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 New Zealand census had been cancelled due to the Great Depression, so the 1937 electoral redistribution had to take ten years of population growth into account.
Settlements that fell into the initial Otahuhu electorate were Howick, Papatoetoe, Māngere, Manurewa, and Brookby.
In the previous parliamentary term, Petrie had represented the Hauraki electorate, which then had covered the South Auckland suburbs.
[8] In the 1963 general election the seat was abolished and Bob Tizard stood in Pakuranga, so only represented Otahuhu from 16 March (after a by-election due to the death of James Deas) to 29 October 1963.
