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 as effectively as possible.
