Auckland Metro Rail Programme

Aucklanders and visitors make more than 21 million commuter rail journeys on the network in Auckland each year. The network also carries freight traffic that supports national freight supply chains, including to and from the country’s two biggest ports (Ports of Auckland and Port of Tauranga).

KiwiRail and Auckland Transport are working with Waka Kotahi NZ Transport Agency to improve passenger and inter-regional freight services.

We are working to build a network that is resilient and easily maintained, allows for more reliable passenger and freight services, and future-proofs Auckland for further demand. 

The Government has provided funding of almost $1 billion for a suite of projects to support growth. These upgrades will ease congestion on the busiest parts of the network between central Auckland and Wiri, extend the electrified rail network from Papakura to Pukekohe, add new stations at Drury, and bring the overall network up to a modern standard.

Key current projects 

Track replacement work

Recent testing across the Auckland metro network has indicated wear on the tracks is more widespread, with repair work required more urgently, than previously understood. We are accelerating our programme to replace the most worn sections of rail and resurface less damaged sections. More information can be found here

Wiri to Quay Park ‘Third Main’

Designed to ease congestion and improve connectivity on the busiest parts of Auckland's (and New Zealand's) rail network, building the third main is a series of projects to improve the metro network. Works are planned for Westfield and Wiri junctions, Middlemore to Wiri and in the Quay Park (Ports of Auckland) and began in late 2020. More information can be found here

Papakura to Pukekohe Electrification

Enabling commuters to have a seamless ride from Pukekohe to the rest of Auckland, extending electrification of the region's rail network will see electric trains replace diesel trains. Works to install new overhead wire and signaling systems and necessary station changes and began in late 2020. More information can be found here

Supporting City Rail Link

Providing a better connection between the West and central city, KiwiRail is working to ready the region's rail network for the City Rail Link (CRL) which opens in 2024. We're undertaking several projects to do this. More information can be found here.

Managing Rail Service Growth

Bringing the existing Network up to standard will see increasingly levels of general rail construction activity around the region. This work is preparing for increasing the improved service frequency expected after the City Rail Link opens. It includes renewing rail tracks, which includes new formation, drainage, sleepers and rails. 

To keep the network running smoothly as more trains increasingly use it also requires both increased coordination between train operators and more power. We are working with our key project partners to plan improvements to ensure these changing needs are provided for.

Being good neighbours

CRL 960x540

We’re mindful of how work affects our neighbours and we strive to finish projects as quickly and efficiently as possible.

We always try to do as much of the work during weekday hours as possible. At times work is required when trains are not running (at night or during weekends and on public holidays) this allows us to reduce the amount of overall disruption.
