Kawau Island is an island in the Hauraki Gulf, close to the north-eastern coast of the North Island of New Zealand. At its closest point it lies 1.4 km (0.87 mi) off the coast of the North Auckland Peninsula, just south of Tawharanui Peninsula, and about 8 km (5.0 mi) by sea journey from Sandspit Wharf, and shelters Kawau Bay to the north-east of Warkworth. It is 40 km (25 mi) north of Auckland. Mansion House in the Kawau Island Historic Reserve is an important historic tourist attraction. Almost every property on the Island relies on direct access to the sea. There are only two short roads serving settlements at Schoolhouse Bay and South Cove, and most people have private wharves for access to their front door steps.
