Important things to know
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.
Consumer terms and Wireless Broadband terms apply.

Wireless Broadband FAQs
How do I get 5G Broadband?
When will 5G Broadband be available in my area?
We cannot guarantee dates of when 5G will be rolled out to specific areas, but will provide updates throughout the 5G rollout when possible.
How do I set up my 5G Broadband modem?
If you have 4G Broadband and are upgrading to 5G Broadband, head to one.nz/4Gto5G and let our chatbot Hana know you have your new modem. Once we hear from you, we’ll turn off your old 4G modem and will switch you over to 5G Broadband. It’s normally instant, but it can take up to 30 minutes to change over. Make sure you use the new SIM card provided with your 5G modem – your old 4G SIM card won’t work with the new device. If you don’t already have 4G Broadband, you can skip this step.
If you have a TP-Link Deco X80-5G modem, follow the below steps to set up:
- Plug the provided power plug into your X-80 modem.
- Wait for the light on your modem to either turn solid green (4G) or purple (5G). You are now connected to the internet.
- Your Wifi username and password is located at the bottom of your modem. Or, on a Wifi sticker in the modem box. Use these details to connect your devices to your Wifi.
Tip: To maximise your performance, it’s a good idea to place your modem out in an open space, high away from obstacles. Try testing a few locations in your house to help find the best spot.
If you already have the TP-Link Deco app installed from setting up SuperWifi, you will need to reset your network to make the Deco X80-5G the master device:
- Tap on the globe icon at the top of the app’s home screen, click the three dots and delete the network.
- Your SuperWifi units will then start flashing blue – we recommend unplugging them until it’s time to add them back into your new network.
- Follow the in app prompts to set up your new Deco X80-5G modem.
- Once your new network is up and running, you can add your SuperWifi units to the network.
If you have a Huawei H122 5G modem, follow the below steps to set up:
- Plug your modem into a power plug – the best place for a strong connection is near a window.
- When the 5G light on the front turns on, you’re connected to our 5G network. A green light means you have a strong connection, a yellow light means moderate and a red light means there’s a weak connection. If needed, move your modem to get a better signal strength, such as trying window on the other side of the house or ensuring it’s not covered by anything.
- Use the Wifi Name and Wifi Password on the sticker on the bottom of the modem to connect your devices.
