New Zealand imports almost all of its phosphate, as local sources are negligible. Fertiliser works such as those at Ravensbourne in Otago process it into superphosphate. When the nearby Milburn phosphate deposits were quarried in the 1920s, it was local rather than imported phosphate that was railed to Ravensbourne – over a distance of some 50 kilometres.
