This report was prepared by Beca Infrastructure Ltd (Jim Cooke – Project Manager) in collaboration with the following key science agencies and Regional Councils:

1. Ian Jowett (National Institute of Water and Atmosphere, NIWA) and John Hayes (Cawthron Institute) wrote Section 2 (Rivers).
2. Clive Howard-Williams and Brian Sorrell (NIWA) wrote Section 3 (Lakes and Wetlands).
3. Paul White (Institute of Geological and Nuclear Sciences) and Tom Heller (Beca Infrastructure Ltd) wrote Section 4 (Groundwaters).
4. Russell Death (Massey University), Matt Hickey (Otago Regional Council) and Dave Kelly (Department of Conservation) peer-reviewed Section 2 (Rivers). Dave Kelly also peer-reviewed Section 3 (Lakes and Wetlands).
5. Alastair Smaill (Auckland Regional Council) and Ian McIndoe (Aqualinc Research Ltd) peer-reviewed Section 4 (Groundwaters).
6. Barry Biggs (NIWA) assisted with integration issues and contributed to Section 2 (Rivers).

All of the above (excepting Brian Sorrell and Dave Kelly) attended a workshop in December 2006, which was facilitated by Greg Pollock (Beca). All authors were involved in peer-reviewing other sections.

Christina Robb (Ministry for the Environment, MFE) focussed the workshop on MfE’s requirements and provided valuable feedback during the course of the project.
