New Zealand is divided into 16 Regional Councils. These are further divided into Territorial Authorities. There are 67 territorial authorities: 13 city councils, 53 district councils, and the Chatham Islands Council. Six territorial authorities (Auckland Council, Nelson City Council, Gisborne, Tasman, and Marlborough District Councils and the Chatham Islands Council) also perform the functions of a regional council and thus are known as Unitary Authorities.
