It is important that we have robust scientific evidence for all the work in the Ministry and as a base for freshwater policy options. We have sought external expertise to help us explore and test our approach, and to provide specialist advice on science and policy work.
This page provides information about the Science and Technical Advisory Group, its members, details of their report to the Minister for the Environment, and meeting minutes and documents leading to the development of the report.
About the group
The Science and Technical Advisory Group oversees the scientific evidence for freshwater policy development. The establishment of this group draws on useful discussions between freshwater scientists about policy development and the science behind the National Policy Statement for Freshwater Management (Freshwater NPS).
This group provides and technical advice on the Essential Freshwater work programme and other Ministry for the Environment work. It has a role in ensuring the interpretation of the science for policy development is accurate. It also helps improve protocols to better manage the incorporation of science into the policy process.

Report to the Minister for the Environment
STAG members provided a report to the Minister for the Environment in September 2019. Their report highlights a strong focus on the health of the environment and the waterbody. The report recommends changes to the national freshwater management framework to strengthen the relationship between this national direction and ecosystem health and functioning.
The meeting minutes and documents leading to the development of the report are listed below.
