Fibre Chorus operates an open access network to provide wholesale fibre services to phone and broadband retail providers, alongside city infrastructure such as exchanges and transport.
Ultra-fast fibre broadband initiative The ultra-fast broadband (UFB) initiative was announced in 2011 by the New Zealand government. The programme was a public-private-partnership between the then
Crown Fibre Holdings (now National Infrastructure Funding) and delivery partners, Chorus,
Northpower,
Enable, and
Tuatahi First Fibre. The initial proposal aimed to build a fibre network out to 75% of New Zealand’s population by 2019, with an investment of $1.35 billion. UFB2/2+ was announced in 2017, expanding the goal and network’s footprint to 87% of the New Zealand’s population by 2022 – 84% of which was tasked with Chorus. UFB roll out was completed in December 2022, delivering fibre broadband to 412 towns and cities.
Fibre build service agreements 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. In February 2025, Chorus Limited announced the renewal and extension of its field services agreements with long-standing partners Downer NZ and UCG, in deals collectively valued at approximately NZ$1 billion.
Copper Chorus is the owner of New Zealand’s copper network. The network can deliver broadband and phone services to customers. As of December 2024, Chorus reports around 122,000 copper lines remain active. 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. , 130,000 (7%) lines are unbundled.
Copper retirement Copper connections have been steadily decreasing since the fibre-optic network came online, with many in fibre areas choosing to move across. In November 2018, the Telecommunications act was amended, requiring the
New Zealand Commerce Commission to prepare a Copper Withdrawal Code, which came into effect on 1 March 2021. The Code had set out minimum requirements that Chorus must meet before it stops supplying copper services. An updated Code was published in February of 2024, which refined the 2021 version by streamlining notification requirements and clarifying service replacement expectations, ensuring a smoother transition for consumers as Chorus phases out copper in fibre-ready areas. In March 2021, Chorus retired a first trial batch of 28 copper cabinets, in densely populated, urban areas where the majority of customers have moved on to the fibre network. Subsequently, it announced intentions to switch off copper cabinets in accordance with the Code, and following the scheduled roll-out of the ultra-fast fibre broadband network. In 2024, Chorus reports it endeavours to retire the copper network by 2030. Consumer trends in New Zealand show a steady decline in copper network use, particularly in rural areas. A 2022
Federated Farmers survey found 23% of respondents reported declining landline service, mostly on copper, while 20% used satellite broadband and nearly a third accessed landlines via
VoIP. The 2023 Telecommunications Monitoring Report showed rural satellite connections tripled to 34,000 (14% market share), putting New Zealand at the top of the OECD for satellite use per capita. Although 97% of rural copper users are within reach of fixed wireless or WISP networks, around 2,700 remain outside coverage. Rural users reported lower broadband satisfaction (68%) compared to urban users (78%), and
Starlink speeds (184 Mbps) far outpaced other rural options. Retail copper prices were also $28 above the OECD average, driven mainly by retail rather than wholesale costs. ==History==
