Rail in New Zealand

The railway runs through the length of the New Zealand, from north of Whangarei as far as Bluff in the south.

There are over 4,000 kilometres of track and over 3,000 level crossings.

KiwiRail is responsible for freight operations on the rail network, manages the movement of all trains (passenger and freight) and is also responsible for managing the infrastructure, including rails, bridges and level crossings. There are also level crossings on non-KiwiRail lines, such as those operated by the Taieri Gorge or Glenbrook Railways.

Urban Passenger Trains


Each week KiwiRail (under the Tranz Metro brand) operates 2,200 suburban passenger services in Wellington under contract to Greater Wellington Regional Council.

In 2010/11 a significant amount of investment went into the Wellington rail network.  KiwiRail has extended the double tracks from McKay’s Crossing to Waikanae on the Kapiti Coast.

Other projects, such as an upgrade of the Johnsonville line and a new line into Wellington Station were also undertaken to improve the reliability of Wellington’s passenger services.

Greater Wellington Regional Council has also purchased 48 new Matangi trains from Korea which are being progressively introduced into service.


In Auckland, Transdev Auckland operates passenger rail services under contract to Auckland Transport, delivering more than 2,100 train services a week and 11 million passenger journeys each year.

A programme of modernisation has been in progress since late 2006 which culminates in the arrival of new electric trains from April 2014.

The electrification of the Auckland network will see 80kms of the rail corridor being electrified from Papakura in the south to Swanson in the west, and including the Onehunga and Manukau branch lines.

An ongoing public awareness and education campaign is underway to ensure Aucklanders are alert to the safety risks associated with electrification, including faster, quieter trains and electrified overhead wires which, at 25kv, are 100 times more powerful than the power supplied to a typical house.

More information about electrification and the associated safety risks is available here.

Other improvements aimed at improving reliability, frequency and comfort in recent years have included complete resignalling of the network, station upgrades at Newmarket, Panmure, Mt Albert and New Lynn, double-tracking of the Western Line, and newly introduced Onehunga Line and Manukau Line .

Long Distance Passenger Trains

KiwiRail Scenic Journeys also operates four long-distance passenger trains:

  • the Northern Explorer (Wellington to Auckland),
  • the Tranz Alpine (Christchurch to Greymouth),
  • the Coastal Pacific (Christchurch to Picton), and
  • the Capital Connection (Wellington to Palmerston North).

Freight Trains

Every week over 900 freight trains move around the country, transporting general freight and goods such as coal, milk and dairy products, wood and timber products, iron, steel and meat. 

A report by the Ministry of Transport in 2009 forecast overall freight volumes to rise by 75 percent over the next 20 years.

Changes in use of lines

The Onehunga Branch Line was brought back into use for passenger trains in 2010 after a 37-year absence.  The new Manukau Branch Line is due to open in Auckland in 2012.

The Castlecliff Industrial Line in Wanganui also reopened in 2011 to meet a need to transport dairy products to the Port of Taranaki for export.  In 2012 the Rotorua Branch Line will reopen after a 10 year hiatus.

The future of other railway lines in New Zealand is currently being assessed, including the North Auckland line and the Napier to Gisborne line.

When railway lines re-open, there is a need to raise public awareness about the increased safety risks due to the renewed movement of trains around level crossings.

Always remember

Double check there is space on the other side of the crossing for your vehicle.
