New Zealand has a unitary system of government in which the authority of the central government defines sub-national entities. Local government in New Zealand has only the powers conferred upon it by the New Zealand Parliament. Under the Local Government Act 2002, local authorities are responsible for enabling democratic local decision-making and promoting the social, economic, environmental, and cultural well-being of their communities, as well as more specific functions for which they have delegated authority.
As of 2020, seventy-eight local authorities cover all areas of New Zealand. Local authorities are positioned within a two-tier structure of territorial authorities (district and city councils) and superimposed regional councils. In addition, until their abolition in 2022, district health boards were locally-elected bodies with responsibilities for oversight of health and disability services within a specified area, although these boards were not generally considered to be local authorities in the conventional sense.
