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

Before an area can be classed as
TB-free, surveys are used to assess
if TB is still present in wildlife. While
possums are the main source of
infection from wildlife it can be
difficult and costly to detect TB in
possum populations. Pigs are good
indicators of TB in possums because
they scavenge widely, so are likely
to get TB from 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
