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 (after Te Urewera) natural resource 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.
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 river's 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 Whanganui. It is one of the country's longest navigable rivers.
The river valley changed in the 1843 Wanganui earthquake.
In the 1970s a minor eruption from Mount Ruapehu spilled some of the contents from the Ruapehu Crater Lake (the same root cause of the Tangiwai disaster). This toxic water entered the Whanganui River and had the effect of killing much of the fish life downstream. In the aftermath of the poisoning, eels as large as 8.2 kilograms (18 lb) and trout as large as 2.3 kilograms (5.1 lb) were washed up dead along the banks of the river.

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 Taupo. Many places along the river are named in his honour.
The Whanganui River has always been an important communication route to the central North Island, both for Māori and for settlers. It is, however, also a difficult river, with many stretches of white water and over 200 rapids. Despite this, for many years it was the principal route to the interior.
Prior to the arrival of Europeans, the area around the Whanganui was one of the most densely inhabited in the land. Unsurprisingly, with the arrival of the colonial settlers, the area near the river's mouth became a major trading post.
Although it was already a significant route to the interior, the major development of the river as a trade route was by Alexander Hatrick, who started the first regular steam-boat service in 1892. The service eventually ran to Taumarunui where rail and coach services connected with points north. One of Hatrick's original boats, paddle-steamer PS Waimarie, has been restored and runs scheduled sailings in Whanganui. Another of the Hatrick boats, MV Wairua, has also been restored and can be seen on the river.
During the early 20th century, the Wanganui River, as it was then called, was one of the country's top tourist attractions, its rugged beauty and the Māori kāinga (villages) that dotted the banks attracting thousands of tourists a year.
With the completion of the North Island Main Trunk railway, the need for the steamboat route to the north greatly diminished, and the main economic activity of the river area became forestry. During the 1930s, attempts were made to open the river valley up as farmland, but they were not successful. One legacy of that time is the Bridge to Nowhere, built to provide access to settlements long since abandoned.
The settlement of Jerusalem is of particular note. Jerusalem was home to two famous New Zealanders, Mother Mary Joseph Aubert, whose Catholic mission is still located at Jerusalem, and New Zealand poet James K. Baxter, who established a commune at the settlement in 1970.
Taonga and Māori land claims
The river is of special and spiritual importance for Māori, who also refer to it as Te awa tupua—it was the home for a large proportion of Māori villages in pre-European times. As such, it is regarded as taonga, a special treasure. In recent times,[when?] efforts have been made to safeguard the river and give it the respect it deserves.
For the same reason, the river has been one of the most fiercely contested regions of the country in claims before the Waitangi Tribunal for the return of tribal lands. In fact the Whanganui River claim is heralded as the longest-running legal case in New Zealand history with petitions and court action in the 1930s, Waitangi Tribunal hearings in the 1990s and land occupations such as the ongoing Tieke Marae occupation since 1993 and the highly publicised Moutoa Gardens occupation in 1995, refer to Moutoa Island.
On 30 August 2012 agreement was reached that entitled the Whanganui River to a legal identity, a first in the world, and on 15 March 2017 the relevant settlement was passed into law by the New Zealand Parliament. Chris Finlayson, the Minister for Treaty of Waitangi Negotiations, said the river would have an identity "with all the corresponding rights, duties and liabilities of a legal person". He said some people would consider it strange, but it is "no stranger than family trusts, or companies, or incorporated societies." The bill finalised 140-year-old negotiations between Māori and the government. The river will be represented by two officials, one from Māori and the other from the government.
Some early maps show that European settlers called the river the Knowsley River. For many years after it was known in some records as the Wanganui River, however the river's name officially reverted to Whanganui in 1991, according with the wishes of local iwi.
Part of the reason was also to avoid confusion with the Wanganui River in the South Island. The city at the river's mouth was called Wanganui until December 2009, when the government decided that while either spelling was acceptable, Crown agencies would use the Whanganui spelling.
Flora and fauna
A wide variety of flora and fauna can be found in the Whanganui River.
Blue duck/Whio populations can be found at the junction of the Whanganui River and the Mangatepopo and Okupata streams. The Nankeen night heron established roosts along the Whanganui River in the 1990s and is breeding in New Zealand only in this location.
The Whanganui River provides the habitat for eighteen species of native fish as well as lamprey and black flounder. Native fish species present include Cran's bully, upland bully, climbing galaxias, pouched lamprey, shortjaw kokopu, torrentfish and New Zealand smelt.
Other aquatic species
Other aquatic species present in the river include Longfin and Short-finned eels and koura. New Zealand freshwater mussels are also present in the river, although these have been shown to be in decline.
The Whanganui river and its tributaries are also home to a variety of invertebrates such as mayflies, stoneflies and caddis flies.
The Whanganui River basin contains a variety of flora species, much of which can be characterised as a broadleaf and podocarp forest; understory species include crown fern (Blechnum discolor), and a variety of other ferns and shrubs.
In 1892 Alexander Hatrick was contracted by Thomas Cook & Son to carry tourists to Pipiriki on the paddle-steamer PS Waimarie, the journey was "The Rhine of Maoriland" tourist route into the interior of New Zealand. The river boat subsequently carried mail, passengers and cargo.
On 18 June 2010 the Adventurer 2 river boat embarked, attempting to make the 230-kilometre (140 mi) voyage to Taumarunui. The first voyage to Taumarunui in 82 years. The Adventurer 2 now offers this trip to tourist as an historic alternative to jet boating and canoeing the river. Though in low water flows it cannot make it all the way to Taumarunui.
River boat landings
The Whanganui River was the supply artery for the early communities along its banks. River boats used to ply the river, and also into the Ohura River and Ongarue Rivers unless these routes were log jammed after floods.
Between 1891 and 1958 the Alexander Hatrick Riverboat service operated on the Whanganui River. The paddle-steamer Wairere ordered from London and shipped in sections then assembled in Whanganui in late 1891.
It is said that Taumarunui was the highest reach of the Whanganui River that was navigable by river boat. The river flow was managed by the "Wanganui River Trust Board" which built containing walls to direct and deepen the rivers channels for river traffic. Even so, river boats sometimes found it necessary to winch themselves up the more difficult rapids.
|Landing name||Community serviced||Distance from mouth||Travel time up/down||Coordinates|
|Te Maire Landing||Te Maire|
|Wades Landing||Retaruke Valley|
|Mangapurua Landing||Mangapurua Valley|
|Lower Pipiriki landing||Pipiriki|
|Te Tuhi Landing||Ahu Ahu River Valley|
|Hipango Park Landing||?|
The flow of the river has been altered with the diversion of water from the headwaters into Lake Taupo. This may have been a contributing factor to the demise of the raft race and means river boats can no longer make the entire trip to Taumarunui during the drier months (see below).
