The 2011 New Zealand general election took place on Saturday 26 November 2011 to determine the membership of the 50th New Zealand Parliament. One hundred and twenty-one MPs were elected to the New Zealand House of Representatives, 70 from single-member electorates, and 51 from party lists including one overhang seat. New Zealand since 1996 has used the Mixed Member Proportional (MMP) voting system, giving voters two votes: one for a political party and the other for their local electorate MP. A referendum on the voting system was held at the same time as the election, with voters voting by majority to keep the MMP system.
