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

TARGETING
POSSUMS
To eradicate bovine TB from possum
populations, possum numbers
need to be kept extremely low
– around one to two animals every
ten hectares.
Previous possum control and
livestock disease management has
dramatically reduced the number
of infected herds in the Wellington
region. However monitoring has
shown that further control work
is needed in the Central Wairarapa
area to reduce the possum
population, to minimise the risk
of the disease spreading through
wild animal populations and into
farmed cattle and deer herds and
to ensure further good progress
towards disease eradication.
CONSULTATION
OSPRI aims to ensure that
communities, land occupiers and
land users are notified of planned
operations well in advance and
have the opportunity to submit
