# Chorus Limited

Chorus is a provider of telecommunications infrastructure throughout New Zealand. It is listed on the NZX stock exchange and is in the NZX 50 Index. The company owns the majority of telephone lines and exchange equipment in New Zealand; and was responsible for building approximately 70% of the country's fibre-optic UFB network, receiving a government subsidy of $929 million to do so.
The company was split from Telecom New Zealand in 2011, as a condition of winning the majority of the contracts for the Government's Ultra-Fast Broadband Initiative. By law, it cannot sell directly to consumers, but instead provides wholesale services to retailers.

## Products
### Copper

Most of the telephone infrastructure in New Zealand is owned by Chorus. As of January 2014, Chorus can provide ADSL service to 97.3% and VDSL2 (up to 70/10 Mbit/s) service to 62.4% of its copper phone lines.
Contrary to the standard overseas practice of providing full-speed Fibre, Chorus plans differ in the amount of data and speed allocated. As DSL is sensitive to distance, the closer the customer is to the equipment, the faster the connections. Chorus has implemented a fibre-to-the-node (also known as "cabinetisation") project to bring the equipment closer to the user, so 91% of the lines are able to access an ADSL2+ connection of 10 Mbit/s or more.
The copper loop is unbundled, so operators like Vodafone and Vocus can install their own equipment at telephone exchanges and just rent the copper line from Chorus. As of December 2013, 130,000 (7%) lines are unbundled.

### Fibre

Chorus has the task of installing the majority of the New Zealand government's ultra-fast broadband (UFB) fibre. The Ultra-Fast Broadband: Invitation to Participate in Partner Selection Process was issued by the Ministry of Economic Development in October 2009, detailing 75% of New Zealanders to be connected over 10 years, with priority broadband users such as businesses, schools and health services to claim focus for the first six years.
In April 2013, Chorus signed contracts with Visionstream and Downer worth NZ$1 billion to build its part of New Zealand's ultra-fast broadband network, after receiving a government subsidy of $929 million. Early in 2014 Transfield Services signed agreements to help build the UFB network. The fibre network footprint was extended twice, with the build work completed by late 2022.

## History

Telecom created Chorus as a separate business unit in 2008. In 2011, Chorus won most of the contracts for the UFB fibre network. A condition of the contracts is that Chorus be demerged into a separate company. This was recommended unanimously by the Telecom board of directors and approved by 99.8% of Telecom shareholders.
On December 1, 2011, Chorus was formally separated from Telecom and listed on NZX. Chorus got Telecom's copper lines, cabinets, most telephone exchange buildings, DSLAMs and some fibre back-haul. Telecom retained the relationship with retail customers, the POTS telephone exchange equipment, some fibre back-haul, the shares in Southern Cross cable and the XT mobile network. On August 8, 2014, Telecom was rebranded as Spark.
The company is part of New Zealand Telecommunications Forum.
