Kelston is a New Zealand parliamentary electorate that returns one member to the House of Representatives. It was first formed for the 2014 election and was won by Labour's Carmel Sepuloni, who has held the electorate since.

Kelston is located in an area in Auckland south-west of Waitematā Harbour covering part of Te Atatū South, the suburbs of Glen Eden, Sunnyvale, Glendene, Kelston, New Lynn, and Avondale, part of Mt Albert and the suburb of Waterview, with the name coming from one of its component suburbs.^[1]

Kelston was proposed in the 2013/14 electorate boundary review and confirmed by the Electoral Commission on 17 April 2014.^[2] The increase in population in the Auckland region as recorded in the 2013 census meant an extra electorate was required to keep all electorates within five percent of their quota. To accommodate an extra electorate the Electoral Commission abolished Waitakere and established two new electorates, namely Kelston and Upper Harbour.^[2]

The Kelston electorate took over parts of the Te Atatū, New Lynn, Mount Albert and Waitakere electorates. The first three electorates are all safe Labour electorates while Waitakere was marginal; National's Paula Bennett won the electorate by just nine votes in 2011 from Labour's Carmel Sepuloni. Subsequently, Kelston was regarded as a safe Labour electorate. Labour selected Sepuloni as its candidate for the 2014 general election,^[3] and she won the election with a majority of over 5,000 votes to National's Chris Penk.^[4]
