Review of Co-location on Cellular Mobile Transmission Sites
Mobile Co-location enables a Mobile Network Operator (MNO) to install mobile network transmission and reception equipment on another MNO’s tower.
At least every five years, the Commission considers whether there are reasonable grounds for commencing an investigation into whether any services should be omitted from the list of designated or specified services in Schedule 1 of the Telecommunications Act 2001 (Act).
We last reviewed Mobile Co-location in 2021, and are required to consider if there are reasonable grounds to commence an investigation by 12 May 2026.
More information including previous reviews and determinations can be found on our Mobile co-location page.
We published our draft decision paper on 23 September 2025 for consultation and published our final decision paper on 24 February 2026.
Having considered the submissions on our draft decision, our final decision under clause 1(3) of Schedule 3 of the Act is that there are reasonable grounds to commence an investigation into whether Mobile Co-location should be omitted from Schedule 1 of the Act under section 66(1)(b).
