The Plan B brand was retired on 29 July 2025. The company behind 15 Tarndale Grove in Rosedale, Auckland is now Atturra NZ Limited, incorporated in 1999 and registered under number 952616, held ultimately by Morgan Holdco after ASX-listed Atturra bought Plan B through its Cirrus Networks subsidiary for about 20 million New Zealand dollars in December 2024. Plan B ran five primary data centres across both islands at the time of the sale. Three networks are registered at Tarndale Grove - Plan B's own AS132240, ICONZ's AS4770 and Atturra Managed Services NZ's AS23838 - with no internet exchange on the floor, which separates it from the company's Tawa site, where WIX-NZ is present. Floor area and power have never been published.
Which company operates the Tarndale Grove site now?
Atturra NZ Limited, company number 952616, the renamed Plan B Limited. Atturra acquired the business through Cirrus Networks in December 2024 for about 20 million New Zealand dollars and retired the Plan B brand on 29 July 2025.
Which networks are registered at the facility?
Plan B's AS132240, Internet Company of New Zealand's AS4770 and Atturra Managed Services NZ's AS23838. There is no internet exchange on site.
How does it compare with the Tawa facility?
Tawa carries the WIX-NZ exchange and Tarndale Grove carries none. Both belonged to a five-site national network at the time of the acquisition.
What does the operator publish about the building?
Very little. No floor area, power or capacity figures appear in Atturra's material for the site.
