Te Iwi Maori [PDF ebook] 

Te Iwi Maori presents an engrossing survey of the history of the Māori population from the earliest times to the present, concentrating particularly on the demographic impact of European colonisation. It also considers present and future population trends, many of which have major implications for social and resource policy. Among questions explored are the marked fertility decline of the 1970s, urbanisation, emigration (especially to Australia), and regional population patterns.
