Through an amendment in the Electoral Act in 1965, the number of electorates in the South Island was fixed at 25, an increase of one since the 1962 electoral redistribution. It was accepted that through the more rapidpopulation growth in the North Island, the number of its electorates would continue to increase, and to keep proportionality, three new electorates were allowed for in the 1967 electoral redistribution for the next election. In the North Island, five electorates were newly created and one electorate was reconstituted while three electorates were abolished. In the South Island, three electorates were newly created and one electorate was reconstituted while three electorates were abolished. The overall effect of the required changes was highly disruptive to existing electorates, with all but three electorates having their boundaries altered. These changes came into effect with the. Māngere is based around the South Auckland suburbs of Mangere, Mangere Bridge, Favona and Mangere East. It has existed as an electorate since 1969; its boundaries were extended ahead of the introduction of mixed-member proportional voting in 1996, swallowing up a section of the former Papatoetoe electorate. In the 2007 boundary redistribution, Papatoetoe and Middlemore were transferred to the electorate. The 2013/14 redistribution did not change the boundaries further.
History
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. Māngere was first represented by Colin Moyle of the Labour Party in 1969. Moyle represented the electorate until his resignation in 1977 over what became known as the 'Moyle Affair', and a subsequent by-election was won by a young barrister named David Lange, who would become Prime Minister after Labour's 1984 election victory. Lange retired in 1996 and the nomination was handed to Taito Phillip Field, at the time the MP for Otara. Field was returned with a high share of the vote in subsequent elections, but following his expulsion from the Labour caucus in 2007, his former party nominated former Manukau Citydeputy mayor William Sio in his place, who won the seat with a majority of over 7,000 votes in the 2008 election. In the and s, Sio's majority was circa 15,000 votes.
