Find out all you need to know about our phone line plans
Whether you are a long distance dialler or just keen for a quick catch-up, you can do this from the comfort of your home with one of our phone line plans. You'll need to have a broadband plan with us in order to take up this calling service.
Voice calling over broadband
Voice calling over broadband (VoIP) is the latest in phone line technology. VoIP stands for “Voice over Internet Protocol”. It 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.
Voice calling over wireless broadband
Our Wireless Home Phone plan is delivered over our mobile network. You can keep the same number and access all your favourite phone features like voice mail and call waiting.
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 one.nz/vulnerability
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
Our phone line features are billed on a monthly basis from the time the features are added on your account. If you want to cancel any of your phone line features, we'll credit you back for any paid in advance charges. To buy any of these additional features you need to have a One NZ home phone service with One NZ.
Why not use your mobile instead of a 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.
