Sustainability assessments have become important tools for decision makers. This research assesses the sustainability of different types of tourists in New Zealand by using the concept of yield and by developing yield indicators in the areas of financial, public sector and sustainable yield. The concept and indicators have been developed in cooperation with the New Zealand tourism sector and therefore provide a sector-driven approach to implement a sustainability assessment. The analysis shows that there are numerous 'trade-offs' between indicators when attempting to define the 'ideal visitor type'. Coach tourists, for example, are the largest spenders and generate the greatest Value Added in tourism on a per-day basis, but they contribute less to the financial sustainability of tourism when the costs of capital are accounted for. Coach tourists are highly concentrated in a few key destinations and at the same time produce substantial amounts of CO2 emissions due to their air travel component. In contrast, backpacker and camping tourists provide greater financial yield and are more dispersed, but they are also the greatest user of publicly provided tourist attractions and therefore come at a higher cost to government than other tourist types. Camping tourists are also contributing considerably to CO2 emissions. The yield analysis proposed in this paper could be a valuable tool for complex policy decision making and identifying strategies that lead to high-yield tourism.
