Hamilton West is a New Zealand parliamentary electorate. It has been held by Gaurav Sharma MP previously of the Labour Party since the 2020 general election. Sharma now sits as an independent and on 18 October 2022, he resigned from parliament, thus triggering a by-election in the electorate. Hamilton West is regarded as a bellwether seat. In 17 of the 18 general elections since the electorate's creation, the party that has won the plurality of seats nationally has won Hamilton West. The sole exception was in 1993, when Labour won the electorate but National won the plurality of the seats.
