the office-seeking motivation plays an important role with those actors located in the centre of the party system. (3) As to the characteristics of the 'new' parties in the system, we interpret these parties as 'Schumpeterian' political entrepreneurs who instead of being genuine centre parties strategically place themselves in the centre in order to enhance their bargaining power.

In an earlier articlel we argued that electoral reform has affected New Zealand's party system less than is often assumed. Basically its format has changed to multi-party politics whereas its mechanics-the way competition is structured-stays bipolar and centripetal. The fundamental reason for this is that the potential for establishing a permanent and genuine centre party is small. We based this analysis on two main findings: (1) the policy space stays uni-dimensional, i.e. party competition is structured by a dominant left-right policy dimension; (2) since the office-seeking motive plays an important role for the main parties in coalition bargaining, coalition theories based on the size principle have a strong predictive quality. How does this argument work for the results of the 1999 general election?2 BIPOLAR COMPETITION IN A MULTI-PARTY SYSTEMCompared to 1996, the effective number of parties based on share of votes has decreased from 4.36 to 3.86. The respective numbers for the share of seats are 3.76 in 1996 and Dr Andr6 Kaiser is Assistant Professor in Political Science at the University of Mannheim. He is editor of Regieren in Westminster-Demokratien (Baden-Baden: Nomos, forthcoming) and has published widely on British politics and concepts in empirical democratic theory.
