New rules for New Zealand's 1.7 million hectares of plantation forestry have been announced.
Environment Minister Nick Smith says they're designed to better protect the environment and cut compliance costs.
"Forestry is New Zealand's third largest primary industry but its efficiency is hampered by the confusing mix of planning rules across New Zealand's 86 councils," he said.
The new rules are a national approach and include measures to control erosion and wilding pines.
"The strength of this national approach is that it will better protect the environment while also improving the productivity of the forestry sector by applying consistent environmental standards," Dr Smith said.
