ASB executive general manager of digital data and brand, Simon Tong, said the bank decided to join Apple Pay now to give customers the most options for simple and easy payments, along with existing offerings.
To enrol in Apple Pay, customers need a suitable Apple device and an ASB credit or debit card.
Apple Pay is highly integrated with the American company's devices and software, using Touch ID and Face ID authentication for easy yet secure payments online.
Joining Apple Pay does not mean ASB will ditch its existing payment solutions which Tong said includes PayTag, Garmin Pay, FitBit Pay, online EFTPOS as well as direct to mobile from the bank's mobile app, and the Virtual app for Android devices.
"It is our aim is to give our customers the greatest flexibility possible. ASB is more than happy with the uptake of our contactless mobile payments particularly as adoption has increased over the last 24 months." Tong said.
We'll continue to review our mobile payments suite to make sure we respond to customer demand as new solutions emerge in the market."
Tong declined to reveal how much it has to pay Apple for the payments system, and the share of transaction charges the bank will get.
