Download Whangarei Harbour sediment and E. coli study: catchment economic modelling

Northland Regional Council has identified that sediment and E. coli are key water
quality challenges in the Northland region. As a result, NRC has engaged in a joint venture with MPI to commission the Whangarei Harbour Sediment and E. coli study. This report looks at cost-effective ways to manage sediment and E. coli loads in the Whangarei Harbour catchment. These include both practice-based approaches (e.g. fencing streams) and outcome-based approaches (e.g. reducing sediment loads by 20%).
