So what's the regime overseas? Well, generally, in areas like Australia, South Africa, Mexico, and California, shark cage diving is prohibited except in specific places. In Australia, for example, it's only allowed in the Neptune Islands Group in South Australia at a site more than 30 kilometres from the coast. In Mexico, it's only permitted within the Guadalupe Island Biosphere Reserve that's some 260 kilometres from the mainland coast, and it's restricted to a small area there. In California, it's only permitted at the Farallon Islands and they're 45 kilometres off the coast, and things like chum or baiting and decoys aren't permitted. There's no work that has yet been done in New Zealand to identify areas where shark cage diving could occur without conflict with other users and where it was safe for sharks. So I prefer the approach which has been adopted overseas of a general prohibition and legislation which protects both sharks and people, and the Department of Conservation is developing policy with the intention of introducing legislation to do this.
