The call

Chorus sits on regulated physical fibre that nothing digital can eat, while Starlink nibbles at its rural fringes and the Commerce Commission holds the real lever on its returns.

Chorus Limited runs the buried fiber cables that bring internet to most of New Zealand. It is hard to replace because digging up and rewiring an entire country costs billions of dollars and would take decades, plus the government says Chorus is the only real option for most areas through 2033. The real threat is Starlink satellites and Amazon's satellite internet stealing customers in rural areas where fiber is expensive to build, and eventually this could spread to towns and suburbs if those services get better and cheaper.

Why
01
AI pressure: None apparent. AI-driven data traffic pushes more demand through Chorus's pipes, feeding revenue rather than threatening the network. Could AI do the core job? Unlikely.
02
Bigger players: Starlink (SpaceX). Starlink already holds 27% of rural broadband connections and Amazon Kuiper is entering, eroding Chorus's rural edge, though urban fibre uptake keeps climbing. Could a giant copy it? No, they are blocked.
03
What protects it. A legally protected wholesale monopoly on ~NZ$6bn of buried fibre, with Commerce Commission pricing locked through 2033.
What would change this call
Amazon Kuiper begins commercial NZ service and reports rural subscriber numbers. Would show satellite competition widening beyond Starlink into Chorus's rural base.
Chorus or Commerce Commission reports satellite/FWA share of total (not just rural) connections crossing 10-15%. Would show non-fibre substitution spreading into Chorus's core urban revenue base.
Commerce Commission's Q3 FY26 WACC/capex ruling and Ispanz market study outcome (expected mid-to-late 2026). Would show whether regulation still protects Chorus's returns or starts squeezing them.
Key numbers
  • FY25 EBITDA NZ$705m (2025-06-30)
  • HY26 fibre uptake 72.4% of addresses passed (2025-12-31)
  • Regulatory asset base ~NZ$6.0bn (2025-12-31)
Named risks
  • Commerce Commission could cut allowed WACC or deregulate core Bitstream service in Q3 FY26 review. Severity: high
  • Starlink/satellite broadband crossing from rural into urban/suburban footprint. Severity: medium
  • Copper retirement execution slippage or Copper Withdrawal Code disputes through 2026-2028. Severity: medium
  • Under-earning versus allowed revenue creates wash-up volatility, NZ$101m shortfall in 2025. Severity: low

Questions people ask
Is Chorus Limited profitable in 2026?
Yes. Chorus reported HY26 net earnings of NZ$15m for the six months to 31 December 2025, a NZ$20m swing from the NZ$5m loss in HY25, driven by 7% fibre revenue growth to NZ$387m, per HY26 results published 22 February 2026.
Who owns Chorus Limited?
Chorus (NZX/ASX: CNU) is a publicly listed company with no controlling parent. As of a May 2026 filing, UniSuper Management held 18.47%, L1 Capital 6.55%, and Vanguard Group 5.47%, with the remainder widely held institutionally and via NZX-listed ETFs.
Could AI replace Chorus Limited's business?
No. Chorus's core value is buried physical fibre and copper infrastructure and a regulator-protected wholesale monopoly; the Commerce Commission declined to deregulate its core Bitstream broadband service on 31 March 2026. AI is framed by Chorus as a demand driver via rising data traffic, not a substitution threat.
Is Starlink threatening Chorus Limited's business?
Partially. A 29 June 2026 telecoms report found Starlink is now New Zealand's largest rural ISP with 27% of rural broadband connections, and Amazon Kuiper is entering as a second satellite option, but Chorus's urban/suburban fibre base, at 72.4% uptake in HY26, shows no equivalent erosion.
Who is Chorus Limited's biggest competitor?
Chorus's regulated wholesale fibre monopoly faces no direct network rival, but Starlink has taken 27% of rural broadband connections as of June 2026, and mobile operators Spark, One NZ and 2degrees push 5G fixed wireless as a substitute, per a May 2026 Flint Global report they commissioned.
Will Chorus Limited's regulated pricing change soon?
The Commerce Commission's final decision on 30 June 2026 locked Chorus's third price-quality path at five years, running 1 January 2029 to 31 December 2033, giving long-horizon regulatory certainty, though an Input Methodologies review on WACC and capex parameters remains ongoing.
