release of the Office of the Prime Minister’s Chief Science Advisor’s report Methamphetamine contamination in residential properties: Exposures, risk levels and interpretation of standards.

Zealand will work with interested stakeholders at that point.
“Mr Castle has provided recommended improvements in his report, regarding the definition of consensus and processes

“Standards New Zealand has accepted the review’s recommendations and is currently addressing these. We are also
committed to making further improvements to the broader standards setting process,” says Ms Tremain.
