Chatham Rock Phosphate aims to be the premier supplier of direct application phosphate to the New Zealand and global agricultural sector. We are passionate about the benefit of direct application fertiliser to sustainable farming and agricultural practices. Chatham Rock Phosphate is the custodian of New Zealand's only material resource of environmentally friendly pastoral phosphate fertiliser. Our key role is connecting the resource with those who need it. Using this phosphate will support sustainable farming practices, including healthier soils and reduced accumulation of the heavy metal cadmium, dramatically lowering runoff to waterways and shrinking fertiliser needs over time. The phosphate deposit was formed in nodules on the Chatham Rise millions of years ago, and discovered in 1952 by New Zealand scientists. Over the following four decades public and private sector experts identified the potential for decades of supply of rock phosphate to nourish New Zealand farms. The resource has an estimated worth of $5 to $7 billion, representing one of New Zealand's most valuable mineral assets and is of huge strategic significance because phosphate is essential to maintain New Zealand's high agricultural productivity.
