Then we look at the role of iwi in monitoring the river—that is important. It's important that we develop a better understanding of the natural environment and the effects of human activities on the natural environment. The Parliamentary Commissioner for the Environment has pointed out repeatedly that there are huge gaps in our understanding of the natural environment, and only by more comprehensive monitoring, recording the data, and observing discharges to the natural environment, how water take and how land use affects biodiversity and affects the natural resources, will we actually be able to come up with better management plans. So I think it's very important and worthwhile that Ngāti Maru have a role in environmental monitoring of the river.
