The City Rail Link (CRL) is New Zealand’s largest transport infrastructure project ever.
Twin 3.45km rail tunnels up to 42m underground between Waitematā Station and Maungawhau Stations
Two new underground stations -Te Waihorotiu in midtown and Karanga-a-Hape with entrances at Mercury Lane and Beresford Square
Waitematā Station redeveloped into a two-way through station
Maungawhau Station redeveloped to include the new CRL connection and a modern station building
Wider rail network improvements including The Strand, Ōtāhuhu Henderson and Newmarket
Provision for longer nine-car electric trains
More people friendly spaces around the city.
At the end of June 2026, City Rail Link Limited achieved practical completion of the CRL Project and handed the completed infrastructure – stations and tunnels over to Auckland Transport and KiwiRail as the owners and operators. The CRL was officially opened on 11 September 2026 and services for the public began on Sunday 13 September 2026.
This City Rail Link Ltd website documents the project- as do the CRL social media pages we ran. They are Facebook, Instagram and YouTube.
