New Zealand's electoral system has evolved significantly since its inception. The shift from First Past the Post to Mixed Member Proportional in 1996 aimed to create a more representative parliament and increase political diversity.
MMP gives voters two votes - one for their local representative and one for a party. This system has led to more diverse representation in Parliament, including increased numbers of Mฤori, women, and minority groups.
New Zealand's Electoral System Evolution
From Westminster to Mixed Member Proportional
- New Zealand's electoral system originated from the British Westminster system utilizing First Past the Post (FPP) voting from 1853 to 1996
- Royal Commission on the Electoral System in 1985-1986 recommended a change to Mixed Member Proportional (MMP) representation
- Two referendums held in 1992 and 1993 saw majority of voters supporting the change to MMP
- Electoral Act 1993 officially established MMP as New Zealand's new electoral system
- Came into effect for the 1996 general election
- Transition to MMP aimed to create a more representative parliament and increase diversity of political voices
MMP System Structure and Reviews
- Under MMP, voters have two votes
- One for local electorate representative
- One for a party
- Subsequent reviews and referendums conducted to assess and potentially refine MMP system
- 2011 referendum reaffirmed public support for MMP
- 5% threshold implemented for parties to enter Parliament without winning an electorate seat
- Influences party strategies and voter behavior
- Overhang seats can occur when a party wins more electorate seats than its party vote entitles it to
- Potentially affects total number of MPs in Parliament (can increase beyond the standard 120 seats)
Electoral System Impact on Parliament
Increased Diversity and Representation
- MMP system led to more diverse representation in Parliament
- Increased representation for Mฤori (from 5% under FPP to about 20% under MMP)
- Greater representation for women (from 21% in 1993 to 48% in 2020)
- Enhanced representation for minority groups (Pacific Islanders, Asians)
- More proportional allocation of seats better reflecting overall party vote percentages
- Example: In 2020 election, Labour received 50% of party votes and 53% of seats
- Growth and representation of smaller parties in Parliament
- Led to multi-party political landscape (Green Party, ACT, New Zealand First)
Government Formation and Coalitions
- Coalition governments have become the norm under MMP
- Rare for single party to win outright majority of seats (Labour in 2020 was an exception)
- Formation of governments often involves complex negotiations between parties
- Secure majority through coalitions or confidence and supply agreements
- Examples of coalition governments
- 1996-1998: National-New Zealand First coalition
- 2017-2020: Labour-New Zealand First coalition with Green Party support
