# Ocean Grove, New Zealand

Ocean Grove, also known as Tomahawk, is a suburb in the southeast of the New Zealand city of Dunedin. A semi-rural residential suburb on the Pacific coast at the southwestern end of the Otago Peninsula, Ocean Grove is located 6.5 kilometres (4.0 mi) southeast of Dunedin city centre.
The suburb is isolated from much of the city by the bluff of Lawyers Head, which rises immediately to the west of the suburb and the Andersons Bay Cemetery, and as such has the feel of a separate community. The suburb lies close to the banks of the Tomahawk Lagoon, a twin-lobed lagoon noted for its bird life. The inner lobe is a wildlife reserve. Tomahawk Lagoon is separated from the sea at low tide by Tomahawk Beach, which runs east from the Lagoon's mouth for about 1 kilometre (0.62 mi). A smaller beach, Smaills Beach, lies further to the east, beyond which is the outcrop of Maori Head, 2 kilometres (1.2 mi) from the lagoon's mouth. A rocky reef and the small Bird island lie close to the headland.
The suburb was known as Tomahawk until the 1930s, The name "Tomahawk", documented in the Otago Witness from 1852, is unlikely to be a reference to the weapon. It is more likely an anglicized form of the Māori words toma haka, often interpreted as "dance by a gravesite". Toma means a place of bones, or shrine for bones; haka is here taken to mean the Māori dance of challenge, but may rather be the Southern Māori form of the word hanga, to build or create. The suburb became part of Dunedin City in 1968. The suburb has one main road, Tomahawk Road, which runs roughly parallel with the coast and links with the suburbs of Andersons Bay and Tainui in the west. In the east, it becomes the rural Centre Road, which climbs to the ridge at the centre of the Otago peninsula before joining with Highcliff Road, the ridge road which runs between Shiel Hill and Portobello.
Ocean Grove's most notable structures are the remains of two World War II gun emplacements. These stand close to the Jack Fox Lookout, which is at the top of Tomahawk Bluff, the promontory which separates Tomahawk Beach from Smaills Beach. A notable two-storey house, Glen Cairn, the original Smaill family homestead, is located at Smaills Beach. It is now used as the headquarters of the Tautuku Fishing Club. Between Tomahawk Beach and Tomahawk Road is Tomahawk Domain and recreation ground, which serves as a sports ground and is home to Grants Braes football club.
