In the Māori mythology of some tribes, Kupe (10th century) was involved in the Polynesian discovery of New Zealand.
There is contention concerning the status of Kupe. The contention turns on the authenticity of later versions of the legends, the so-called 'orthodox' versions closely associated with S. Percy Smith and Hoani Te Whatahoro Jury. Unlike the attested tribal traditions about Kupe recorded before Smith and Jury, the orthodox version is precise in terms of dates and in offering placenames in Polynesia where Kupe is supposed to have lived or departed from. The orthodox version also places Kupe hundreds of years before the arrival of the other founding canoes, whereas in the earlier traditions, Kupe is most definitely contemporary with those canoes (Simmons 1976). In addition, according to legends of the Whanganui and Taranaki regions Kupe was a contemporary of Turi of the Aotea canoe. In other traditions, Kupe arrived around the year 1400 on other canoes, including Tainui and Tākitimu (Simmons 1976:20–25).
In the "orthodox" version, Kupe was a great chief of Hawaiki who arrived in New Zealand in 925 AD. He left his cousin Hoturapa to drown during a fishing expedition and kidnapped his wife, Kuramarotini, with whom he fled in her great canoe Matawhourua. During their subsequent journeys, they overcame numerous monsters and sea demons, including the great octopus named as Te Wheke-a-Muturangi, and discovered New Zealand. Returning to Hawaiki, Kupe told of his adventures and convinced others to migrate with him (Craig 1989:127; see also External links below).
David Simmons said "A search for the sources of what I now call 'The Great New Zealand Myth' of Kupe, Toi and the Fleet, had surprising results. In this form they did not exist in the old manuscripts nor in the whaikorero of learned men. Bits and pieces there were. Kupe was and is known, in the traditions of the Hokianga, Waikato, East Coast and South Island: but the genealogies given did not tally with those given by S. Percy Smith. The stories given by Smith were a mixture of differing tribal tradition. In other words the whole tradition as given by Smith was pakeha, not Maori. Similarly, the story of Toi and Whatonga and the canoe race leading to settlement in New Zealand could not be authenticated except from the one man who gave it to Percy Smith. Learned men of the same tribe make no mention of this story and there are no waiata celebrating their deeds. Tribal origin canoes are well known to the tribes belonging to them: but none of them talk as Smith did of six large sea-going canoes setting out together from Raiatea. The Great New Zealand Myth was just that". (Simmons 1977).
