The issue of shark cage diving was first brought to my attention in 2014 while hearing submissions on the Health and Safety at Work Bill. PauaMAC5, which represents commercial pāua divers, made representations about shark cage diving and some of the practices that were used to entice sharks to the area for viewing—some of them, allegedly, reckless. There are allegations of measures being used, including tuna bait, heavy metal music, and decoys, which has been attributed to the anxiety and tension between shark cage diving operations and other users—pāua divers and swimmers in the vicinity—and the fear that these activities are changing the behaviour of sharks, making them even more aggressive toward people.
