The 2011 New Zealand voting system referendum was a referendum on whether to keep the existing mixed member proportional (MMP) voting system, or to change to another voting system, for electing Members of Parliament to New Zealand's House of Representatives.^[1] It was held on 26 November 2011 in conjunction with the 2011 general election.^[2][3]

The referendum was indicative (non-binding), and asked two questions. The first question asked voters if they wished to keep the existing MMP voting system, or change to a different voting system. The second question asked which alternative voting system the voter would prefer if New Zealand were to change voting system: first past the post, preferential voting, single transferable vote, or supplementary member.^[3]

The official results were returned on 10 December 2011, with voters voting by majority to keep the MMP voting system. First-past-the-post received the plurality of the alternative system vote.
