Failings in NZ's stock tracking system

The National Animal Identification and Tracing (NAIT) scheme, which tracks animal movements around the country, has not worked as intended during the outbreak of the cattle disease Mycoplasma Boivs. The disease was first found in South Canterbury in July last year and has now spread from Southland to Hawke's Bay. To discuss the NAIT scheme and possible improvements to it, Kathryn is joined by Michelle Edge from OSPRI, the company which runs the scheme. Also Federated Farmers President, Katie Milne, and Dargaville farmer, Bob Steed.
