Ostend is a settlement on Waiheke Island, in New Zealand's Hauraki Gulf within the Auckland Region. Ostend is located in the west of the island, on and around a small peninsula which juts into Putiki Bay, one of two large indentations in the island's southwest coast. The southwest of the island contains much of Waiheke's population, with Ostend being located immediately to the east of the settlement of Surfdale, and to the southwest of Onetangi.
Ostend is connected to Surfdale by a causeway which crosses the western arm of Putiki Bay. The area is used by boatsmen who moor their boats on the beach, as it is easy to access from the mainland marina at Half Moon Bay. Ostend is home to the island's only supermarket (Countdown), a branch office of the Auckland council, the island's Baptist church, and a medical centre. It is known as the industrial area of the island.
