not bad

the app works for purpose but would be nice if it had a dark mode and more personalisation options. maybe take some tips from Westpac Australia with their app?

iPhone / Apple

My online banking app in New Zealand is Westpac. On speaking to customer Service the app should be FREE? But my Iphone8 will not allow me to download it without my bank card details which I'm trying to update with my one and only bank card (why should I need to get another bank card?) so I can transfer some money from my WP Savings Acc - my WP Day to Day Account to pay my Subscriptions or to use the funds on my Apple Account to pay for the FREE Westpac Bank Account App. When I called my banks customer service they were mift regarding this issue?! I deleted my previous WPB App because I tried to enter a Monthly Competition inside the app - when I got to the stage of entering my password and Client ID drop boxes I couldn't remember the PW so I clicked 'Forgot My Password' but due to banking app fraud - I still had to enter the PW I couldn't remember, to then be able to change the PW to a more updated one. So I closed the page and the app automatically timed me out. To use my fingerprint sign in - the app took straight back to the change your PW windows and on clicking 'Done' it would auto kick me out of the app? I repeated the last actions and was being kicked out / there was no 'back' option to fill in my details to open the transfer $$ from one WPaccount to my Day to Day acc so I'm not getting anywhere fast I haven't been able to change my PW to open my bank acc to transfer $$ to pay for my outstanding subs and or NOW my FREE? Westpac Online Banking App a vicious circle doing my head in??!! Someone HELP FFS!

No response when you want to open an account.

After update you cannot access an account, you tap and nothing happens

Freezes after log in

Every 5-6 times I log in, the app freezes and needs restarted. Very glitchy.

The App crashes

Every time I try to transfer from my account to another one of my accounts it crashes . This has been happening for over a month and I’m sick of it
