The Ministry for Primary Industries will start telling farmers directly if neighbouring properties are infected with M. bovis cattle disease or are at high risk.
"Some farmers have expressed frustration at not being formally told when a neighbour's farm is identified as an infected property," Biosecurity Minister Damien O'Connor said.
"MPI [Ministry of Primary Industries] will start directly informing neighbouring farms of infected properties or high-risk properties. This will mean farmers can take appropriate steps to improve their on-farm biosecurity and reduce the risk to their own stock.
"This is a measured step that balances the privacy concerns of individuals with the need for farmers to protect their own farms," O'Connor said in a statement.
MPI would also publish a list on its website of the National Animal Identification and Tracing (Nait) numbers of all affected animals, including all those associated with or traced from an infected property.
