The AHB’s primary role is to manage the implementation of the National Pest Management Strategy for Bovine TB, with the aim of eradicating the disease from New Zealand.
Key functions include:
Vector control (wild animal control)
The major cause of TB in cattle and deer herds in New Zealand is contact with wild vectors (carriers) of the disease. Vector control is aimed mainly at possums and ferrets. The AHB surveys wildlife populations and classifies land areas according to the presence or absence of TB within those populations. Information from the surveys helps determine the best boundaries for vector control operations or if vector control can stop, be relaxed or intensified. Control work is carried out by contractors using either aerial or ground methods depending on factors like possum numbers, land use and accessibility.
Disease and movement control
Disease control includes all measures to detect and eradicate TB within cattle and deer herds, and to prevent transmission of the disease through the movement of infected livestock. Disease control work involves:
- Herd registration and classification
- Ongoing testing of cattle and deer in New Zealand and the slaughter of any animals suspected of having TB
- Control of movement from infected herds and high risk areas
- Monitoring and enforcing compliance.
Research
The board has an extensive research programme which guides its work. It initiates studies into:
- New methods of diagnosing TB
- The impact and effectiveness of toxins currently being used for vector control
- New control tools, methods of application and monitoring
- Investigation into biological control options for vector control
- Knowledge sharing through conferences, meetings and scientific publications.
Communications
The AHB carries out national and local communications to support the implementation of its vector and disease control programmes.
Operational activities
Most of the AHB’s operational activities are contracted out to other organisations.
