Management of marine mammal watching in New Zealand, through the development of the Marine Mammals Protection Regulations 1992, has highlighted the value of quality information, either in the form of expert advice or specifically targeted research. The regulations have evolved through a long process of consultation, research and review. As further research is undertaken and more is learnt about the interactions of humans and marine mammals, further fine tuning of the regulations will undoubtedly occur.
The operating conditions outlined in the regulations have apparently been successful in protecting cetaceans from the short-term, day-to-day effects of marine mammal watching. Many questions remain unanswered, however, about the long-term effects of marine mammal watching. The assessment of possible longer-term, cumulative impacts remains a challenge for the future.
