The Hong Kong-based company making a bid to purchase the Crafar group of farms is outraged by statements made by the Government.
The receivers for the dairy farms formerly owned by the Crafar family, have agreed to sell them to Natural Dairy Holdings, if the Overseas Investment Office gives approval.
Agriculture Minister David Carter told a National Party conference at the weekend the sale is unlikely to go through.
Natural Dairy Holding vice-chairman, Graham Chin has called the statement an outrageous abuse of the Overseas Investment Office approval system.
A spokesperson for Mr Carter says he was expressing his personal opinion.
He has been instructed by the Prime Minister not to make further comment on the possible sale of the Crafar farms.
