One of the questions I asked in preparing for my contribution tonight was: can sharks be harmed by shark cage diving? Obviously, the Minister has articulated it, but DOC did commission a report in 2015 by Barry Bruce, who works for the Commonwealth Scientific and Industrial Research Organisation in Tasmania, and it's titled A review of cage diving impacts on white shark behaviour and recommendations for research and the industry's management in New Zealand. So the Department of Conservation have been engaged in this issue for a long time, because they actually permitted it. What we have to acknowledge is that the Department of Conservation developed a code of practice in 2013. They started permitting in 2014. Business had been practising since 2008 unregulated. They reviewed the code, and therein became the issues. What's interesting in this report is that great white shark cage diving occurs in areas—and I quote—"where the species naturally aggregates with all current operations focused around … seal/sea lion colonies." That's why the great whites congregate in this particular part of New Zealand.
