions of up to NZ$80.00 without entering your PIN. Because of COVID-19, this has temporarily been boosted to NZ$200.00. If the transaction exceeds NZ$200.00, you will be asked to enter your PIN before the transaction is completed. Single Load cards are not enabled for contactless transactions.
