An approved hazardous substance or new organism may be reassessed if there are verifiable grounds showing that the associated risks and/or benefits need reviewing.
Criteria for grounds include:
- significant new information about risks
- availability of another substance with similar or improved benefits and reduced risks
- a significant change in the quantity being used, or the way it is used.
Anyone may apply for a reassessment, which is treated in the same way as an application for a new approval.
The Chief Executive of ERMA New Zealand may apply for a reassessment, in the public interest.
It is a two-step process. First, there is an application for approval of the grounds for a reassessment, then the application for the reassessment itself.
ERMA New Zealand recovers part of the cost of processing applications through its fees and charges.
