Williams said the new rules would give local councils “much more say over what is planted - and where it’s planted.”
“We’ve seen in Gisborne and Hawke’s Bay the kind of damage that can be caused when forestry slash is mismanaged - it was totally devastating for our communities, and we’re still recovering,” Williams said in a statement.
There will now be a requirement to remove slash from erosion-prone land, and the environmental effects of permanent pine forests will need to be managed the same way as plantation forests.
Federated Farmers had been “pushing really hard for this for some time now”, Williams said.
“It’s great to finally see some action that will make a difference for our rural communities.”
He said farmers had been “incredibly frustrated” with the amount of productive farmland that was being lost to “blanket pine tree plantations”.
In the last five years alone, there had been more than 200,000 hectares of productive farmland converted to pine trees and carbon farming - and Williams said it would probably never be farmed on again.
“This has completely hollowed out some of our rural communities.

“As the pines have moved in, the people have moved out - and the life of these small towns has gone with them.
“Federated Farmers generally hold a view that landowners are entitled to make their own decisions about how to use their land, but in this case, rules and regulations have completely distorted the market.”
