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 overview

The CRL is the key project in an integrated transport programme to keep Auckland moving as the city grows by more than 700,000 people during the next 30 years.

The CRL completes a “missing link” in Auckland’s transport system, benefiting all of Auckland. By getting rid of the dead end at Britomart and joining the rail network through the city to the west, it allows a train about every seven to 10 minutes from most Auckland stations.

An independent study, produced in collaboration with central government, shows the CRL, combined with bus improvements, is the only way to meet transport demand for the city centre within the next 30 years.

Te Reo Māori and NZ Sign Language translations of the video are available.


  • A train every five to 10 minutes at peak for most stations;
  • Quicker travel and better access to more parts of the city centre with three new stations;
  • More people on trains will free up roads for those who need them;
  • More road space for buses for parts of Auckland not served by rail, such as the North Shore. Without the CRL major bus routes will be at or over capacity in 2021;
  • The only transport option to keep speeds on city centre roads from dropping to 7km/h by 2021;
  • Drives economic growth with more high productivity jobs in the city centre by creating better access;
  • Makes future expansion of the rail network to the North Shore, via Wynyard Quarter, and the airport possible.
