Special protocols have been established for the major shows, enabling the cattle to be included at the Royal NZ Show at Hawke's Bay Showgrounds Tomoana in Hastings on October 17-19 and the Canterbury Show in Christchurch four weeks later.
Hawke's Bay cattle section committee member Max Tweedie said comprehensive research revealed genuine risk of disease transmission would be minimal.
"Although the risk is low, all possible measures will be taken to reduce the risk of disease transmission during the event," he said. "The Hawke's Bay A and P Society is extremely motivated to do all it can to protect all exhibitors and their stock."
Canterbury event director Geoff Bone, whose society spearheaded the show's collaboration with the MPI, said updated processes would allow an "added layer" of security without impacting unduly on the experience and workload of exhibitors.
Continual contact with MPI will enable adjustments to be made if necessary, and his show will work closely with Hawke's Bay to learn from the experiences with the show in Hastings.
Hawke's Bay society general manager Sally Jackson said breeders and industry experts had been consulted over the last six weeks and there was unanimous agreement, indicating breeders were still prepared to have stock at the show. This will then keep alive competition for the centrepiece silverware, the Meat and Wool Cup.
"Events this year have highlighted the need for shows to be highly proactive in protecting their livestock exhibitors from infectious disease threats," she said.
Last year, the show in Hastings attracted 305 entries across more than 20 cattle classes.
