Consideration was also being given to the incoming national environmental standards - intensive winter grazing regulations which come into effect on November 1, Cummings said.
"We know that farmers, often supported by catchment groups and industry groups, have been working hard to improve winter grazing practices.
"It was obvious from the flyover the majority of farmers were making a targeted effort to develop protections around the at-risk areas on their properties."
Cummings emphasised no enforcement action would happen without further assessment and ground investigations of what was observed from the air.
"The majority of the flyover work is checking intensive winter grazing practices, but also includes wetlands, forestry and any large-scale land disturbance."
Farmers needing a little help with their intensive winter grazing were being asked if they wanted to be referred to representatives from Federated Farmers or their industry groups, Deer NZ, Beef + Lamb or DairyNZ.
