The Tamaki River or Tamaki Estuary is mostly an estuarial arm and harbour of the Hauraki Gulf, within the city of Auckland in New Zealand. It extends south for 15km from its mouth between the suburb of Saint Heliers and the long thin peninsula of Bucklands Beach, which reaches its end at Musick Point. The inlet extends past the suburbs of Glendowie, Wai o Taiki Bay, Point England, Glen Innes, Tamaki, Panmure, and Otahuhu to the west, and Bucklands Beach, Halfmoon Bay, Farm Cove, Sunnyhills and Pakuranga to the east.It has several smaller "tributary arms" which extend from it: the Pakuranga Creek and Otara Creek in the east, and the Otahuhu Creek and Panmure Basin in the west. The Otahuhu Creek forms the eastern shore of the narrowest point on the Auckland isthmus: here it is about 1.25 kilometres (0.75 mi) to the waters of the Manukau Harbour, an arm of the Tasman Sea.
