Commission recommends removing outdated mobile tower-sharing rules

The Commerce Commission has recommended removing outdated mobile tower-sharing rules that are no longer needed, after mobile operators sold their towers to specialist tower companies.

Published 27 October 2026

The Commission’s review found that tower companies and mobile operators are negotiating access without regulatory intervention, and that regulation is no longer needed to support competition.

Telecommunications Commissioner Tristan Gilbertson says the industry has fundamentally changed since the rules were introduced in 2001.

“When mobile operators owned the towers, they had little incentive to give competitors access. The rules addressed that risk by allowing operators to use a competitor’s tower rather than building their own.

“Spark, One NZ and 2degrees have since sold their tower infrastructure to specialist tower companies. These companies make money by attracting multiple tenants onto their towers, giving them a strong commercial reason to support sharing,” says Mr Gilbertson

The existing rules apply to mobile network operators, not the specialist companies that now own the towers. They therefore provide no effective regulatory backstop.

“We found no significant barriers preventing access to mobile towers. Tower companies have strong commercial incentives to attract existing operators and new entrants.”

“Removing the rules would better reflect how the market has operated since mobile operators sold their towers three years ago. During that time, tower access arrangements have been negotiated commercially without regulatory intervention.

“It will also ensure that the benefits of competitive access continue flowing through to consumers,” Mr Gilbertson says

The Commission will continue to monitor access and competition. If new competition concerns emerge in the future, it is able to investigate and recommend appropriate regulatory intervention.

The Commission has provided its recommendation to the Minister for Media and Communications, who will decide whether to remove the rules.

Background

What is mobile co-location?

Mobile co-location allows mobile operators to install their own network equipment on a shared tower. It reduces the need to build separate towers, helping lower the cost of expanding mobile networks.

Why was it regulated?

The Telecommunications Act 2001 regulated mobile co-location to support competition by giving mobile operators access to their competitors’ towers. The regulation supported 2degrees’ entry into the mobile market and the expansion of existing networks.

What has changed?

Spark, One NZ and 2degrees have sold their tower infrastructure to specialist tower companies, Connexa and Fortysouth. These companies do not operate mobile networks and fall outside the existing regulation. Their business model relies on attracting multiple tenants onto their towers.

What happens next?

The Minister for Media and Communications will consider the Commission’s recommendation. The rules will remain in place unless the Minister removes them from the Act.

The Commission’s final report is available.
