North Island Rail Connection

Description

The Lower North Island Rail Integrated Mobility (LNIRIM) programme is delivering a transformative upgrade to regional rail services. At its heart is Tūhono – a fleet of 18 five-car battery-electric multiple unit (BEMU) trains, the first of their kind in the Southern Hemisphere.

Tūhono, meaning “to connect” or “to unite,” symbolises regional connection and improved access for the communities they serve. It tells the story of a train that is more than just a mode of transport — it is a living thread that weaves together the diverse communities of the lower North Island.

Designed for New Zealand’s unique rail conditions, Tūhono trains will operate on both electrified and non-electrified tracks, switching seamlessly to battery power where needed. This innovation will support more frequent, reliable, and sustainable services across the Wairarapa and Manawatū lines, connecting communities from Masterton and Palmerston North to Wellington from 2030.

The programme also includes significant infrastructure improvements, such as upgraded stations, new stabling yards, and passing loops to support the expanded fleet and timetable.

Partnerships

Metlink is working with Horizons Regional Council and KiwiRail on this project. Built and maintained by Alstom and co-funded by Greater Wellington, Horizons and the Government.

Updates

Alstom awarded the contract to design, build and maintain the Tūhono fleet for 35 years.

Procurement process is underway.

Benefits

Greater connectivity between urban centres and regional communities.
Doubling of peak-time services on both the Wairarapa and Manawatū lines.
Reduced emissions and congestion through battery-electric technology.
Improved passenger experience with inclusive design: wheelchair access, bike and pram spaces, accessible toilets, vending machines, and water dispensers.
Culturally enriched design, featuring livery created by Māori-owned Indigenous Design & Innovation.

Customer Impact

Passengers can expect:

More frequent services during peak and off-peak times.
Shorter journey times thanks to infrastructure upgrades and modern train technology.
Enhanced comfort and accessibility on board.

These changes will make public transport a more attractive option for commuting, education, and leisure, while supporting regional growth and sustainability goals.
