As a consumer you can change service providers but retain your landline phone number, to take advantage of the best deals available.

To port a number, contact the provider you wish to change to and tell them you want to port your number. Porting should take one business working day for mobile phones or up to three days for landlines.

There is no fee to port your number, however there may be outstanding payments due or a charge for breaking a contractual term.

Number porting means you can no longer rely on a phone number to indicate a specific calling area, for example, (09) 620 XXXX previously assigned to Mt Eden, could now be on the North Shore or South Auckland.
Number portability does not allow you to keep your fixed landline number if you move outside your local calling area. For example, if you move from Wellington (area code 04) to Christchurch (area code 03) it is not possible to port your Wellington number. You will be assigned a new number.

Did you know?

Both landline and mobile phone numbers are allocated under a ‘license to use’. This means you can port your number when you change providers, but it is not your property and it is not possible to buy or sell phone numbers.

The Number Administration Deed (NAD) is responsible for the New Zealand Telecommunications Numbering Plan. It is made up of the Number Allocation Rules and the Number Register.
