We continue to upgrade our digital infrastructure to bring more 5G technology to areas where New Zealanders live, work and play. In fact, One NZ just agreed to acquire Dense Air's NZ business to add radio spectrum for 5G.

Plus, One NZ was awarded the best mobile network in Aotearoa New Zealand again, independently tested by global leader in mobile benchmarking, umlaut, part of Accenture, in May 2023.

What makes 5G better?

5G is a mobile network that's faster, smarter and more reliable in every way.

Increased network capacity

5G has greater capacity for volume of traffic. This means staying connected, at higher speeds, even in a crowd.

It's faster

5G has faster upload and faster download speeds compared to 4G. It provides more real time connectivity and massive productivity benefits.

Lower network latency

5G has a shorter delay to access content you are downloading, providing benefits for entertainment, education, and making it exceptionally responsive for your business applications.

The Benefits of 5G

The fifth generation (5G) of mobile networks enables faster speeds, lower latency (lag), and expands the potential of connected phones and devices. 5G offers a massive leap forward in speed, reliability, and connectivity.

The benefits of 5G are wide-ranging including expanding options for working on-the-move, streaming in HD even while on-the-move, powering better esports and gaming, offering greater Internet of Things capabilities, for example smart watches connecting to smart phones and controlling smart home devices like heating, lighting and security and use in manufacturing, farming and more.

5G can help foster greater digital inclusion by enabling community benefits like improved health, education, and better social outcomes. In time, you’ll also see the effects of the 5G network make even more exciting things come to life.

Frequently asked questions

What is 5G?

5G is the fifth-generation technology for mobile networks.
A 5G network is smarter, more consistent and more reliable in every way. It is faster, has lower latency, offers more connectivity and has larger capacity. That means it enables better connectivity for how we live, work and play as well as better connectivity with the rest of the world.
Using 5G is worth it just for the speed improvements alone.

How can I access 5G?

You will need a 5G phone from One NZ, a 5G ready plan (all 4G capable plans) and be in a 5G coverage area. Ensure that 5G is enabled in your settings.

5G is now available in select NZ cities, as we continue to expand and roll out 5G to even more towns and cities. So keep an eye on our 5G coverage map to see where you can get 5G.

How much will I pay for 5G?

There is currently no additional cost for 5G mobile plans. If you are looking for a 5G Wireless Broadband plan for your home see our Wireless plans or our Wireless plans for Business.

How much data will I use on 5G? Do I need to be on a plan with unlimited data?

With much faster speeds, you may use more data on 5G, especially for video applications such as Netflix or Youtube as higher video resolutions could result. If you are on a capped plan, we recommend you upgrade to a plan with unlimited data, so that you don’t run out of data.

Can I use a 5G phone that was bought outside of New Zealand or parallel imported, to access One NZ’s 5G network?

We cannot guarantee that overseas/parallel imported phones will work on the One NZ 5G network. We recommend that you buy a One NZ approved 5G phone from One NZ or other selected retailers. One NZ-approved handsets are fully tested and compatible with the full suite of One NZ services and frequencies. This benefit includes the benefit of having support of VoLTE.

What does latency mean, and why does 5G reduce latency?

We experience latency as responsiveness. For example, after entering a web address, does the page load straight away or are you left drumming your fingers? On a network with lower latency like 5G, content could load in just a few milliseconds.

How do 4G and 5G work together?

Due to mobility management and 4G/5G carrier aggregation features, our customers will move seamlessly between 4G or 5G coverage.

Can I use 5G when I am roaming overseas?

Yes, you can roam with 5G. 5G is now available in selected countries when traveling overseas. Find out what countries are 5G enabled.

Is 5G safe to use?

Yes, 5G is safe. The Ministry of Health and the World Health Organisation offer factual information on their websites. Over 30 years of research has been done on the effects of radio waves from mobile phones and there are no known negative health impacts.
