Transport
Private cars are the dominant form of transport in Christchurch, with 62% of commuter journeys utilising a private car, as of 2020. Historically, decisions on land use and infrastructure investment in Christchurch have tended to favour car travel, resulting in high adoption of cars. As of 2022, Christchurch has almost 2,500 kilometres (1,600 mi) of roads. The city is served by State Highways 1, 73, 74, 74A, 75 and 76. Christchurch has three motorways consisting of the Christchurch Northern Motorway (includes the Western Belfast Bypass), Christchurch Southern Motorway and the Christchurch-Lyttelton Motorway.
Christchurch has an extensive bus network, with bus routes serving most areas of the city and satellite towns. The local bus service, marketed as Metro, is provided by Environment Canterbury. The topology of the network broadly follow a spoke–hub distribution paradigm, with major routes intersecting the city and crossing at the central Christchurch Bus Interchange. Less-frequent 'connector' and 'link' services provide journeys between suburbs not on the major routes. Additionally, a service called the Orbiter connects the suburban mall hubs by running in a ring around the outside of the central city. Before the 2011 earthquakes, in addition to normal bus services, Christchurch also had a zero-fare hybrid bus service, the Shuttle, in the inner city. The service was suspended following the earthquakes. As of 2023 public transport mode share in the Greater Christchurch area was 2.8%, with daily journeys still well-below pre-earthquake levels.
Historically, Christchurch has been known as New Zealand's cycling city, even earning the nickname "Cyclopolis" around the turn of the 20th century. Mark Twain described Christchurch in 1895 as a place "where half the people ride bicycles and the other half are kept busy dodging them". The central city has very flat terrain and the Christchurch City Council has established a network of cycling infrastructure in the form of both dedicated and shared paths, such as the major Northern Line Cycleway. Post-quake public consultation on rebuilding the city expressed a strong desire for a more sustainable transport system, particularly greater use of cycling; this was reflected in the council's 2012–42 strategic transport plan. The number of cycle paths across the city has continued to increase since the earthquakes, with the roll-out of the Major Cycle Route initiative intending to create 100 kilometres (62 mi) of cycle paths in the city. This has contributed to a 30% increase in bicycle journeys between 2016 and 2023, with over 3.6 million cyclists detected at counting stations in a 12-month period. Data from the 2023 census revealed Christchurch as a national leader in the adoption of cycling as commuter transport. Nearly 25% of all bicycle commuters in New Zealand live in Christchurch, with the highest levels of adoption in suburbs with robust cycle infrastructure.
Trams were running as public transport in Christchurch as early as 1880, with the system mostly electrified beginning in 1905. Routes mostly centred around Cathedral Square connecting out as far as Papanui, New Brighton and Sumner, but all had ceased operating by 1954. In 1995, the Christchurch tramway system was re-established as a tourist attraction. The tram follows a short loop around central city streets, with stops at Cathedral Square, the Arts Centre, Canterbury Museum, Victoria Square and Cathedral Junction, which is also the location of the depot. The tram tracks are owned by the Christchurch City Council, with the trams supplied, maintained and operated by the Tramways Historical Society. In 2022 the tram tracks were extended south down High Street at a cost of NZ$3,600,000, though due to an engineering issue they derailed a tram and had to be relaid.
There is a cable car system called the Christchurch Gondola which operates as a tourist attraction, providing transport from the Heathcote Valley to the top of Mount Cavendish in the city's south-east.
Rail services, both long-distance and commuter, used to focus on the former railway station on Moorhouse avenue. Commuter trains were progressively cancelled in the 1960s and 1970s. The last such service, between Christchurch and Rangiora, ceased in 1976. After the reduction in services, a new Christchurch railway station was established at Addington Junction. The Main North Line railway travels northwards via Kaikōura to Picton and is served by the Coastal Pacific scheduled passenger train while the Main South Line heads to Invercargill via Dunedin and was used by the Southerner until its cancellation in 2002.
The most famous train to depart Christchurch is the TranzAlpine, which travels along the Main South Line to Rolleston and then turns onto the Midland Line, passes through the Southern Alps via the Otira Tunnel, and terminates in Greymouth on the West Coast. This trip is often regarded as one of the ten great train journeys in the world for the remarkable scenery through which it passes. The TranzAlpine service is primarily a tourist service and carries no significant commuter traffic.
Christchurch Airport is located in Harewood, 12 kilometres (7.5 mi) to the north-west of the city centre. The airport is the second-busiest airport in New Zealand, with regular passenger services from Christchurch to sixteen New Zealand and seven international destinations. The airport serves as the major base for the New Zealand, South Korean, Italian and United States Antarctic programs.
