Tracking New Zealand's transition from the first-past-the-postelectoral system, as used in Britain, to the mixed-member-proportional system, as used in Germany, this analysis examines New Zealand's pivotal 2002 election through a campaign study, a postelection study, and a midelection panel. Based on surveys of more than 5,000 voters and information from candidates, the data included profiles the campaign, candidates, media, issues, leaders, electoral systems, and social and political context of this key election. Essays from New Zealanders and Americans analyze central issues including the outcome of the election for the National Party, Labour Party, New Zealand First Party, and the United Future Party and the political importance of indigenous Maori voters.
