Māngere is based around the South Auckland suburbs of Māngere, Māngere Bridge, Favona and Māngere East. It has existed as an electorate since 1969. Māngere, and all of South Auckland, forms the safest part of the Labour Party's core vote. Even during landslide elections in the National Party's favour, such as in 1975 and 1990, no Labour candidate for Māngere was seriously troubled. In the 2025 boundary review there were small changes on the eastern boundaries of Māngere.
