Voice calling over broadband.

Voice calling over broadband (VoIP) is the latest in phone line technology. VoIP stands for “Voice over Internet Protocol”. And VoIP replaces the old analogue voice signal with a digital signal that runs over the internet. It is only available on Fibre, HFC, VDSL, and ADSL broadband plans.

To add VoIP you will need to sign up to a broadband plan first, or call us to add it to your existing broadband plan.

Important things to know before getting voice calling

Voice calling over broadband requires power and an active One NZ broadband service in order to work. All calls will run over your broadband connection. If you have a power cut, both your broadband and phone won’t work - this includes all calls, even emergency calls to 111. We recommend always having a charged mobile phone ready to use as a backup.

If you (or someone in your household) is at particular risk of needing to call 111 emergency services for health, safety, or disability reasons, and you/that person do not have access to an alternate means of contact in the event of a power cut (for example no mobile phone) - then you can apply to be added to the 111 Vulnerable Consumer Register. If you meet the eligibility criteria, One Nz will supply you with an alternative means of contacting 111, at no cost to you. To apply for the One NZ Consumer register, visit

If you have a monitored security or medical alarm that relies on your phone line it’s important that you call the company that monitors your alarm to ask if their services will work with voice calling over broadband. If not, you’ll need to find an alternative before you move to voice calling over broadband/wireless broadband.

Handy features and call plans for your phone line

Once you’ve chosen your voice plan you can add great features to your phone line

Coming off Spark’s copper phone line service?

Spark is closing down the Public Switched Telephone Network (PSTN). Some of our One NZ customers have a phone line that runs over copper wiring, which uses Spark’s PSTN network. If you have a traditional home phone, it will stop working once Spark closes your local exchange.

To make sure our customers are up and running on more modern technology, we’ve started moving our customers off PSTN and onto alternative services like voice calling over broadband or Wireless Broadband.
