Many thanks to the members of the Pesticide Advisory Group, who oversaw the development of this document and assisted with comments and peer reviews.

Jo Cavanagh from Landcare Research provided a significant contribution to subsection 5.6 and Appendix 6 with regard to soil guideline values. Ben Keet has extensively reviewed and edited sections 5, 6 and 7 from the viewpoint of a contaminated land practitioner.

Last, but not least, we would like to thank the Waikato Pesticides Awareness Committee (WaiPAC) for its extensive ground research, particularly in the early stages of this guideline. WaiPAC was established in 1989 as a voluntary (non-funded) group, with representation from many community and industry stakeholders with an interest in the safe and efficient use of agrichemicals. Since then WaiPAC has been actively promoting best practice and responsible use of agrichemicals within the community.

Inclusion in the list of acknowledgements does not imply that all persons named are in full agreement with the entire content of this guideline.
