The TBfree programme aims to
control and eventually eradicate
bovine tuberculosis (TB) from
New Zealand by 2055.
We use possum control, along with
regular herd testing and movement
restrictions, to achieve this objective.
Information gathered from wild
animal surveys, recent and historic
findings of TB in wild animals, herd
testing results and the operational
history of the region is used when
planning operations.
The TBfree programme is delivered
through TB management areas
(TMAs). These areas were created
based on the likely or possible
presence of TB in wildlife, similar
habitat features, known disease
patterns, geography and control
history. Each TMA has a specific TB
control plan designed to eradicate
TB as effectively as possible.
A TMA is made up of one or more
