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.
