Banks Peninsula is a New Zealand parliamentary electorate which initially existed from 1996 to 2008, and was later recreated in 2020 ahead of the 2020 election.

[1] It was held by National's David Carter for the initial term, and then by Labour's Ruth Dyson from 1999 to 2008.

The Banks Peninsula electorate, as defined in 2020, includes some of southern Christchurch, with suburbs such as Oaklands, Somerfield, Cashmere, Woolston, Halswell, Heathcote, and Sumner.

More than half of the electorates contested in 1996 were newly constituted, and most of the remainder had seen significant boundary changes.

Labour's Ruth Dyson retained Port Hills for all four elections with a greater lead than she had seen for Banks Peninsula.

[4] In the boundary review of 2019/2020, the Representation Commission decided to make large changes to the boundaries of Port Hills, taking area in Halswell and parts of Bromley out and adding Banks Peninsula in, to manage large changes in population in the Christchurch and Selwyn areas.
