New Zealand electorates

An electorate is a geographical constituency used for electing members to the New Zealand Parliament. In informal discussion, electorates are often called seats. The most formal description, electoral district, is used in legislation. The size of electorates is determined on a population basis such that all electorates have approximately the same population.

Before 1996, all members of Parliament were directly chosen for office by the voters of an electorate. In 2014 under the MMP electoral system, 71 of the usually 120 seats in Parliament were filled by electorate members, with the remainder being filled from party lists in order to achieve proportional representation (there were 69 electorates in 2005, and 70 electorates in the 2008 and 2011 elections). The 71 electorates are made up from 64 general and seven Māori electorates.

Originally, electorates were drawn up based on political and social links, with little consideration for differences in population. The New Zealand House of Representatives was originally modelled on the electoral procedures used for the British House of Commons, where there were both single-member electorates (electorates returning just one MP) and multi-member electorates (electorates returning more than one MP). Each electorate was allocated a different number of MPs (up to three) in order to balance population differences. All electorates used a plurality voting system. From 1881, a special country quota meant that rural seats were allowed to contain fewer people than urban seats, preserving the inequality and over-representing farmers. For the 1905 election the multi-member electorates were abolished. The quota system persisted until 1945.
