New Zealand First says it will introduce a "Canadian-style" law to ensure log exports don't destroy New Zealand's wood processing industry.
"We have a bill before Parliament to do just that," party leader and Northland MP Winston Peters said.
"Forestry is our No 3 export, but it is being vacuumed up by foreign-owned companies, with devastating results for the wood processing industry in provinces like Northland.
"When a Chinese company can employ 18 Chinese for the price of one New Zealand worker, how do New Zealand's wood processors compete for the raw log product in the first place? They can't, and politicians should understand that.
"Up here in the North a Chinese company is chopping down immature 20-year-old trees. That might suit their economy; it certainly doesn't suit ours. Meanwhile the National Government is an impotent bystander."
