Oruamo or Hellyers Creek is a stream and tidal estuary of Upper Waitematā Harbour in the Auckland Region of New Zealand's North Island. It flows through the western North Shore.

Greenhithe is a northwestern suburb of Auckland, New Zealand, located on the North Shore. Greenhithe was the location of Tauhinu, a fortified Te Kawerau ā Maki and Ngāti Whātua pā which overlooked the entrance to Oruamo or Hellyers Creek, that was settled until the 1820s. In the 1860s, the Forgham family established a community at Greenhithe, which by the 1880s had become a major fruit producer for Auckland. Boat repair and construction became major industries in Greenhithe in the 1960s.
