Greater Wellington, also known as the Wellington Region (Māori: Te Upoko o te Ika), is a non-unitary region of New Zealand that occupies the southernmost part of the North Island. The region covers an area of , and has a population of The region takes its name from Wellington, New Zealand's capital city and the region's seat. The Wellington urban area, including the cities of Wellington, Porirua, Lower Hutt, and Upper Hutt, accounts for percent of the region's population; other major urban areas include the Kapiti conurbation (Waikanae, Paraparaumu, Raumati Beach, Raumati South, and Paekākāriki) and the town of Masterton. The region is administered by the Wellington Regional Council, which uses the promotional name Greater Wellington Regional Council. The council region covers the conurbation around the capital city, Wellington, and the cities of Lower Hutt, Porirua, and Upper Hutt, each of which has a rural hinterland; it extends up the west coast of the North Island, taking in the coastal settlements of the Kāpiti Coast District; east of the Remutaka Range it includes three largely rural districts containing most of Wairarapa, covering the towns of Masterton, Carterton, Greytown, Featherston and Martinborough. The Wellington Regional Council was first formed in 1980 from a merger of the Wellington Regional Planning Authority and the Wellington Regional Water Board. Following the creation of the Auckland Council 'super-city' in 2009, a similar merger for councils within the Wellington Region was investigated by the Local Government Commission in 2013. The proposal was scrapped in 2015 following negative public feedback. In common usage the terms Wellington region and Greater Wellington are not clearly defined, and areas on the periphery of the region are often excluded. In its more restrictive sense the region refers to the cluster of built-up areas west of the Tararua ranges. The much more sparsely populated area to the east has its own name, Wairarapa, and a centre in Masterton.
