Hon DAVID PARKER (Minister for the Environment): I would say a small but important fraction. The new system moves from managing effects to trying to manage for outcomes. One of the problems environmentally under the RMA that there's a general consensus on is that the "avoid", "remedy", and/or "mitigate" language of the RMA in the end, in respect of impacts from land use on things like water, ended up being mainly "mitigate", and the effect of mitigated increases in intensity and land use cumulatively amounted to very significant degradations in water.
