30-581: Tarawera Falls is a 65 m (213 ft) high waterfall on the Tarawera River in the Bay of Plenty region in New Zealand 's North Island . The Tarawera River flows out of Lake Tarawera and across a rhyolitic lava flow that erupted from Mt Tarawera about 14,000 years ago. The river disappears about 30 metres (98 feet) back from the clifftop into flooded caves in the lava and pours out halfway up
60-526: A creek that runs into the lake by the outlet), first broke on 1 November 1904, with a main flood surge on 3 November 1904 which was assessed at a peak flow of 700 m /s (25,000 cu ft/s). This flood resulted in the raising of the river bed ( aggradation ), and sedimentation problems to 50 km (31 mi) downstream of the lake. 37°54′S 176°47′E / 37.900°S 176.783°E / -37.900; 176.783 Iwi Iwi ( Māori pronunciation: [ˈiwi] ) are
90-465: A general geographic region, or merely gave a waka name. Initiatives like the Iwi Helpline are trying to make it easier for people to identify their iwi , and the proportion who "don't know" dropped relative to previous censuses. Some established pan-tribal organisations may exert influence across iwi divisions. The Rātana Church, for example, operates across iwi divisions, and
120-414: A generally recognised territory ( rohe ), but many of these overlap, sometimes completely. This has added a layer of complication to the long-running discussions and court cases about how to resolve historical Treaty claims. The length of coastline emerged as one factor in the final (2004) legislation to allocate fishing-rights in settlement of claims relating to commercial fisheries. Iwi can become

Ngāti Tūmatauenga ("Tribe of Tūmatauenga ", the god of war) is the official Māori-language name of the New Zealand Army , and Ngā Opango ("Black Tribe") is a Māori-language name for the All Blacks . In the southern dialect of Māori, Ngāti and Ngāi become Kāti and Kāi , terms found in such iwi as Kāti Māmoe and Kāi Tahu (also known as Ngai Tahu). Each iwi has
180-449: A particular hapu may have belonged to different iwi at different times, the tension caused by the social and economic power moving from the iwi down rather than from the hapu up, and the fact that many iwi do not recognise spouses and adoptees who do not have kinship links. In the 2006 census, 16 per cent of the 643,977 people who claimed Māori ancestry did not know their iwi . Another 11 per cent did not state their iwi , or stated only
210-438: A prospective vehicle for ideas and ideals of self-determination and/or tino rangatiratanga . Thus does Te Pāti Māori mention in the preamble of its constitution "the dreams and aspirations of tangata whenua to achieve self-determination for whānau , hapū and iwi within their own land". Some Tūhoe envisage self-determination in specifically iwi -oriented terms. Increasing urbanisation of Māori has led to
240-480: A situation where a significant percentage do not identify with any particular iwi . The following extract from a 2000 High Court of New Zealand judgment discussing the process of settling fishing rights illustrates some of the issues: ... 81 per cent of Maori now live in urban areas, at least one-third live outside their tribal influence, more than one-quarter do not know their iwi or for some reason do not choose to affiliate with it, at least 70 per cent live outside
270-522: A way further upstream. The falls were formed where the 14,009 ± 155 BP Pokohu lava flow from the Waiohau eruption of Mount Tarawera covered earlier tephra deposits. Lake Tarawera's river outlet is 3 km (1.9 mi) upstream from the falls and at times of normal flow the Tarawera River progressively drains into fissures, flowing subsurface, until it emerges about mid cliff from caves in
300-544: Is where the Tapahoro lava flow, created by the 5526 ± 145 BP Whakatane eruption, runs into a 14,009 ± 155 BP Pokohu lava flow. The Tarawera River flows across this in a 10 m (33 ft) wide channel. The 1314 eruption blocked the outlet with a temporary dam up to 32 m (105 ft) above present outlet levels, which was subsequently eroded with a great flood that created a 350 m (1,150 ft) wide, and almost 40 m (130 ft) deep valley spillway at
330-728: The Māori King Movement , though principally congregated around Waikato / Tainui , aims to transcend some iwi functions in a wider grouping. Many iwi operate or are affiliated with media organisations. Most of these belong to Te Whakaruruhau o Nga Reo Irirangi Māori (the National Māori Radio Network), a group of radio stations which receive contestable Government funding from Te Māngai Pāho (the Māori Broadcast Funding Agency) to operate on behalf of iwi and hapū . Under their funding agreement,

