About Whanganui
The Whanganui River is a major river in the North Island of New Zealand. It is the country's third-longest river, and has special status owing to its importance to the region's Māori people. In March 2017 it became the world's second natural resource (after Te Urewera) to be given its own legal identity, with the rights, duties and liabilities of a legal person. The Whanganui Treaty settlement brought the longest-running litigation in New Zealand history to an end.

Whanganui in Depth
Geography
With a length of 290 kilometres (180 mi), the Whanganui is the country's third-longest river. Much of the land to either side of the upper reaches is part of the Whanganui National Park, though the river itself is not part of the park.
The river rises on the northern slopes of Mount Tongariro, one of the three active volcanoes of the central plateau, close to Lake Rotoaira. It flows to the north-west before turning south-west at Taumarunui. From here it runs through the rough, bush-clad hill country of the King Country before turning south-east and flowing past the small settlements of Pipiriki and Jerusalem, before reaching the coast at the city of Whanganui. It is one of the country's longest navigable rivers.
History
Māori legend explains the formation of the river in the Mount Taranaki legend. When Mount Taranaki left the central plateau for the coast, the land was split open, and the river filled the rift.
Another Māori legend explains that after Māui caught the giant fish that was to become the North Island of New Zealand, known as Te Ika-a-Māui, he prayed to Ranginui who then sent two tear drops to land on Māui's fish. These two tear drops then became the rivers Whanganui and Waikato.
According to Māori tradition, the river was first explored by Tamatea, one of the leaders of the original migration to the new land, who travelled up the river and on to Lake Taupō. Many places along the river are named in his honour.
