Biophysical modeling conducted by NIWA estimated the change in the natural capital of freshwater bodies as a result of increased stock exclusion.There are no observable market prices that reveal what the New Zealand public are willing to pay for water quality improvements that flow from stock exclusion policy identified by NIWA. A non-market valuation methodology, choice experiments was therefore used. This involved an online survey of New Zealand residents in October 2015, using a research panel. NIWA’s work describes the flow of services from freshwater under a range of management scenarios, whereas the willingness to pay work quantifies respondents’ preferences over these services relative to each other and other goods and services in the economy. The survey process achieved 2,032 responses with good representation of key population demographics. The choice experiment shows that respondents place substantial value on water quality improvements of stock exclusion policy.58en© Crown Copyright - Ministry for Primary Industriesenvironmental economicsnon-market valuationwater qualitystock exclusion policyReportANZSRC::140205 Environment and Resource EconomicsANZSRC::140213 Public Economics- Public Choice2253-3923978-1-77665-497-0
