Farmers say the release of dung beetles on farms will save them millions of dollars yearly in pasture maintenance, and help them clean up their environmental performance.
The Environment Risk Management Authority has approved an application from Landcare Research to import and release up to 11 species of dung beetles for use on pasture.
Federated Farmers' biosecurity spokesman, John Hartnell, says the beetles rapidly break down dung, which reduces greenhouse gas emissions and effluent runoff.
He says they also improve soil health and boost pasture growth.
The beetles will be released in the Auckland and Southland regions later this year.
