Waitematā Harbour

The Waitematā Harbour is the main access by sea to Auckland, New Zealand. The harbour forms the northern and eastern coasts of the Auckland isthmus and is crossed by the Auckland Harbour Bridge. It is matched on the southern side of the city by the shallower waters of the Manukau Harbour.

With an area of 70 square miles (180 km), it connects the city's main port and the Auckland waterfront to the Hauraki Gulf and the Pacific Ocean. It is sheltered from Pacific storms by Auckland's North Shore, Rangitoto Island, and Waiheke Island.
