Geology and Minerals
The Onehunga Ironworks was a colonial-era iron smelting and rolling operation at Onehunga, on the Manukau Harbour, (now a suburb of Auckland, New Zealand). It was at one time claimed to be the largest ironworks in the Southern Hemisphere. It is significant, both as the first large scale attempt to exploit New Zealand's iron-sand by direct reduction, and as a precursor of the modern steel industry of New Zealand. The ironworks was located adjacent to the original Onehunga railway station. It operated—but not continuously—from 1883 to around 1895. It was partially demolished around 1903 but its brick chimney and some of its other structures were still standing in the late 1960s.
