AREAS
TMA Boundary
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.

FERRET

Before an area can be classed as
TB-free, surveys are used to assess if TB
is still present in wildlife. We’re running
