Currently One is promoting its New Zealand Satellite service, which allows you to send text messages anywhere across the country, even if there’s no mobile phone coverage.
However, while such a service could be the difference between life and death for adventurers and residents in remote regions, and provide back-up in the event of a natural disaster, NZ’s fixed mobile towers remain the backbone of the country’s mobile network.
NZ’s Mobile Coverage
There are three main mobile networks in the country, which were built by 2degrees, Spark and One (formerly Vodafone). Although 2degrees and Spark have since their tower assets, they still use the networks they built.
In major centres, there’s very little difference between the three networks. However, in rural and remote areas coverage can vary dramatically. And then there’s 5G, which is more limited in its reach, even in major centres.
But across 5G, 4G, 3G and even 2G, which provider offers the best mobile coverage in your region? Search by region below, or read on for a full rundown of which providers offer the best mobile coverage.
North Island
North Island Regions
Northland
- 2degrees: Excellent coverage through its 4G and 3G boosted networks. Few areas are impacted, with fair coverage in most rural areas. The only notable blackspots are extremely remote regions, such as the Puketi and Warawara Forests, and sections along 90-mile Beach and Cape Reinga.
- 5G: Limited 5G coverage in and around Whangārei, Kerikeri and Kaitaia.
- One: Good coverage through its 3G and 4G networks. Black spots include Puketi and Warawara Forests, and sections along 90-mile Beach and Cape Reinga.
- 5G: One has several small pockets in and around Taipa, Kaitaia, Kerikeri, Kaikohe, Ruatangata, Whakapara, Waipapa, Whangārei and along State Highway 1 around Ruakākā and Kaiwaka.
- Spark: Fair coverage in populated regions but limited elsewhere. Blackspots across Cape Reinga, Herekino, Waipoua, Taipuha, Tutamoe Range, Warawara Forest, and along 90-mile Beach.
- 5G: Spark has 5G coverage in Pukenui, Mangōnui, Kerikeri, Kaikohe, Dargaville, Whangārei and Mangawhai.
Auckland
- 2degrees: Excellent coverage across the region. While coverage in the Waitākere and Hunua Ranges is limited, it’s more extensive than Spark and One’s coverage.
- 5G: Most of central Auckland is well covered, including central suburbs like Newmarket, Remuera and Greenlane. Coverage follows State Highway 1 from Northcote and Takapuna in the north to Papatoetoe, Manurewa and Papakura in the south. 2degrees also has coverage out west, from Waitakere down to New Lynn, plus extensive 5G at Auckland Airport.
- One: Excellent coverage across the region. Notable black spots in the Waitākere and Hunua Ranges, but good coverage across Rangitoto and Motutapu Island.
- 5G: One’s 5G network is widespread in Auckland, although patchy. It’s concentrated in built-up areas, so while you can expect it to work throughout the wider Auckland region, you can also expect it to dip in and out as you move about. Notably, One’s 5G coverage stretches from Warkworth and Orewa in the north to Drury and Pukekohe in the south, and from Henderson in the west to Howick and Beachlands in the east.
- Spark: Excellent coverage across its 4G network. However, some black spots in the Waitākere and Hunua Ranges.
- 5G: Spark has pockets of 5G mobile coverage across Auckland. Its 5G coverage is centered on downtown Auckland, but spreads out along major arterial roads, south to Tuakau, north to Sunnynook and east and west to Botany Downs and Kumeū, respectively.

Which provider has the best mobile coverage?
For general coverage
If you’re in a populated area, then all providers should offer plenty of coverage, as nearly every main urban area in the country is covered. While it can look like much of the country is without reliable mobile coverage (which is in many ways true) it’s important to note these areas are usually extremely remote. For example, 2degrees claims that its mobile network covers 98.5% of the places Kiwis work and live. And the other networks aren’t too far behind.
As mentioned above, 2degrees has the widest coverage and may be suitable for those in remote regions or who enjoy frequent visits to national parks, forests and hiking spots.
For 5G
For those who crave 5G, One currently has the widest coverage. Not only does it do a fairly good job at covering main urban areas, but it has coverage across many small residential areas, towns, and tourist hotspots.
But all three providers plan to continue rolling out 5G across the country. As shown above, both Spark and One offer 5G in widely different places. And the largest areas of each region aren’t always first to receive 5G. For example, One has 5G in Motueka but not Nelson, while Spark offers it in Clyde and Alexandra but not Queenstown.
So if 5G is important to you, it pays to check providers’ websites to see if 5G is available where you live.
