Fifty businesses, including Fonterra, Countdown and Auckland Airport are launching a new Biosecurity Business Pledge.
It will see them commit to tackling threats such as imported pests within their supply chain.
Dairy Companies Association NZ executive director Kimberley Crewther says businesses need to be more conscious when it comes to biosecurity.
She says maintaining freedom from pests and diseases requires everyone's responsibility, and the country's not there yet.
