Appropriate use, I imagine, is a function of the nature of the locality and the long-established use by people in the community. Entrepreneurial activity has a tendency to promote change, to over-ride the status quo, to be disruptive. Where the status quo is bad these changes may be for the better, but what happens when the status quo is good, and doesn’t either need or want change? The Regional Coastal Environment Plan for the Canterbury Region (2005) addresses these issues in Chapter 6: “Principal areas for commercial and recreational activities such as those involving port operation, marine farming, swing and pile moorings, boat launching and storage facilities are to be identified. The activities associated with such areas are to be protected from the adverse effects of other activities that could preclude the appropriate use of the areas or make their use inefficient.”
