Elizabeth Rata of the University of Auckland has written a very good paper on The Treaty and Neotribal Capitalism. You can download the paper below. Rata examines the political-economic context of the orthodox intepretation of the Treaty of Waitangi and says that this arose from postwar economic changes and thr rise of identity politics. She offers a very different interpretation of the Treaty. She says the Treaty now plays a 'crucial role in legitimising the material and political aspirations of the neotribal elite'.
