Bringing electric trains to Pukekohe
The Government granted $419 million to extend the electrification of Auckland’s metro rail network from Papakura to Pukekohe. This means people travelling from Pukekohe now no longer need to switch trains at Papakura and can enjoy faster, quieter and cleaner journeys in modern electric trains.
By encouraging people to use public transport rather than private vehicles, electrifying more of the network will reduce carbon emissions.
The project has:
- extended the overhead power system from Papakura to Pukekohe
- upgraded the existing track, signals and level crossings across this 19km section of the Southern Line
- redeveloped Pukekohe Station.
Electrifying the line
To electrify the railway, we have installed Overhead Line Equipment (OLE) alongside and above the existing track.
From Pukekohe to Papakura over 800 mast structures, including 472 masts and 381 bridges/ booms, have been installed to support close to 130km of overhead electric line to power electric trains.
The final OLE installation and energisation was completed during the 2024 Matariki weekend network closure and since then, the first electric test train has travelled down to Pukekohe Station.
The line was officially reopened for passenger trains in February 2025
The Rail Network Rebuild (RNR) teams also carried out crucial work on the same section of the Southern Line while the line was closed. This work will improve reliability and enable more frequent trains across Auckland.
Stay safe, stay away
There are many benefits to electrification of the track, but overhead electric lines carry 25,000 volts of electricity - this is 100 times more powerful than the electricity in your home.
Electricity can arc (jump) across gaps or pass through objects and water. If you come too close, or touch these lines, it will cause serious injury or death.
Never try to touch the lines, throw anything at them or dangle items from bridges above them.
If you have children, make them aware of the dangers. Never play with kites, balloons or other high reaching items near overhead lines.
A height restriction of 5 meters is now in place at all level crossings and is clearly signposted. Motorists in vehicles or towing loads that exceed these restrictions should choose an alternative route or contact us on 04 474 2323 for advice.
If you live next to the rail tracks:
- Be aware of your distance from the lines if you are working at your property boundary. Always keep at least a 4 metre distance.
- Be careful when water blasting at your boundary – direct the water down.
You may require a KiwiRail permit if:
- You want to trim a tree on your property and are concerned it may come into contact with the lines or infrastructure.
- You want to construct scaffold within 8 metres of the lines.
- If you plan to use machinery with moving parts and might encroach on the minimum 4 metre distance.

Redeveloping Pukekohe Station
KiwiRail worked closely with Auckland Transport to build a modern public transport interchange in Pukekohe.
To make room for the modern passenger facilities, the original Pukekohe Railway Station building was moved to Matangi, near Hamilton, where it will be restored and become part of a historic precinct.
A new platform layout was built to accommodate longer trains. These platforms currently serve six-car trains with an option to extend them to nine-car trains in the future.
New structures have been installed to support the overhead lines and the track layout has been changed to allow for trains to pass easily and safely through the station area.
A new stabling yard has also been built for the new electric trains.
