Customers reported that they were unable to log into their online banking services and the ANZ app as of at least 11:30 a.m. today.
The technical issue was then resolved a few hours later at 3:30 p.m., the bank said on social media.
“The ANZ app and internet banking are now working,” the bank said.
“Thank you for your patience and we are sorry for the inconvenience caused.
“If you are still having trouble accessing the ANZ app, please force close and reopen the app.
“If the problems persist, please let us know.”
An ANZ spokesperson previously said the bank has a team of experts working to rectify the technical fault as a “top priority.”
“We are doing everything we can to restore these systems as soon as possible,” he said.
“We apologize for the inconvenience caused to our customers.
“Customers can still access funds through ATMs, eftpos and Apple Pay.”
The technical issue arises after customers were unable to make payments for several hours yesterday due to an outage.
“We are aware of an issue affecting the ability to make Pay ID payments through Internet Banking and the ANZ app,” the company explained on Twitter and Facebook yesterday.
Frustrated customers responded that the problem was “not good enough”, sharing their difficulties caused by the outage.
A woman wrote that she was unable to pay for her groceries at the supermarket yesterday and another customer had to pay for her groceries.
