Bullock said the system would allow users to pay quickly and easily. The application doesn't need to be open to work and for purchases under $80 a PIN is not required.
"New Zealanders have a long standing affinity with electronic payments, as shown most recently by the swift uptake in contactless payments," Bullock said.
"BNZ Android Pay is just like tap and go payments with contactless cards, except you tap your phone on the EFTPOS terminal," he said. "At BNZ, we're pleased to have negotiated this technology first for our customers and look forward to [further] roll out of this in the New Year."
According to BNZ, the payment system was completely secure and Android Device Manager could be used to instantly lock the system from anywhere if the device was lost.
Android Pay was first unveiled in May 2015 and has been available in the US since September last year. New Zealand is the sixth country in the world to have the payment system.
Android Pay is currently available at retailers including The Warehouse, Noel Leeming, New World, PAK'nSAVE, Countdown, Animates, Paper Plus, Rebel Sport, Kathmandu, Farmers and JB Hi-Fi.
