Today's meeting is to help the community better understand the disease, response activities, and to ask questions of Biodiversity New Zealand.
"M. bovis is not a disease that spreads on wind or water, it is a very slow moving disease that is spread through prolonged and repeated cow-to-cow contact or through drinking infected milk," an MPI spokeswoman said.
She said MPI's quarantine measures were very effective in containing the disease and mitigating its spread.
The infected property in Northland is in quarantine lockdown to reduce the likelihood of the disease spreading. All infected cattle on the farm will ultimately be culled, in agreement with the farmer.
MPI is informing all immediate neighbours so they can take the necessary precautions to stop their cattle coming into contact with animals who may be carrying the infection.
"As naming the property has no implication to the wider public, other than immediate neighbours, MPI will not be identifying any properties who are infected with M. bovis until the property owner has decided to go public. This balances the privacy concerns of individuals with the need for farmers to protect their own farms," the spokeswoman said.
