City Rail Link

The City Rail Link (CRL) is an underground rail line linking Britomart and the city centre with the existing western line near Mt Eden.

Project status: Design
Project zone: Central

Project purpose

The CRL is key to delivering the Auckland Plan, the City Centre Master Plan, the Long Term Plan and the Integrated Transport Programme.

  • Top transport priority for Auckland.
  • Auckland will grow by more than 700,000 people in the next 30 years and the CRL coupled with bus improvements is the only way to keep Auckland moving.
  • Current public transport will be unable to cater for this growth, hindering economic development.
  • The CRL will provide opportunities for development, particularly around the stations.


  • The CRL will mean more frequent trains with more direct services to the city centre.
  • Allow 30,000 people an hour in peak.
  • Allow on average better than a train every 10 minutes at peak for most Auckland stations.

  • Planning hearing concluded – NoR conditions have been confirmed subject to six appeals.
  • Property purchases started - about 50 bought.
  • Subterranean property survey has started.
  • The Principal Technical Advisor is now working on the reference design.

Project details

  • The City Rail Link (CRL) will extend Auckland’s passenger rail system past Britomart to connect to the existing regional rail network at Mt Eden.
  • Britomart will become a through station with new stations near Aotea Square and Karangahape Road, and a redeveloped station at Mount Eden.
  • The current phase is to confirm and protect a route to enable future construction.
  • The CRL will use twin 3.4km long tunnels up to 42 metres below city centre streets.
  • It’s estimated to take five and a half years to build at a cost of $2.5 billion when inflated to 2024.

Costs and funding

(As identified in Auckland Council Long Term Plan, discussions are continuing with central government).

The current cost is $2.5 billion. Auckland Council expects central government to contribute 50% of the funding.

Key facts

  • Aotea Station Artist Cross SectionTwo new underground stations at Aotea (11m depth) and K Rd (33m), and a redeveloped Mount Eden Station.
  • Cut and cover construction along Albert Street and at Eden Terrace.
  • Majority will be with tunnel boring machine (TBM).
  • 7.5metre diameter TBM (about half the size of Waterview TBM).
  • About 1million cubic meters of spoil - more than Waterview because of station excavations.
  • 88 subterranean properties affected by tunnels.
