This paper reports on the sustainability practices of New Zealand businesses based on two national surveys and a series of focus groups and interviews. There was an average increase of 10% in the number of companies adopting environmental practices from 2003 to 2006. There was less of an increase for social practices, although still more commonly adopted by companies than environmental practices. Values and beliefs of management were the overwhelming driver for the adoption of sustainability practices with reputation and brand also significant drivers. Costs, management time, and knowledge/skills were the three most commonly reported barriers to adoption of sustainability initiatives. The implications of the study are that for New Zealand business, there is a strong link with the business case for sustainability. For policymakers interested in achieving sustainability goals, the results suggest that a ‘soft’ approach to business practices may be in order in New Zealand.
