Mycoplasma bovis has been confirmed to be in Wairarapa.
The Ministry for Primary Industries confirmed today that cattle on a farm near Masterton had tested positive for the disease.
The farm concerned is a sheep and beef farm and was located through the tracing of animal movements from other affected farms.
The property is under legal controls restricting the movement of animals and other risk goods off the farm.
As part of the government and sector group programme to eradicate the disease, all cattle on the farm will ultimately be culled, in agreement with the farmer concerned around timing.
This new property brings the total number of Infected properties nationwide to 36.
