Chorus is New Zealand’s biggest fixed-line communications infrastructure entity, and was demerged in 2011 from Telecom New Zealand. Chorus offers wholesale access to its nationwide copper and fiber network to retail service providers. It also provides backhaul services to retail service providers and connects mobile phone towers. At the end of 2022, Chorus completed the government's rollout of ultra-fast broadband, or UFB, a fiber-to-the-premises network to cover 87% of the population in New Zealand.
