NZX Regulation, the supervisory arm of the stock market operator, has placed a trading halt on dairy futures and options after technical errors led to discrepancies in information detailing how much product Fonterra Cooperative Group plans to offer in next week's GlobalDairyTrade auction, a benchmark for the derivatives. Trading was halted at 11.07am today "pending a correction to the announcement regarding the Fonterra Offer Quantities for the GlobalDairyTrade auction released yesterday afternoon," NZX Regulation said in a statement.
