Introduction
This paper provides a summary of data related to the management of cadmium in New Zealand’s agriculture and food systems. This includes: cadmium concentrations reported in phosphate fertilisers used in New Zealand since 2003, with a comparison to agreed voluntary limits; soil cadmium concentrations from soil samples collected by the fertiliser industry, regional councils and other researchers between 2006 and 2015 from across a broad range of land uses and soil types; trends in soil cadmium accumulation from the long-term flood irrigation fertiliser trials at Winchmore Research Station in Canterbury, New Zealand; and cadmium concentrations in food from the 2009 New Zealand Total Diet Study, with a comparison to international standards.
