| Parametric distributions applied to dichotomous choice contingent valuation data invoke assumptions about the distribution of willingness to pay that may contravene economic theory. This article develops and applies distributions that allow the shape of bid distributions to vary. Alternative distributions provide little, if any, improvement in statistical fit from commonly used distributions. While median willingness to pay is largely invariant to distribution, estimates of mean consumer surplus diverge widely. Sensitivity analysis to determine benefit measure response to distributional assumptions is essential to prevent erroneous policy advice from applied dichotomous choice research. |

| Efficient water management requires information on the magnitudes of all values associated with water volumes and quality, both in-situ and in extractive uses. This paper reviews and summarises New Zealand research into extra-market values placed on water. Studies have addressed issues as diverse as maintenance of ground water and instream flows, the value of recreational activities, and the quality of household water supplies. Results indicate that people place high values on avoiding further degradation of the natural environment, and in-situ values can have a significant role in water allocation efficiency despite high consumptive values of water. |

| In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture’s impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance... |

| Recreational anglers are known to seek different types of experiences in different settings. Such preference and behavioural diversity has important management implications. Research methods which assume only a limited degree of preference heterogeneity and impose rigid substitution patterns can impair understanding of individual’s unique decision process and lead to misguided management and policy recommendations. This paper reports results from an internet-based stated preference survey of recreational trout anglers in the North Canterbury Region of New Zealand. A mixed logit model, which simultaneously specifies random parameters plus error components, is used to capture the extent of random preference heterogeneity in systematic utility along with... |

| Beginning in 2000 Lincoln University has completed biennial surveys of people's perceptions of the state of the New Zealand environment. The surveys use the Pressure-State-Response framework for state of the environment reporting to assess resources such as air quality, native plants and animals, native forest and bush, soils, beaches and coastal waters, marine fisheries, marine reserves, freshwaters, national parks, wetlands, urban environments, and the natural environment compared to other developed nations. They also examine participation in environmentally friendly activities, the most important environmental issues facing New Zealanders and a range of other issues. Individual case studies are also undertaken: in 2000 natural hazards; in 2002 the... |
