Temuka was a parliamentary electorate in the Canterbury region of New Zealand from 1911 to 1946. The electorate was represented by four Members of Parliament.

In the 1911 electoral redistribution, the North Island gained a further seat from the South Island due to faster population growth. In addition, there were substantial population movements within each island, and significant changes resulted from this. Only four electorates were unaltered, five electorates were abolished, one former electorate was re-established, and four electorates, including Temuka, were created for the first time.^[1]

Through the 1911 electoral redistribution, the Geraldine electorate was abolished, and its area split between the new Temuka electorate and an enlarged Ashburton electorate. Initially, the Temuka electorate included the settlements of Temuka, Pleasant Point, Fairlie, Lake Tekapo, Mount Cook, and Twizel.^[2]

In the 1918 electoral redistribution, the Temuka electorate moved north and gained the town of Geraldine.^[3] In the 1922 electoral redistribution, the Temuka electorate moved slightly south with losing or gaining significant settlements.^[4]

In the 1927 electoral redistribution, the Temuka electorate moved significantly to the north, and Fairlie, Lake Tekapo, Twizel, and Mount Cook were lost, and Mt Somers was gained.^[5] Boundary changes through the 1937 electoral redistribution were minimal, with some area near the town of Temuka gained from the Timaru electorate.^[6] In the 1946 electoral redistribution, the Temuka electorate was abolished, with most of its area going to the Ashburton electorate, and the balance, including the town of Temuka, going to the Waimate electorate.^[7]

The electorate was established for the 1911 election.^[8] The first representative was Thomas Buxton of the Liberal Party, who had previously represented Geraldine and who retired at the end of the term in 1914.^[9] Charles John Talbot won the 1914 election,^[10] but was defeated at the 1919 election by Thomas Burnett of the Reform Party. Burnett represented Temuka until his death in 1941.^[9]

Jack Acland succeeded Burnett in a 1942 by-election. The electorate was abolished in 1946,^[8] and Acland was defeated standing for the Timaru electorate.^[11]
