Tranz Metro (formerly Cityrail and before that Cityline) was a New Zealand public transport operator. Beginning as the New Zealand Railways Corporation's Cityline division as a result of restructuring in the 1980s, in its final form Tranz Metro was the operator of Metlink's suburban trains owned by the Greater Wellington Regional Council in the Wellington Region of New Zealand. Since 3 July 2016, Wellington's commuter rail services have been operated by Transdev Wellington. History Suburban passenger rail services in Auckland and Wellington were a part of the New Zealand Railways Department, while bus services were owned either by city corporations or Railways Road Services. With the restructuring of the department into the New Zealand Railways Corporation in 1982, the Auckland suburban rail operation was branded "Cityrail Auckland" from 1984 and later in the mid 1980s suburban bus and rail services were branded Cityline as part of the Corporation's Rail Passenger Group. Further restructuring of the rail network came in 1991, and the suburban rail operations were renamed "Cityrail" after they were transferred to New Zealand Rail Limited in 1991. That year the Auckland Regional Council bought the Auckland Cityrail fleet and contracted New Zealand Rail to run it, extending the contract until 1993 and again for 10 years until 2003. In 1993 New Zealand Rail Limited was privatised, renamed Tranz Rail in 1995, with Cityrail rebranded Tranz Metro. On 15 December 2000, as part of management changes at Tranz Rail, the company split Tranz Metro into wholly owned subsidiaries Tranz Metro Auckland Ltd and Tranz Metro Wellington Ltd, with the intention of selling them. Stagecoach New Zealand and Greater Wellington Regional Council (GWRC) announced their intention to bid for the Wellington company, but both were barred by the Commerce Commission from doing so. Tranz Rail did not bid for the Auckland contract when it expired in 2003. Connex (later Veolia and now Transdev) won the contract, and took over from 23 August 2004. Tranz Metro Wellington reverted to a business unit of Tranz Rail, with new contracts being signed with GWRC in 2006 for network access, rolling stock maintenance and service delivery. The contracts expired in 2016. In 2004 Toll Holdings bought a majority shareholding in Tranz Rail and renamed the company Toll NZ, and on 1 July 2008 it was bought (less the Tranz Link trucking and distribution arm) by the government and renamed KiwiRail.
