Rangitata is an electorate in the South Island of New Zealand. It first existed for two parliamentary terms in the late 19th century and was re-established for the 2008 general election. It largely replaced the Aoraki electorate, but included parts of the Rakaia electorate as well. The electorate includes both rural areas, and towns such as Timaru and Temuka, these two towns being Labour strongholds giving the electorate a different composition to its more conservative neighbours Selwyn and Waitaki.
