ERADICATING
BOVINE TB FROM
BAY OF PLENTY
JULY 2018 | VERSION 2.0
TB MANAGEMENT
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.
A TMA is made up of one or more

eating TB-infected possum carcasses.
They can’t maintain TB within their
own population, so if they are
infected, it means it’s from another
species. Pig survey results will help
us to tell if TB is still in the area and
whether further possum control
work needs to be done.
