There's about a hundred sharks that visit Foveaux Strait every year between December and June. There's a stable resident population around the island. We've heard about the beginnings of shark cage diving back in 2008, and how the community was actually polarised from the very beginning, and particular concern from commercial pāua divers. Because of these concerns the Department of Conservation engaged with the community, they discussed the risks, they looked at the intensity of the operations, and they understood the need for rules. They made an attempt to make an evidence-based decision, and they did that by getting an international review about the risks conducted by Barry Bruce from the Australian Commonwealth Scientific and Industrial Research Organisation. What he concluded was that there was no evidence that shark cage diving increases the risk to water users. So the scientific evidence with an international review said that there was no greater risk with shark cage diving.
