The use benefits of Mount Cook National Park are not priced by the market mechanism, whereas many of the inputs necessary to operate and maintain the Park are priced. Estimates of the economic benefits are relevant information when deciding upon the allocation of resources to, and within, a system of national parks. In 1984, the consumers' surplus for adult New Zealand visitors was about $2.2 million. An estimate of the net national benefits is given by the consumers' surplus obtained by New Zealand visitors, plus the net benefits associated with foreign visitors, less the cost of Park management and land. rental. The net benefit of Mount Cook National Park, as it was in 1984, is likely to be positive, indicating that the benefits associated with the current use pattern of resources exceeds their opportunity cost to the nation. However, this result cannot be used to establish the optimality of current expenditure and management. Approximately 170 000 adults visited Mount Cook National Park over 1984; 29% were from New Zealand, 25% were from Australia, 18% were from the United States, and 7% were from Japan. Visitors to the Park spend money in towns and villages in the Mackenzie Basin area. Average adult visitor expenditure in the Mackenzie Basin area is $58. These expenditures give rise to secondary economic benefits and create opportunities for regional development. Visitor expenditures in the Mackenzie Basin area are associated with $13.4 million of additional regional output, $6.8 mill ion of additional regional income, and 196 jobs. These effects derive their significance from regional objectives; they are not indicators of the national benefits associated with Mount Cook National Park.

First and foremost, we acknowledge the significant contribution of the Department of Lands and Survey. The Department funded the project. But of greater significance to us, as a research group, was the assistance given by Department staff well beyond the requirements of their respective positions. In particular, we thank Martin Heine, Ray Slater and Alan Wilson (Mount Cook National Park); Nicholas Rae and Ian Whitwell (Head Office), and David Alexander (Christchurch). All have been most supportive throughout the duration of the project. Of the many businesses that have assisted us, we would like to recognise the contribution of staff of Mount Cook Airlines, THC Glencoe, THC Hermitage, and Glentanner Station. These people assisted us with information on bus and plane schedules. They also facilitated the collection of questionnaires. Post Office staff at Mount Cook National Park also assisted with the collection of questionnaires. The Ministry of Works and Development provided road side equipment. Mr Williamson (New Zealand Forest Service, Geraldine) advised us on forestry employment in the region. Vaughan Brown, Air New Zealand, supplied us with the necessary data on international air fares. Twizel Development Incorporated were most helpful, providing information on Twizel. This project would not have been feasible without the accommodation provided by the New Zealand Alpine Club. We are especially grateful to Judy Norman for arranging our accommodation over 1984. Special thanks are due to those who assisted us with preparing, distributing and collecting the questionnaire. Carolyn Shaw provided the Japanese translation and prepared the signs. She also translated the returned Japanese questionnaires. The following people assisted by distributing and collecting the questionnaires under a wide range of climatic conditions: Jeanie Ackley, Bill Baker, Margaret Baker, Rodney Hide, Brooks Hull, Kok Jiuan Jiuan, Shirley Matson, Satya Pandaram, Reinhard Pauls, Shaista Shameem and Joy Talbot. Pat Devlin, Anton Meister, Doug Pearce, Ron Sandrey and David Simmonds read an earlier draft and made very useful comments. We are grateful for their suggestions and absolve them from any responsibility for the final product. Five people are directly responsible for the quality of this final report. Pat Prendergast designed the cover of the questionnaire and the cover of this report. Carolyn Brown and Peter Richardson were responsible for the graphic illustrations. Finally, we would like to thank Nan Thomson for typing an earlier draft and Brenda Carter for typing the final manuscript. Janet Gough Geoff Kerr Basil Sharp 1. Introduction Undeveloped land was a relatively abundant natural resource during the early settlement of New Zealand. Government policy and the market process served to facilitate the transformation of this natural resource into goods and services of higher value. Land was cleared for agriculture; minerals were mined; and trees were harvested. Outputs from these processes provided the raw materials necessary for economic growth, international trade, and improved standards of living. Initially, economists did not recognise the services associated with land in its natural state, commonly assuming the opportunity cost of undeveloped land to be at most, zero.
