Gulf Harbour is a development some 4 km from the end of the Whangaparaoa Peninsula, towards the northern end of Auckland, New Zealand. It has one of the country's largest marinas, one of the country's top golf courses, and is regarded as a retreat for Auckland's well-off. The site is also known as Hobbs Bay, and was sold in the early seventies by landowners, the Hobbs family, who still retain some of the coastal area including the Hobbs Bay beach.
