This comes after an independent report they commissioned found in the past four years nearly 140,000 hectares of land has been earmarked for forestry.
It is predominantly sheep and beef farms that will be taken out of production.
Wairarapa-based BakerAg reviewed land use change data, analysed farm sales and looked at Overseas Investment Office Intentions.
It found significant increases in the amount of farmland sold into forestry, driven largely by an increase in the carbon price.
The report couldn't outline exactly how much of the pastoral land sold into forestry was intended for carbon farming, but it estimated about 26,000 hectares of the land went to carbon-only entities.
