Region is the formal term for the top tier of local government in New Zealand. There are twelve regions, each governed by an elected regional council. Five territorial authorities (the second tier of local government) also perform the functions of a regional council and thus are known as unitary authorities. Most region boundaries follow territorial authority boundaries but there are exceptions. The southern boundary of the Auckland Region, for example, cuts through the middle of the Franklin District.

Regional authorities are primarily responsible for environmental management, including water, contaminant discharge and coastal management, river and lake management including flood and drainage control, regional land management; regional transport (including public transport), biosecurity or pest management; while territorial authorities are responsible for: local-level land use management (urban and rural planning); network utility services such as water, sewerage, stormwater and solid waste management; local roads; libraries; parks and reserves; and community development. Property rates (land taxes) are used to fund both regional and territorial government activities. There is often a high degree of co-operation between regional and territorial councils as they have complementary roles.
