Onekaka is a small coastal community in Golden Bay, at the northwestern tip of the South Island, New Zealand with a population of around 250. The name Onekaka is Māori and translated as 'burning sands'. It is the former site of a large ironworks that operated from 1920 to the early 1930s, pipes and pig iron were produced until the operation became uneconomical. Dairy farming is a significant activity occupying a large proportion of the land area. An old dam associated with iron works has recently been converted to a small scale hydroelectric scheme.
