Christchurch Transport Board

The Christchurch Transport Board was an autonomous special-purpose municipal authority responsible for the construction, acquisition, and ownership of local transport assets and the operation of public transport services in the Christchurch region of New Zealand's South Island. Constituted as the Christchurch Tramway Board in 1902, it operated trams and buses to Christchurch's outer suburbs and satellite towns for 84 years until being disestablished in the 1989 local government reforms.

The Board assumed control of the existing network of privately run tramways and converted these to electric operation whilst also extending the network. Economy measures resulted in several tram routes being converted to trolley bus and later diesel bus operation from the 1930s. The remaining tram routes were progressively closed in the decade following the end of World War II as the infrastructure required renewal or replacement. The last of the Board's trams were withdrawn in 1954, followed by its trolley buses in 1956. Its operations were fully converted to diesel buses in 1964 when the last of its older vehicles were replaced, including its petrol buses.

Subsequent to its demise, the Board's bus operation was transferred to a Local Authority Trading Enterprise (LATE) and was just one of several service providers in Christchurch following deregulation in mid-1991. The remnants of the Board survive today as the Christchurch City Council-owned Red Bus, the name by which it has been known since 1991.
