Manawatū District is a territorial authority district in the Manawatū-Whanganui local government region in the North Island of New Zealand, administered by Manawatū District Council. It includes most of the area between the Manawatū River in the south and the Rangitīkei River in the north, stretching from slightly south of the settlement of Himatangi in the south, to just south of Mangaweka in the north, and from the Rangitīkei River to the top of the Ruahine Range in the east. It does not include the Foxton area and the mouth of the Manawatū River, or Palmerston North City (which includes Ashhurst). Its main town is Feilding. The district has an area of 2,624 km². Name and geography Manawatū is said to have been named by Hau, a great Māori explorer. As he pursued his wife, who had left him for another lover, along the south west coast of the North Island, he came across and named river mouths, including Whanganui, Whangaehu and Rangitīkei according to events that befell him at the time. He then came across the mouth of the large, wide Manawatū River; in awe of the sight and in fear he might not be able to cross it, he said "Ka tū taku manawa" (My heart stands still). The name Manawatū (often the Manawatu) also refers to the whole area centred on the Manawatū Plains, the floodplain of the Manawatū River, with Palmerston North as its principal city. Like some other areas of New Zealand such as Wairarapa and the King Country, the Manawatū in this sense has never had precisely defined boundaries, its extents determined largely by custom and preference. Always included are Palmerston North and all of today's Manawatū District, and usually included is that part of Horowhenua District lying north of Levin. Parts of Rangitikei and/or Tararua districts might also be included. Demographics Manawatu District covers and had an estimated population of as of with a density of people per km2.
