Representing diversity in mixed electoral systems. The case of New Zealand.

This article examines the representation of ethnic groups in mixed electoral systems. Analysing data from all Members of Parliament (MPs) in New Zealand’s Parliament since the introduction of a Mixed Member Proportional electoral system in 1996, we show that, despite increases over time, some ethnic minorities (and especially the Asian population) remain underrepresented, although to varying degrees across political parties. Ethnic minority MPs are also significantly more likely than majority MPs to be elected from a party list, although differences exist among ethnic groups. Finally, women are better represented among ethnic minority MPs than among MPs from the ethnic majority, but they tend, amongst most ethnic groups, to be more likely than men to be list MPs.
