Having spent a month in New Zealand earlier this year I read Michael King's book when I got back to the daily grind. The blurbs on the back of the Kiwi edition seem to indicate that it is the seminal one-volume history of New Zealand. Not having read any other history of NZ I can't say how seminal it is, but it does give a comprehensive, clear and comprehensible description of New Zealand's development as a state and as a nation (or nations?).
King's writing is straightforward and pleasant, foregoing the staid formalism of more academic works; although occasional offhandedness seems a little too breezy. That shouldn't take away from the breadth and depth of the work, however. King's angle seems to be that the central problem for, and function of, the state, particularly as the years roll on, is to reconcile the differing views, mores, cultures, norms and, most importantly, concepts of property, of Maori and white New Zealander (Pakeha). Whether or not this is too revisionist a view I don't know.
Other subjects are well-covered too, particularly the peculiarly strong devotion to Empire, the role of war in forging a national, or at least Pakeha, consciousness, and the repeatedly disastrous consequences for the natural environment of human colonisation, memorably described as "future eating".
There seemed to be a couple of lacunae, although these may well stem from the fact that the book is intended for a New Zealand readership which has at least the most basic understanding of New Zealand's history - i.e. I may well be barking up the wrong tree. For instance, as I understand it, the Muldoon era was marked by divisiveness caused in part by Muldoon's power of personality. There's no real sense of this in the book. Second, King mentions the role of rugby in developing a distinctively Kiwi form of "mateship". But I would have expected that rugby deserved a few more lines - did the 1987 World Cup have any lasting bearing on New Zealand? I've also heard that the 1995 defeat precipitated the fall of the Shipley government in the next general election. Then again, as a one-volume history, the editing needs to be very tight. Third, as the previous review suggests, I Googled Littlewood Treaty and it does seem like it might be worth mentioning, even if only to verify or debunk the arguments surrounding it - King addresses the story of the Chatham Island Moriori people in just this manner. Finally, and this probably wouldn't be necessary in the New Zealand edition, a glossary of Maori terms would have been very helpful, as the sheer range of terms relating to kinship, tradition, honour, respect, land, authority and rank can become a little confusing.
Overall, though, King's work is very enjoyable and gives the reader a sense of the deep affection he holds for his native land. It does seem that his tragic death in 2004 robbed New Zealand of a good storyteller and a great historian. If you're not a Kiwi you'll have to take one or two things on trust but at least you'll have something to argue about the next time you bump into one in a bar.
