"From the mid-19th century large numbers of moa bones were discovered alongside human tools. This raised questions about whether the moa had been exterminated by Māori, or by pre-Māori people. If the latter, who were these people and what happened to them? One answer was offered by the geologist Julius von Haast. He concluded that those who had hunted the moa belonged to pre-history and were a Palaeolithic people. Percy Smith’s Great Fleet story neatly offered an explanation for what happened to them and when: New Zealand was first populated by a primitive, nomadic, moa-hunting people (the Palaeolithic Moriori), before being replaced by a superior, agricultural people (the Neolithic Māori). The idea of the Great Fleet was accepted by Māori and Pākehā. Even the Māori scholar Peter Buck (Te Rangi Hīroa), who claimed he had special insights into Māori history because of his ‘Polynesian corpuscles’, nevertheless argued that Polynesians were Aryans who might have originated in the Middle East and most likely did live somewhere in India. Throughout his life he was an ardent supporter of the Great Fleet theory. He also generally supported the story of discovery by the earlier Polynesian explorers Kupe, Toi and Whātonga, but did not accept that there were pre-Polynesian Moriori in New Zealand. Smith’s narrative became a legend. At least until the 1970s, it was a feature of Māori and Pākehā learning, and was enshrined in New Zealand’s wider culture."
"Back to Maori DNA. For the past fifty years debate has raged over where the Maori came from. Some say China (Taiwan), others Indonesia. Events have recently taken a startling turn. Adele White, for the ABC television programme Catalyst (broadcast on 27 March 2003), used mitochondrial (female line) DNA to trace Maori origins back as far as mainland Asia. But where in mainland Asia? The answer came from a surprising quarter - by looking at the gene for alcohol. Adele`s supervisor, Dr. Geoff Chambers, found a match between one of the variant genes for alcohol with people from Taiwan, so it seemed the original homeland of the Maori people was Taiwan. Or was it? When Dr. Chambers` team studied the Y (male) chromosome, they found a different story. While the females came from China, most of the men came from Melanesia."
These two passages stand on two very different horizons. The first passage indicates that the Maori came from eastern Polynesia and then came to New Zealand via the story of the great fleet. The First one will be believed by many Maoris because I guess there is no other way to map it out. For example, this story has been portrayed in museums and other Maori history websites which constantly emphasizes the story according to them is the truth. However the second one states that the Maori originated from Taiwan and Melanesia. The second article does provide lot of scientific data which sounds more convincing. Yet, it is really difficult to pin down one idea here as there is not enough evidence provided.
