An application for registration was lodged with the Environmental Protection Authority (EPA) in July 2017. The EPA has asked for additional information to provide clarification of some issues. It is expected that the EPA will ask for public submissions in September, closing in October/November, with a registration decision likely early in 2018.
The following documents, which were presented at meetings in August 2017, provide additional information about EDN, its manufacturer Draslovka, and the extent of biosecurity risks faced by New Zealand's export log and timber industry.
