Manawatū-Whanganui (; spelled Manawatu-Wanganui prior to 2019) is a region in the lower half of the North Island of New Zealand, whose main population centres are the cities of Palmerston North and Whanganui. It is administered by the Manawatū-Whanganui Regional Council, which operates under the name Horizons Regional Council.
Name
In the Māori language, the name is a compound word that originates from an old Māori waiata (song). The waiata describes the search by an early ancestor, Haunui-a-Nanaia, for his wife, during which he named various waterways in the district, and says that his heart () settled or momentarily stopped () when he saw the Manawatu River.
Whanga nui is a phrase meaning "big bay" or "big harbour". The first name of the European settlement at Whanganui was Petre (pronounced Peter), after Lord Petre, an officer of the New Zealand Company, but the name was never popular and was officially changed to "Wanganui" in 1854. In the local dialect, Māori pronounce the wh in Whanganui as , a voiced labial–velar approximant combined with a glottal stop, but to non-locals the name sounds like "Wanganui" and is hard to reproduce.
In 1991 the New Zealand Geographic Board considered demands from some local Māori to change the name of the river to Whanganui. After widespread controversy for many years, in September 2019 the New Zealand Geographic Board announced that from 18 October 2019 the name of the Manawatu-Wanganui region, and the regional council, would incorporate both the letter "h" and a macron, becoming "Manawatū-Whanganui". This became the official spelling of the name on 18 October, although the Manawatū-Whanganui Regional Council would continue to use the trading name of Horizons Regional Council.

Government
The region covers all or part of ten territorial authority areas. Parts of five of these are covered by five other regions of New Zealand, the most of any region. In descending order of land area the territorial authority districts are Ruapehu, the major parts of Tararua District and Rangitikei, Manawatū, Whanganui, Horowhenua, and small parts of Stratford, Waitomo, and Taupō. The largest city is Palmerston North, with a population of 85,300 (June 2012 estimate). It is the only territorial authority in the region to be administered by a city council.
The governing body of the regional council consists of 12 councillors from 6 constituencies across the region, elected by the public; from the north: Ruapehu (1 councillor), Whanganui (2), Manawatū-Rangitikei (2), Palmerston North (4), Horowhenua (2), Tararua District (1). It sits in Palmerston North. It has the responsibility for managing natural and physical resources, providing flood protection and monitoring environmental problems and fresh air, clean water, productive land and natural eco-systems. It is also responsible for public transport.
Geography
The region is dominated and defined by two significant river catchments, the Whanganui and the Manawatu. The Whanganui River, in the northwest, is the longest navigable river in New Zealand. The river was extremely important to early Māori as it was the southern link in a chain of waterways that spanned almost two-thirds of the North Island. It was one of the chief areas of Māori settlement with its easily fortified cliffs and ample food supplies. Legends emphasise the importance of the river and it remains sacred to Whanganui iwi. Māori along the coast and lowland plains grew kumara and other crops. The Manawatū River runs across the centre of the region, from rolling hill country in the east to the fertile Manawatū Plains in the west. The main city of Palmerston North is located on these plains, and is an important service city for the southern North Island as a whole. This river is unusual, in that it passes from hill country to plains through a gorge cut into much higher country, an indication that the hills have risen since the river formed.
To the southeast, a further, more sparsely populated area of the Tararua District lies between the sources of the Manawatū River near Norsewood and the Pacific coast. This area, often historically connected with both the Hawke's Bay Region to the north and the Wairarapa to the south, was historically simply known as Bush, a name which still survives in some businesses and organisations, most notably the Wairarapa Bush Rugby Football Union.
