Our 2G and 3G networks will shut down from end of December 2025 to enable faster 4G and 5G connectivity. Check how to stay connected.
One Smart Network. It’s here to keep you connected.
Over the past few years, the world has changed how we live, work, play and connect.
So we’ve built a faster, safer, more secure and resilient mobile network for Aotearoa.
We are also proud to be awarded the best mobile network in Aotearoa for the fourth year running, independently tested by global leader in mobile benchmarking, umlaut, part of Accenture, in May 2025.
umlaut offers a more robust and reliable assessment of mobile networks, compared to others that simply rely on user-generated data.

Frequently asked questions - Mobile Networks
What mobile network awards has One New Zealand won?
One NZ has been recognised independently for its network performance.
In 2025, One NZ was named “Best in Test” mobile network for the fourth consecutive year by umlaut (part of Accenture). The benchmark included on-the-ground drive testing and crowd-sourced data across urban, regional and rural areas.
For this award, One NZ achieved a score of 852/1000 in the 2025 results, compared to 787 for the next best provider. One NZ also won Best in Voice Services and Data services as well as Best in Reliability.
See Reseller News article about this network award.
In earlier years (2022, 2023, 2024) similar awards were won across Best in Test, Best in Data and Best in Reliability; a clean sweep of award categories out performing Spark and 2Degrees.
These accolades serve as independent validation of the network experience we are delivering across voice, data, coverage and reliability as well as sustainability.

What is One New Zealand's coverage like in rural areas?
Rural coverage is a key focus for One NZ, both in terms of conventional mobile coverage and with next-generation satellite-enabled coverage.
One NZ delivers 4G and 5G mobile coverage to most of where Kiwis live, work and play (98.5% of those areas and approximately 60% of New Zealand’s geography) and have tools to check coverage at a specific address.
We participate in the government-led Rural Connectivity Group (RCG) infrastructure build-out (alongside other providers) to extend mobile broadband/wireless in rural NZ.
With our One NZ Satellite service in partnership with SpaceX/Starlink, we can reach places outside cell-tower coverage (e.g., remote farm, mountain, water) where traditional mobile signals are weak or absent with line of sight to the sky.
And we cover offshore/coastal zones: one of our public statements notes “up to 85 nautical miles off the coast” via satellite-powered coverage in addition to our 4G network.
So One NZ is delivering best-in-class rural reach, and the satellite mobile offering adds a new layer of reliability and connectivity in remote settings.

Spark NZ say they have the best coverage in Aotearoa, as determined by Open Signal. What’s the difference between Umlaut and Opensignal's research?
In New Zealand, there are multiple independent benchmarking organisations (including umlaut and Opensignal) that evaluate mobile networks, but they use different methodologies and metrics.
Here's a breakdown:
umlaut (Accenture): Their "Best in Test" reports combine drive-testing across urban, regional and rural areas with crowd-sourced data over a defined period. Tests cover voice call setup, data performance (web browsing, file downloads, streaming), and reliability (ability to stay connected). Example: In 2025 One NZ scored 852/1000 and led on voice, data and reliability.
OOKLA: They publish market reports every 6 months based on Crowd source data as well. One.NZ does very well there OOKLA Market Report.
Even though One NZ does well in other industry reports, only umlaut results are published due to the comprehensive focus on accuracy in benchmarking, as is seen across their use over 120 markets globally. umlaut embrace extensive drive testing (comparing operators side by side using the same high capability device at the same location at the same time) together with Crowd Source data to give a comprehensive Overall score outcome.

In an international context, how does One NZ compare? Is it world-class?
Yes, One NZ is delivering performance that matches or outpaces many international operators. For example:
- According to the Ookla Speedtest Connectivity Score for NZ in January-June 2025, One NZ recorded 74.58, highest among NZ mobile providers. Ookla
- Our independent audits (umlaut) show scores in the 800+ out of 1000 range for NZ market, a very strong result compared to global benchmarks. Umlaut (part of Accenture) class any network >850 in the very Good Category. Media - Mobile Network - One NZ; International Scoring in 2025
- The satellite mobile innovation (direct-to-cell via SpaceX) is cutting-edge internationally (few operators globally currently deploy it). Gadget Review
