Māori landowners are mulling legal action in an effort to stop proposed changes to the emissions trading scheme, which would see plantation forests no longer eligible for carbon credits.
That's due to concerns significant tracts of land are being converted to pine, a fast-growing tree, to take advantage of soaring prices under the ETS.
But this comes at the expense of planting natives, which are more expensive and take longer to grow but are better for biodiversity.
The climate change minister James Shaw spoke to Māni Dunlop.
