Switching to One NZ from another network? You will need a new One NZ SIM card but we will send you a new SIM card with your new plan.
Before you swap SIM cards...
Back up your contacts, TXTs and any other data saved on your old SIM card to your phone's memory, otherwise these will not be available using your new SIM card.
- Find out how to back up your mobile using our Device Guides >

- Move your number onto a new SIM by visiting any of our One NZ retail stores .
