Apple Pay is coming to New Zealand finally, but unfortunately it is only available to ANZ customers.
This feature is used by Apple iPhones, iPads and Apple Watch and you simple swipe at the machine. Security is pretty safe and simple as there is no personal data transferred over between the transaction.
Apple Pay will only be available on the iPhone 6, 6+, 6S, 6S+, SE, 7, and 7+, as well as Apple Watch and the newer iPads. Apple Watch users with older iPhones authenticate payments via a PIN rather than a thumbprint.
