One NZ will never ask for your passwords or banking PIN, or ask you to screen share or give remote access to your device. If something sent you looking for this number, that message was the scam.

Check your account and bills there, not through a link.
Type it yourself. Never follow a link in a message.
Walk in and ask, with your ID.
Yes. It's One NZ's mobile support number, listed on One NZ's own contact page. But a caller showing this number may still be a scammer, because caller ID can be faked. Hang up and call it yourself.
Hang up. In One NZ's words: "One NZ will never contact you unexpectedly to ask for sensitive information, including full credit card details, one-time PINs, or to complete biometric verification over the phone."
That's a scam. One NZ says: "We will never ask you to screen share or give remote access to your device". Hang up and call One NZ yourself.
Someone may be trying to get into your account. Don't share any code with anyone. Contact One NZ yourself so they can check your account.
Disconnect the device from the internet. From another phone, call your bank, then One NZ, and change your passwords. Then go to What to do now.
