[[File:NZ Territorial Authorities South Island.png|thumb|Territorial authorities of the South Island]]

There are 23 territorial authorities within the South Island: 4 [[List of cities in New Zealand|city]] councils and 19 [[Districts of New Zealand|district]] councils. Three territorial authorities ([[Nelson, New Zealand|Nelson City Council]], and the [[Tasman (district), New Zealand|Tasman]] and [[Marlborough Region|Marlborough]] District Councils) also perform the functions of a regional council and thus are known as unitary authorities.
