Otahuhu (New Zealand electorate)

Otahuhu is a former New Zealand parliamentary electorate in the southern suburbs of the city of Auckland, from 1938 to 1963, and then from 1972 to 1984.

The 1931 census had been cancelled due to the Great Depression, so the 1937 electoral redistribution had to take ten years of population growth into account. The increasing population imbalance between the North and South Islands had slowed, and only one electorate seat was transferred from south to north. Five electorates were abolished, one former electorate (Onehunga) was re-established, and four electorates were created for the first time, including Otahuhu.

For the purposes of the country quota, the 1936 census had determined that some 30% of the population lived in urban areas, and the balance in rural areas. Since the 1969 election, the number of electorates in the South Island was fixed at 25, with continued faster population growth in the North Island leading to an increase in the number of general electorates. There were 84 electorates for the 1969 election, and the 1972 electoral redistribution saw three additional general seats created for the North Island, bringing the total number of electorates to 87. Together with increased urbanisation in Christchurch and Nelson, the changes proved very disruptive to existing electorates. In the South Island, three electorates were abolished, and three electorates were newly created. In the North Island, five electorates were abolished, two electorates were recreated (including Otahuhu), and six electorates were newly created.

The Otahuhu electorate was located in the south of Auckland. Settlements that fell into the initial Otahuhu electorate were Howick, Papatoetoe, Mangere, Manurewa, and Brookby.
