Chorus is a state-shaped infrastructure monopoly built from a 2011 demerger. It controls the physical layer of New Zealand’s internet — but not the customer relationship, pricing, or service design. Its success is measured in coverage and uptake, not profit per user or innovation. It works because regulation forces openness — not because it competes.
Chorus owns most of New Zealand’s telephone lines, exchange equipment, and built most of the UFB fibre network.

The written brief1 min read
What the company or idea is
Chorus Limited is New Zealand’s largest telecommunications infrastructure company, formed in 2011 when Telecom New Zealand demerged its network assets.
How it actually makes money
Chorus makes money by selling wholesale access to its fibre and copper networks to retail providers. It cannot sell directly to consumers. Its revenue comes from fees charged to retailers for using its infrastructure.
What works
Its open-access fibre network covers 87% of New Zealanders as of 2024, with 75% uptake. It delivers the majority of the Ultra-Fast Broadband (UFB) network built under the 2011 public-private partnership.
What does not
Its copper network is being retired by 2030, yet still supports 122,000 lines as of December 2024. This creates stranded cost pressure with no offsetting revenue growth path beyond fibre uptake.
What to take from it
Chorus shows how a legally mandated wholesale-only model can scale national fibre coverage (87% population) while locking in structural dependency on retail partners — not consumer demand.
Is it worth your time
Yes — if you are studying how state-backed infrastructure monopolies operate under regulated open-access rules in small, high-cost markets.
