The cattle disease Mycoplasma bovis has been found on another farm in the South Island.
More than four thousand cattle have been culled since the disease was first discovered in New Zealand in July.
Since then it's been detected on eight properties in Canterbury and Otago.
Today the Ministry of Primary Industries says one of two Waimate farms placed under restrictions last week has tested positive.
MPI's still waiting on results for the second property.
Mycoplasma bovis causes udder infections, abortions, pneumonia and arthritis.
