Coalition government and satisfaction with democracy: An analysis of New Zealand's reaction to proportional representation

Following approval of a referendum in 1993, New Zealand replaced its first- past-the-post electoral system with proportional representation (PR). Altho ugh support for PR was initially high, less than a third expressed support for the new system a year and a half after its implementation. We examine t wo explanations for this decline. One theory assumes that dissatisfaction w ith the new system is the result of a growing alienation with politics, exa cerbated by an unpopular coalition government that voters neither expected nor desired. Another theory assumes that evaluations of the new system are mediated by a preference for coalition or single party government. Our resu lts indicate that a preference for single party government, guided primaril y by partisan self-interest, has the largest impact. Nevertheless, negative evaluations of the performance of the coalition government helped contribu te to a loss in support for PR suggesting that government performance can a ffect citizen's evaluation of political institutions, particularly when sys tems undergo radical change.
