The Tasman District Council wants to release two new wasp-killing insects to New Zealand.
It has applied on behalf of a wasp control action group to the Environmental Protection Authority, to release the wasp-nest beetle and a hoverfly.
The introduced insects would combat the invasive wasps that cost the country about $130 million a year in damage and control measures.
Wasps attack honeybees, butterflies, flies and spiders and can be harmful to people – sometimes seriously.
The council says biological control agents are a sustainable option.
Public feedback is being sought until late on Tuesday.
