Use mobile payment at a supermarket and get $20 cash back. First time user only, no minimum spend. New World, Pak'n'Save, Countdown, Four Square, Fresh Choice or Farro only.
edit: applied for the card yesterday and it appeared in my internet banking app today. Can then add it to Google Pay. Quick and easy. It seems you can't apply for a ASB card if you're already a customer though during lockdown.
Rip, I used this for the first time a month ago so now I'm not eligible
