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. It is held by Jo Goodhew of the National Party, who was previously MP of the Aoraki electorate. Rangitata is a relatively safe National seat, though not as safe relative to its surrounding neighbours Selwyn and Waitaki due to both Timaru and Temuka being Labour Party strongholds.
In the 1887 electoral redistribution, although the Representation Commission was required through the Representation Act 1887 to maintain existing electorates "as far as possible", rapid population growth in the North Island required the transfer of three seats from the South Island to the north. Ten new electorates were created, including Rangitata, and one former electorate was recreated.
The boundaries of the Rangitata electorate were last adjusted in the 2013/14 review, when an area around Rakaia was transferred to the Selwyn electorate.
The current electorate includes the following population centres (with approximate populations in brackets):
The Rangitata electorate was first established for the 1887 election. The election was contested by William Rolleston, who had represented Geraldine in the previously Parliament, Searby Buxton, and William Palmer. Buxton beat Rolleston, who had been in Parliament since 1868, by 588 to 507 votes, with Palmer receiving 14 votes. Buxton held the electorate until the end of the term in 1890, when the electorate was abolished again.
