Expected direct costs of an oil spill in a UNESCO World Heritage area in New Zealand

Abstract

AbstractFiordland National Park is a UNESCO site located in the remote, southwest of New Zealand's South Island, which attracts hundreds of thousands of visitors every year. One of its leading attractions is Milford Sound. An oil spill in this area could not only impact the industries that operate in Milford Sound but also impact all of the park. To improve the knowledge base about this area in regard to oil spills and policies regarding ship visitation, this study aimed to estimate the costs of clean‐up, impacts to fisheries, tourism, recreation and the wildlife/environment under three oil spill scenarios in Milford Sound. Minimum costs are estimated at NZD 140–154 million. These results demonstrate the need for proper planning and response measures, and appropriate domestic and international policies to help minimise the potential damages that may occur in the event of an oil spill in a remote and pristine area of New Zealand.
