Rideshare platform Ola has integrated Apple Pay as a payment method in Australia and New Zealand in what it says is the first significant overhaul of its international customer app.

Westpac and National Australia Bank customers will have to wait awhile to use Apple Pay, with both banks unwilling to give any indication when they would provide the digital payment option.

In the 12 months to January 2019, more than 1.5 million Australians used one of the latest "buy-now, pay-later" digital payment methods, with millennials making up the biggest share, according to a newly published report.
