A leading demographer says we need to rethink what it means to be Maori after finding that almost a fifth of all Maori in the world now live outside New Zealand.
Dr Tahu Kukutai, a Stanford-educated research fellow at Waikato University, told a Population Association conference in Auckland yesterday that 151,000 of the 815,000 Maori people in the world now live overseas - 140,000 of them in Australia.
She has used census data from Australia, Britain, the United States and Canada to calculate the numbers of Maori in those countries at the beginning of the last decade, and has estimated population growth since then.
The figures are approximate because some countries do not record Maori ethnicity directly so she had to estimate them by matching birthplace data with ethnic categories such as "other race not Chinese".
But she found that there were now multi-generational Maori communities living away from New Zealand. A third of people with Maori ancestry in Australia were born there, and about 6000 are third-generation Australian Maori whose parents were also born there.
