Southland District was formed through the 1989 local government reforms. Four local authorities were amalgamated at that time: Wallace County, Winton Borough, Stewart Island and Southland County. John Casey, who was first elected onto Southland County Council in 1977, oversaw the amalgamation and was elected Southland District's first mayor in 1989.
Southland District covers the majority of the land area of Southland Region, although the region also covers Gore District, Invercargill City and adjacent territorial waters. It has a land area of 30,400.94 km2, excluding inland waters such as Lake Te Anau, Lake Manapouri, and Lake Hauroko.
The district council is made up of twelve elected members, from various ward areas, and like any other local authority is elected every three years.
