Current Projects

City Rail Link Enabling – Britomart

City Rail Link Enabling – Britomart

Remodelling of Britomart Tunnel layout in preparation and to enable the City Rail Link works.

Wiri to Quay Park Third Main

Wiri to Quay Park Third Main

Westfield and Wiri are the busiest junctions on the rail network for both freight and commuter trains. The works will improve the way the junctions connect between the rail yards, EMU depot and the main line. Constructing an additional track through this area and improving the junctions between the Manukau Line, Ports of Auckland Inland Port, Auckland Transport’s EMU Depot, and the Southern Line will help to separate freight and commuter trains.

Trentham to Upper Hutt

Trentham to Upper Hutt

The rail line between Trentham and Upper Hutt will be double tracked to create two lines so trains can travel in both directions at once. Signalling upgrades are being implemented for the existing line in addition to the new signalling installed on the second line.

Papakura to Pukekohe

Papakura to Pukekohe

The extension of the current Auckland electrified network from Papakura to Pukekohe requires re-signalling and system upgrades. New signalling will be installed to improve safety, resilience and ensure compatibility with the new overhead power system.

City Rail Link

City Rail Link

The City Rail Link (CRL) is NZ’s largest transport infrastructure project ever. It is a 3.45km twin-tunnel underground rail link up to 42 metres below the Auckland city centre. It will transform the downtown Britomart Transport Centre into a two-way through-station that better connects the Auckland rail network and it allows the rail network to at least double rail capacity.
