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 dialling 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.

Wireless Broadband FAQs

How do I get 5G Broadband?

You'll need to sign up to a 5G Broadband plan, be in a 5G coverage area and be using the One NZ 5G Broadband modem.
Remember that 5G is live in selected areas in a range of towns and cities, and we continue to roll out 5G to more New Zealanders. So keep an eye out on our 5G coverage map.

When will 5G Broadband be available in my area?

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 we will provide updates throughout the 5G rollout, when possible.

How do I set up my 5G Broadband modem?

If you ordered 5G Broadband online or over the phone, you’ll get sent a SIM card as well as a modem. Just slide the SIM card provided into the slot of the bottom of your new 5G modem – it will click into place when inserted the correct way around. If you bought a 5G modem from one of our stores, the SIM card will already be inserted for you.

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:

  1. Plug the provided power plug into your X-80 modem.
  2. Wait for the light on your modem to either turn solid green (4G) or purple (5G). You are now connected to the internet.
  3. 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:

  1. Tap on the globe icon at the top of the app’s home screen, click the three dots and delete the network.
  2. Your SuperWifi units will then start flashing blue – we recommend unplugging them until it’s time to add them back into your new network.
  3. Follow the in app prompts to set up your new Deco X80-5G modem.
  4. 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:

  1. Plug your modem into a power plug – the best place for a strong connection is near a window.
  2. When the 5G light on the front turns on, you’re connected to our superfast 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.
  3. Use the WiFi Name and WiFi Password on the sticker on the bottom of the modem to connect your devices.

If you need help setting up call us on 0800 800 966.

How do I set up my new 4G modem?

    1. Plug the provided power plug into your X-58 modem.
    2. Wait for the light on your modem to turn solid green. You are now connected to the internet.
    3. 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.

    How do I choose my own WiFi password?

    To change the network name and password on a TP-Link Deco modem, follow the below steps:

    If you haven’t already, download the TP-Link Deco app and follow the simple in app instructions to finish setting up your new modem and WiFi network – make sure you select the correct modem type in the app.

    Note, you may need to unplug the modem and begin the modem setup again.

    Download the app here:

    Google Play Apple App Store

    1. Open the TP-Link Deco app.
    2. Click on the ‘more’ icon on the bottom right of the home screen.
    3. Select the WiFi icon and change the network name (SSID) and password within the app.

    To change your network name and password on a Huawei modem, follow the below steps:

    1. Connect a device to WiFi using the network name (SSID) and password on the bottom of the modem.
    2. Open a new browser on this device and go to 192.168.1.1 – the login screen will then be displayed.
    3. Log in using the password on the bottom of the modem, which is printed under the IP address. If you have updated this password previously, then use the password you created.
    4. Click on the WiFi Settings tab – the WiFi Basic Settings screen will then appear.
    5. Select the WiFi name (SSID) field, click edit and then enter the new name for your WiFi.
    6. In the WiFi password section, enter the new password for your Wifi.
    7. We recommend that the 5GHz preferred is selected – this means that both the 2.4 and 5Ghz WiFi bands use the same Wifi name and password.
    8. Click save at the bottom of the page.

    If you need help setting up call us on 0800 800 966.

    How do I set up my new home phones?

    1. Pop the batteries into each phone.
    2. Plug the larger base unit into the back of your new modem and into a power plug – no phone jack required.
    3. Plug the smaller base unit into any power socket – it's a spare phone for you to have anywhere you’d like in your home.

    Making phone calls – you’ll now need to dial the area code before dialling the phone number, eg 09, 07, 03 etc.

    If you need help setting up call us on 0800 800 966.

    Is 5G safe to use?

    Yes, 5G is safe. The Ministry of Health and World Health Organisation offer factual information on their website.

    Are there any services I can't use with Wireless Broadband?

    • If you have a monitored home alarm or medical alarm, it’s really important that you call your alarm provider to find out if it’s compatible with Wireless Broadband.
    • Other services that can’t be used with Wireless Broadband are: EFTPOS machines that require a landline, faxes, multi line, static IP and ISDN/PBXs.

    What is the 111 Contact Code?

    The Commerce Commission's 111 Contact Code (“111 Code”) was created to ensure that Vulnerable Consumers have reasonable access to an appropriate means of calling 111 emergency services in the event of a power failure.

    Newer home phone services such as voice calling over broadband, which rely on an active working broadband service, won’t work in the event of a power failure, without an independent power source. The 111 Code requires Telecommunication Service Providers to provide Vulnerable Consumers with an alternative solution to contact 111 in an emergency.
    If you are receiving One NZ household voice calling over broadband services over Fibre, HFC, VDSL, ADSL or Wireless technology and you, or someone you live with, do not have access to a traditional copper phone line, and is likely to need to contact 111 for health, safety or disability reasons and, you do not have the means to do so during a power failure, please read the information below and fill out a Vulnerable Consumers Application form.

    If you qualify, One NZ will provide you with an alternative means of contacting 111 in the event of a power failure, free of charge.

    How can I keep track of my Wireless Broadband data?

    The best place to track how much data you’re using, buy extra data or pay your bill is in the My One NZ app. If you haven’t yet, download the app today from www.one.nz/app and follow the steps to get set up. If your Wireless Broadband isn’t showing in your app, you can add it in – you’ll just need to use your new One NZ account number and 4-digit PIN.
