However both Nash and McAnulty said the Government will still enact policy to get the right trees planted in the right parts of rural New Zealand. The Government is delaying the work while it worked up a response to the Climate Change Commission's advice on how to meet the country's emissions reduction commitments.
The Government's response will have an impact on demand for trees to sequester carbon.
Nash said the task of changing land use rules for forestry was bigger than he first anticipated.
"You scratch the surface and actually we understand that there's a little bit more work to do than I had initially planned," Nash said.
"We felt it would be prudent to wrap the work we're doing in forestry into all the other work that's going on with regard to addressing climate change action."
Nash said he was talking to Climate Change Minister James Shaw about what changes "we need to make to actually give it the effect it should have".
The Government is still committed to the idea of "right tree, right place", however.
McAnulty said that in many cases the policy was already running. He said Land Information Minister Damien O'Connor had recently briefed a select committee that he had "no applications for blanket conversion through the Overseas Investment Office on classes 5 and below", meaning that, at least for foreign companies wanting to get into plantation forestry, the policy was already effectively working.
"I'm pleased because the policy in terms of ministerial discretion is applied anyway," McAnulty said.
"It's still going to happen but it's tied into broader work," he said.
The scale of the problem may have been overstated to begin with. The latest data shows that since 1989, 87 per cent of ETS-registered forests were planted on land use classes of 6 and above.
