West Coast Zone catchment management plans

We have begun a project to develop catchment management plans for Whāingaroa, Aotea and Kāwhia harbours. Catchment management plans are a way for people to share what they want their natural environment to be like in the next 20 to 50+ years.

Enhancing our land, fresh water and coastal environs is a priority for Waikato Regional Council. These plans are intended to guide Waikato Regional Council, iwi, communities and other stakeholders in the implementation of catchment restoration activities.
