Rural addresses are specifically excluded. If you live in a rural area, please see our rural broadband plans.

You can make unlimited national calls for an additional $10. (Up to 7 days to connect phone service)

Services that require a fixed line phone line to work, such as monitored home alarms, medical alarms, faxes, the interactive features of SKY digital or PABXs may be incompatible with our calling service. One NZ recommend checking with the provider of any existing fixed line dependant services.

Using your home phone

• If power is not available then broadband, and any services which run over it including calling from your home phone (and calls to emergency services), may stop working unless there is battery backup at your place.
• Once your broadband is connected you’ll need to plug your home phone directly into your One NZ supplied modem instead of the wall phone jack. Non-One NZ modems will not work.
• Making phone calls – you’ll now need to dial the area code before dialing the phone number, eg 09, 07, 03 etc. There may be a delay of up to 10 secs before it starts ringing. You can reduce this by pressing * when you dial.

Early Termination

• If your Broadband service ends for any reason you must return the modem in good working condition with cables and accessories within 30 days of notifying us of your intention to terminate.

One NZ's Consumer terms and Broadband & Home Phone Terms apply.

You need to sign up to a 5G Broadband plan, be within a 5G coverage area and be using the One NZ 5G modem. 5G is available in many areas, and we continue to roll out 5G to more New Zealanders so keep an eye out on our 5G coverage map.

5G is live in parts of Auckland, Wellington, Christchurch, Tauranga, Whangarei, Hamilton, Queenstown, Rotorua, Whakatane, Foxton, Kaikoura, Rolleston, Ashburton, Alexandra, Gore, and more.

We cannot guarantee dates of when 5G will be rolled out to specific areas, but will provide updates throughout the 5G rollout when possible.

One NZ’s landline service runs over broadband and relies on power in your home to operate. This means that if there is a power cut in your home, your broadband and phone will not work, and you will not be able to call 111 emergency services on your landline (unless you have a backup power source). Some devices, such as home or medical alarms, may also not work during a power cut if they do not have an inbuilt battery. It's a good idea to always have a charged mobile phone handy or to prepare an alternative power source such as a generator or battery.

If you can show that you, or someone in your household, are more likely than other consumers to require the 111 emergency service, and have no alternative means to contact 111 at the premises, we will provide you with a means to contact 111 in a power cut, free of charge. For more details on our obligations under the Commerce Commission’s 111 Contact Code, eligibility criteria and how to apply to register as a vulnerable customer, visit one.nz/vulnerability or call us on 0800 438 448 (between 8am-7pm, Monday to Friday). Our website also contains information about how to make a complaint relating to the 111 Contact Code.
