Kaikōura (or Kaikoura before 2008) is a New Zealand parliamentary electorate, returning a single MP to the New Zealand House of Representatives. The current MP for Kaikōura is Stuart Smith of the National Party, who won the 2014 election.
The Kaikōura electorate covers the north-eastern South Island, from Cook Strait in the north to the Ashley River in the south. At over 21,000 km2 (8,100 sq mi), it is New Zealand's fourth-largest general electorate by area. Its main towns are Blenheim and Kaikoura; other towns include Picton, Havelock, Cheviot, Hanmer Springs, Culverden, Amberley and Ashley. The electorate boundaries were not changed in either the 2007 or 2013/14 boundary reviews.
Kaikōura is one of the original 60 electorates drawn ahead of the change to Mixed Member Proportional (MMP) voting in 1996. It was made up by merging all of the old Marlborough seat with a large portion of Rangiora. Like the two electorates it replaced, Kaikōura is a safe seat for the National Party, returning a National MP at every election since it was created.
