Conduct an independent review of the jet boat activity each commercial jet boat operator in New Zealand is offering, to measure the type of activity and the manner in which it is conducted against the benchmark of identified risk. For any operations carrying more than the identified level of risk, either take the necessary action to reduce the risk level, or allow the operation to continue but require the operator to give passengers an appropriate warning of the high risk factor, before they commit to embarking on the trip. The content of any such warning and the method used to convey it should be approved by the MSA.
