Farmer group Groundswell NZ has written to all regional, district, city and unitary councils in New Zealand, requesting a halt to mapping of natural areas on private land until concerns are resolved.
It was the first of a range of actions being launched as farmers mobilised against what they described as "unworkable regulations".
The Groundswell campaign, started last year by Otago-Southland farmers was now spreading nationwide.
Initially, the campaign's focus was on the National Policy Statement Freshwater Management, but it had been broadened to include the National Policy Statement Indigenous Biodiversity, climate change policies and the Crown Pastoral Land Reform Bill.
It was now calling on landowners to refuse access to public agencies undertaking surveys on private land. That included significant natural areas (SNA) and wetland surveys.
