Wellington,In a major push toward sustainable mobility, New Zealand has announced the launch of its first battery-electric train fleet, set to transform regional rail services across the Lower North Island.

The $802.9 million initiative will introduce 18 battery electric multiple unit (BEMU) trains, designed to operate on both electrified and non-electrified tracks. Manufactured by French rail company Alstom, the fleet will serve the Wairarapa and Manawatū lines, replacing aging diesel locomotives and significantly reducing emissions.

Officials say the new trains will cut travel time between Wellington and Masterton by up to 15 minutes, while doubling peak-hour services and expanding off peak and weekend options. The project is jointly funded by the central government (90%) and regional councils, with Alstom contracted to maintain the fleet for 35 years.

Named Tūhono a te reo Māori word meaning “to connect or unite” the fleet symbolizes a new era of cleaner, quieter, and more inclusive transport for regional communities. Service rollout is expected by 2030.
