We thank Laura Watts (Greater Wellington Regional Council) and Mark Heath (Victoria University) for the use of their data on benthic cyanobacteria in the Wellington region. We are indebted to Cathy Kilroy (National Institute of Water and Atmospheric Research) for her advice and assistance during the development of benthic cyanobacterial sections. Mike Thompson (Ministry for the Environment) is thanked for his guidance throughout this project.

The Australian National Health and Medical Research Council is thanked for permission to include modified sections of their recreational guidelines (NHMRC, 2008) in this document.
