Fonterra has brought in external consultants to review its operation, as it faces growing criticism from farmer shareholders. Chief executive Theo Spierings is ruling out splitting the company. But he says the dairy co operative needs hundreds more people selling milk and fewer in support roles. Mr Spierings spoke with Kathryn Ryan on Nine to Noon this morning, and promised farmers he would deliver change. Reporter Sally Wenley is at the first day of Mystery Creek Fieldays. Sally has been in the Fonterra tent, and reports on the reaction she's hearing from farmers.
