Te Matuku Marine Reserve is a marine reserve at the far south-east corner of Waiheke Island in the Hauraki Gulf. It protects one of the island's largest and least disturbed estuaries, and an area outside Te Matuku Bay in the Waiheke Channel. The reserve was established in 2005 and covers 613 hectares. It is managed by the Department of Conservation.
It is reached by car, about 25 minutes from Kennedy Point along Orapiu Road, and by boat. There is no public transport on this part of the island. Otakawhe Bay, the eastern-most beach of the reserve, has parking and easy access for kayaks, but the tidal currents are strong. Dogs are not allowed in the reserve. Fishing and collecting are prohibited. Visitors should check a tide chart, and take care on the soft mud at the head of Te Matuku Bay at low tide. Nesting birds, including New Zealand dotterels and oystercatchers, should not be approached. Our pick on Waiheke for a quiet estuary and marine reserve day.
