Mobile Coverage - Maps

This coverage map is indicative and it's meant to give you general guidance on where our network and outdoor coverage is available.
Coverage may vary depending on your exact location, and on the type of phone or device being used.

How to get fast 5G data speeds on your phone.
To get the fast data speed of 5G, you'll 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 to get the best coverage for calling at your home or your 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.

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 on 4G, check that your phone 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).

If you have a 5G phone, you can check that it works with Band n78, which operates at the 3.5GHz frequency.
