Otahuhu is a suburb of Auckland. It is located 13 kilometres (8.1 mi) to the southeast of the city centre, on a narrow isthmus between an arm of the Manukau Harbour to the west and the Tamaki River estuary to the east. The isthmus is the narrowest connection between the North Auckland Peninsula and the rest of the North Island, being only some 1200 metres wide at its narrowest point, between the Otahuhu Creek and the Mangere Inlet. As the southernmost suburb of the former Auckland City it is considered part of South Auckland.
Despite its spelling locals typically do not pronounce the second “hu”, it is usually referred to as simply “Otahu” (although it would never be written this way).
