Castor Bay

Castor Bay is a bay and suburb of the North Shore City in the North Island of New Zealand. Located between Milford and Campbells Bay it forms part of Auckland's East Coast Bays. To the east lies the islands of Rangitoto and Motutapu which are easily visible from land.

The bay itself is quite small, but well sheltered, with a small bark area and an extended coastline stretching out to the north. Nearby John F. Kennedy Park contains old WWII bunkers that were used to survey the Hauraki Gulf. The northern headland of Castor Bay is the site of an old Maori Pa, Rahopara, that is believed to have been last inhabited and then abandoned in the 18th century, prior to European colonisation. Very little is known about the people who lived there but the tribe's ancient earth excavations are still visible.

Sam Hunt, one of New Zealand's most well known poets was born in Castor Bay.

The local primary school is Campbells Bay Primary School located on Aberdeen Road, nearby the Pupuke Golf Course.
