Download Weekly: 3G shutdown begins in Dunedin
Carrier's share remains stable
In its latest report, Telcowatch says One New Zealand was the leading mobile service provider in fourth quarter of 2025 in terms of market share. One NZ has a 36% share of the market.
While this puts One NZ well ahead of second-place Spark (32% market share), Telcowatch regards Spark’s budget-price Skinny brand as a separate entity.
Skinny has a 6% market share. If this is combined with Spark’s 32%, then Spark remains the overall market leader with a 38% share. This would be the market share metric that matters in telco boardrooms. It also makes sense as Skinny is now closely integrated with the rest of Spark.
Meanwhile, more than three years after 2degrees merged with Orcon, the business has 26% of the market.
This tells us New Zealand’s mobile phone market has been stable for a long time. Six years ago in the January 2020 Telcowatch report, Spark combined with Skinny commanded a 41% market share.
One NZ, then known as Vodafone, was on 36%, the same as today. Likewise Skinny was on 6% then and now. 2degrees was on 23%. Over the long haul 2degrees has won 3% of market share from Spark’s main brand.
New Zealand's mobile market has been remarkably stable since 2014

One NZ: 3G network shutdown starts in Dunedin
One New Zealand has begun shutting down its 3G mobile and moving customers on to 4G and 5G services. The company says the switch off started earlier this week in the Dunedin region where the 3G network shutdown on Tuesday January 20.
Kieran Byrne, chief technology officer, says last year One NZ completed 258 mobile upgrades in anticipation of the 3G shutdown. Every One NZ site is now equipped with 4G, many have 5G.
While closing the 3G network represents progress, it remains controversial. Last July the Digital Equity Coalition Aotearoa identified risks associated with the shutdown, including a general lack of awareness about the move.

Nokia and Connexa partner to streamline network operations
A deal with Nokia means Connexa is the first mobile tower operator to outsource its network operations to a third-party service provider rather than managing them in-house or through traditional channels.
The move will see Connexa consolidate its operations from multiple local providers. The goal is to simplify operations, improve efficiency and give customers better network availability.
Connexa will use Nokia’s expertise, tools and practices in network operations automation. CEO Rob Berrill says Nokia will help Connexa better manage its distributed tower network – over 2,500 sites (and counting) across Aotearoa New Zealand.
