I share some of the concerns of the Hon Simon Upton, the Parliamentary Commissioner for the Environment, which he raised in the Salmon Lecture to the Resource Management Law Association last year, that those broad words which Labour is proposing as the purpose don't specify that safeguarding the biophysical environment is paramount. As Mr Upton noted, the clause is directed to enhancing the quality of the environment as a whole, rather than just the natural environment. So supporting the wellbeing of people rather than of ecosystems becomes the overriding goal of the legislation. And potentially such a purpose statement leads us down that well-trodden path under the RMA to balancing competing outcomes, to trading off the environment and nature against human wellbeing when decision makers are forced to make an overall broad judgment which contains quite a strong element of subjectivity. So a focus on human wellbeing creates an enormous uncertainty that nature will in fact be safeguarded.
