Book excerpt: This revised edition of a classic introduction to the New Zealand political, constitutional, and electoral system covers recent elections and the constitutional and legal changes that have attracted the attention of the international community. Using a pluralist theory of the state, it describes the history and practice of New Zealand government. Political parties and special-interest groups, the governmental hierarchy, and the public sector are discussed with information on how these different influences affect the political scene. The historical perspective provided offers a vision of the evolutionary nature of New Zealand politics and the interactions that drive changes.
