Auckland's public transport system, comprising buses, trains, and ferries, is coordinated by Auckland Transport (AT), with Britomart Station (officially Waitematā) serving as the main hub. Historically, the city had a highly utilized tram network, which helped shape its early 20th-century growth and peaked at over 120 million annual boardings during World War II. However, the dismantling of this extensive tram system in the 1950s, coupled with a focus on motorway development and minimal rail investment, led to a dramatic decline in ridership, making Auckland one of the world's lowest for public transport patronage by the 1990s.
Since 2000, significant efforts have revitalized the network, including the construction of Britomart Station, the Northern Busway, the upgrade and electrification of the rail network, and the introduction of the integrated AT HOP card. These improvements, alongside a major redesign of bus routes, have spurred sustained patronage growth, increasing total boardings from 51.3 million in 2005 to 90.9 million by 2017. Further major projects, such as the City Rail Link and Eastern Busway, are underway or planned to meet Auckland's rapid population growth and further enhance its public transport system.
