Answer

I am advised that Biosecurity New Zealand is responsible for managing the national biosecurity system. The Department of Conservation is responsible for understanding and advising on the impacts on native species. The Department currently undertakes targeted management of pest wasps via the national Wasp Wipeout programme to address the effects on native species, including New Zealand Butterflies. Management is prioritised where there are significant impacts on biodiversity or visitor safety. The main techniques include poison bait station control or individual nest destruction. In addition to this, the Department is currently undertaking research to develop and improve wasp management tools.