#1732798812098360-496: The original migration voyages ). These super-groupings are generally symbolic rather than logistical. In pre-European times, most Māori were allied to relatively small groups in the form of hapū ( ' sub-tribes ' ) and whānau ( ' family ' ). Each iwi contains a number of hapū ; among the hapū of the Ngāti Whātua iwi, for example, are Te Uri-o-Hau , Te Roroa , Te Taoū , and Ngāti Whātua-o-Ōrākei . Māori use
390-481: The Pokohu lava flow. The major contributor to today's amphitheatre, was likely to be the large flood that followed the lake outlet damming by events associated with the 5526 ± 145 BP Whakatane eruption. It is postulated that plunge-pool undercutting rather than kolking created the amphitheatre. Boulders down stream of the falls are up to 20 m (66 ft) in diameter reflecting the much larger size of this flood than
420-452: The appeal was rejected. The Tarawera River drains the north-eastern aspect of the Taupō Rift with its river mouth west of Matata . The river commences at the north-east arm of Lake Tarawera with a mean outflow of 7 m /s (250 cu ft/s), from effectively a watershed of the Ōkataina Caldera , with its risk of volcanic activity disrupting river flow. At this normal or less flow
450-565: The bones" — literally to the burial-areas of the ancestors . Māori author Keri Hulme 's novel The Bone People (1985) has a title linked directly to the dual meaning of bone and "tribal people". Many iwi names begin with Ngāti or with Ngāi (from ngā āti and ngā ai respectively, both meaning roughly ' the offspring of ' ). Ngāti has become a productive morpheme in New Zealand English to refer to groups of people: examples are Ngāti Pākehā ( Pākehā as
480-612: The cliff on the far side of the flow. After rain, part of the flow passes over the top of the cliff as a 65 m (213 ft) tall companion fall. Access is from the town of Kawerau and is a drive of about 45 minutes over unsealed roads, followed by a walk of about 20 minutes. A forestry access permit is required, available from the Information Centre in Kawerau. The Te Arawa and Ngāti Awa tribes have traditional associations with this site. Ngāti Rangitihi , one of
510-403: The eight Te Arawa tribal groups, are the current guardians of the area and consider the site of the waterfall a sacred place. The vegetation in the area has only developed since the 1886 Tarawera eruption and contains an unusual range of hybrids between pohutukawa and rata . Migrating eels swim as far up as the waterfall and can sometimes be seen on the western side of the falls searching for
540-404: The falls and up to 13 m (43 ft) to 8 km (5.0 mi) below the falls. The lake outlet was blocked again after the 1886 eruption of Mount Tarawera , and the lake level increased to a maximum of 12.8 m (42 ft) above its present level. This volcanic debris dam (the debris that blocked the outlet were not just from the eruption directly but included those washed down from
570-506: The growing New Zealand Māori population tried to keep a connection to their culture, family history, spirituality, community, language and iwi . The Victoria University of Wellington Te Reo Māori Society campaigned for Māori radio, helping to set up Te Reo o Poneke, the first Māori-owned radio operation, using airtime on Wellington student-radio station Radio Active in 1983. Twenty-one iwi radio stations were set up between 1989 and 1994, receiving Government funding in accordance with
600-767: The largest social units in New Zealand Māori society . In Māori , iwi roughly means ' people ' or ' nation ' , and is often translated as " tribe ", or "a confederation of tribes". The word is both singular and plural in the Māori language, and is typically pluralised as such in English. Iwi groups trace their ancestry to the original Polynesian migrants who, according to tradition, arrived from Hawaiki . Some iwi cluster into larger groupings that are based on whakapapa (genealogical tradition) and known as waka (literally ' canoes ' , with reference to

The Tarawera Falls on the river are considered to be quite spectacular. The Tasman Pulp and Paper Mill , now owned by Norske Skog , has been discharging waste into the river since 1955. Local residents have erected signposts labelling
690-410: The river as the "Black Drain" since the 1990s. The dark colour is due to the presence of pollution from farms, sewage and stormwater but it is predominantly from pulp and paper mill effluent. As of 1997, pulp and paper mills were discharging over 160 million litres of industrial waste into the river per day. By 2006, the oxygen levels in the river had reached a level where fish could survive, however
720-493: The river disappears underground into caves in the rhyolite lava flow just before the Tarawera Falls. It usually emerges about halfway up the full falls drop, but can with recent rain fully occupy the drop. There have been two known major floods following the breakdown of temporary volcanic material dams at the lake outlet. The first, and larger, followed the 1314 ± 12 CE Kaharoa eruption. The present river start
750-589: The start of the river. It seems the river during this flood overflowed to the east draining for a time through the Awiti Ravine, and back into the Tarawera River flood plain by the present Waiaute Stream that drains the eastern slopes of Mount Tarawera. However it also evacuated 3 km (1.9 mi) downstream from the lake at the terminus of the Pokohu lava flow the amphitheatre of the Tarawera Falls. The flood deposited large boulders up to 20 m (66 ft) in diameter for 1 km (0.62 mi) below
780-483: The stations must produce programmes in the local Māori language and actively promote local Māori culture. A two-year Massey University survey of 30,000 people published in 2003 indicated 50 per cent of Māori in National Māori Radio Network broadcast areas listened to an iwi station. An Auckland University of Technology study in 2009 suggested the audience of iwi radio stations would increase as
810-408: The traditional tribal territory and these will have difficulties, which in many cases will be severe, in both relating to their tribal heritage and in accessing benefits from the settlement. It is also said that many Maori reject tribal affiliation because of a working-class unemployed attitude, defiance and frustration. Related but less important factors, are that a hapu may belong to more than one iwi,
840-591: The tribe has collective assets under management of $ 1.85 billion. Iwi affairs can have a real impact on New Zealand politics and society. A 2004 attempt by some iwi to test in court their ownership of the seabed and foreshore areas polarised public opinion (see New Zealand foreshore and seabed controversy ). In Māori and in many other Polynesian languages , iwi literally means ' bone ' derived from Proto-Oceanic * suRi ₁ meaning ' thorn, splinter, fish bone ' . Māori may refer to returning home after travelling or living elsewhere as "going back to
870-621: The water colour was still dark. Since 1998 the colour and light penetration ( euphotic depth ) have improved in the lower section of the river due to less pollution from the Tasman Mill. In 2009, the mill gained permission to continue polluting the river for the next 25 years. In 2010, local iwi took a case to the High Court to shorten the 25 year water discharge permits issued under the Resource Management Act but
900-546: The word rohe to describe the territory or boundaries of iwi. In modern-day New Zealand , iwi can exercise significant political power in the management of land and of other assets. For example, the 1997 Treaty of Waitangi settlement between the New Zealand Government and Ngāi Tahu , compensated that iwi for various losses of the rights guaranteed under the Treaty of Waitangi of 1840.
