Thousands of cows are to be culled on a huge feedlot near Ashburton, which is infected with M-bovis.
The Ministry for Primary Industries has also announced that stock will need to be tested or reduced on 14 nearby farms that are deemed at risk.
In May, the government announced that the Ashburton feedlot was the only infected property remaining, however since then, two more properties have tested positive.
The Five Star Beef feedlot in Ashburton, owned by ANZCO Foods, farms about 14-thousand cattle. Simon Andrew is the M-Bovis programme director at MPI.
