Check your coverage


This coverage map is indicative and is intended to provide general guidance on where the One NZ network and outdoor coverage is available. Coverage may vary depending on your exact location and the type of device being used.

How do I get 5G data speeds on my phone?

To get the fast data speed of 5G, you need to be in an area with 5G coverage, have a 5G phone with 5G activated, or use a 5G modem from One NZ.

How do I get the best voice calling quality on my phone?

VoLTE technology enables voice calling on 4G and 5G phones using our 4G network. When you start using a VoLTE-capable phone, you'll notice the amazing call quality, fewer dropped calls, and quick call setup times.

To use VoLTE, you'll need a VoLTE-capable mobile phone. This may also require a software update to enable VoLTE on your phone. See our list of VoLTE-capable phones to learn more and understand what to expect with software updates.

How do I get the best coverage at my home or work?

Wifi calling is similar to VoLTE and works over any reliable Wifi connection. It’s great at home, work, or anywhere else where coverage may not be ideal. To find out more, check out Wifi calling.

Does your phone work on the One NZ network?

To ensure the best network experience, it's crucial that your phone is fully compatible with our network. This is especially important if your phone or device was purchased overseas, through an international website, or from a parallel importer who may not have verified its compatibility with New Zealand's mobile networks. For optimal performance, please check that your device supports the following 4G bands:

  • 4G Band 1 (LTE 2100MHz)
  • 4G Band 3 (LTE 1800MHz)
  • 4G Band 7 (LTE 2600MHz)
  • 4G Band 8 (LTE 900MHz)
  • 4G Band 28 (LTE 700MHz)

What's our coverage?

2G 3G-coverage
4G and 5G Coverage
Our 4G and 5G network connects more than 99% of the population and delivers a great experience with data on speed and connectivity, and voice quality with VoLTE. By late 2024 we’ll have rolled out 4G or 5G everywhere we currently have 3G and we’ll start to switch off the 3G network. There's plenty of time to make the move over to 4G or 5G.
Coverage solutions
Starlink
We're very proud to collaborate with SpaceX to provide Starlink satellite to mobile service. When the service goes live, there will be a satellite to mobile service for far greater coverage than available now. We will launch with a TXT service by the end of 2024, with data and voice to follow in 2025. (Capacity management and fair use may apply).
4G Coverage
One Pin
We want all of Aotearoa to feel connected. That's why we spend over $100,000,000 upgrading more than 300 sites each year. But there's nothing quite like hearing real feedback, so we're asking kiwis to tell us exactly where they're experiencing dropped calls, slow speeds or simply don't have connectivity at all.

Drop a pin and help us create a more connected Aotearoa at onepin.one.nz/.

Coverage solutions with WiFi Calling
Voice over WiFi
With Wifi Calling it’s easy to make and receive calls and texts in any location covered by WiFi across NZ or overseas, even when you have a weak or no mobile signal. ​

It works like a normal call, plus there’s no additional charge for One NZ customers as it will come out of your plan’s minutes.​
