Britomart Station is currently the city centre terminus of AT's train services. Construction is underway to connect the station to the new City Rail Link tunnels.
Project Status: Under Construction
Project Zone: Central

Since 2015, construction on the new City Rail Link has been taking place in or around Britomart Station. This includes building tunnels underneath the Chief Post Office, the main entrance to the station, and along Albert Street.
The work in the Chief Post Office was completed in early 2021, and we welcomed customers back inside the building for the first time in four years.
There is still more work that needs to be done to future proof Britomart Station. That way, it will be ready for the increased number of travellers arriving at this station once the City Rail Link is complete.
Britomart is currently a terminating station. This means that trains arriving from around Auckland stop at the station and must return the way they came from. This can create delays or disruptions if one train is late or if there is a failure of any sort.
From now until 2024, City Rail Link and their contractors will be making changes to the track and platform layout to convert Britomart into a two-way through station.
The two outside platforms at Britomart (currently known as Platforms 1 and 5) need to be connected to the City Rail Link tunnels that now sit underneath the Chief Post Office. The number of platforms inside the station will also reduce from five to four. Two of these will connect to the new tunnels, while the other two will still terminate at Britomart.
Inside Britomart Tunnel, which connects the station to ground level, the track layout will need to be reconfigured and the platforms extended. There will also be construction to move underground equipment rooms that keep the station operating.
Once this work is complete, we'll be able to operate faster and more frequent services - up to 24 trains per hour - when the City Rail Link opens. This will give Aucklanders more options for travelling through our city by train.
Construction works carried out by City Rail Link and their contractors are mostly limited to existing underground rail infrastructure. This means that their impact on project neighbours is mostly limited to discrete locations.
We expect some above-ground work to impact project neighbours. This includes the enabling works for the relocation and realignment of the tunnel wall, which will take place inside a discrete footprint within the eastern footpath of Britomart Place.
As there will permanently be one fewer platform inside Britomart Station once these works finish, AT Metro services will be affected. The first change will affect Onehunga Line services.
From Monday 27 June, Onehunga Line services will start and finish at Newmarket Station.
Onehunga Line services will continue to operate on a 30-minute frequency to and from Newmarket Station, and will continue to be a limited stop service during peak travel hours.
Customers travelling from Onehunga towards Britomart will be able to make easy and frequent transfers to Southern Line or Western Line services at Newmarket Station.
Both lines have enough capacity for transiting passengers and operate at a 10-minute frequency during peak hours.
Once the City Rail Link opens, there will be changes to services and timetables across the AT Metro rail network and the enhanced public transport network. These changes will make the most out of our investment in rail.
Journey options during the service changes
The changes to Onehunga Line services mean that you might experience a change to your journey.
