ERADICATING BOVINE TB FROM EAST TAUPO 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 Vector Control Zones (VCZs) within which possum control or wildlife survey operations may be carried out from year to year, depending All operation dates provided are eastern edge of Lake Taupo and on wild animals present, habitat, provisional and subject to consultation. is predominantly exotic pine forest. progress toward TB eradication It extends south down the shores and available funding.

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 work needs to be done.
