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.
Kelston is located in an area in Auckland south-west of Waitematā Harbour covering part of Te Atatu 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.
Kelston was proposed in the 2013/14 electorate boundary review and confirmed by the Electoral Commission on 17 April 2014. 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.
