ERADICATING BOVINE TB FROM WAIPUNGA 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 All operation dates provided Napier and Taupo and is cut roughly year to year, depending on wild animals are provisional and subject to in half, north to south, by the Napier present, habitat, progress toward TB – Taupo highway.

PIG SURVEY 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 work needs to be done. CONSULTATION WAIPUNGA TARGETING OSPRI aims to ensure that communities, land occupiers and TB HISTORY POSSUMS land users are notified of planned operations well in advance and have There is a history of TB being found To eradicate bovine TB from possum the opportunity to submit feedback in the small number of herds present populations, possum numbers need about any possible risks or sensitive in this TMA and a large number of TB to be kept extremely low – around areas that need to be managed. infected pigs, deer and possums have one to two animals every ten hectares. also been found.

TESTING HERDS Cattle and deer herds are monitored for TB through a combination of herd testing and carcass inspection at slaughter. The frequency of testing depends on the herd’s location, management and TB history. To check the testing frequency for your property visit ospri.co.nz/dcamap MOVEMENT CONTROL Parts of the Waipunga TMA are within the Central North Island Movement Control Area. For herds in the Movement Control Area, TB testing is required for cattle and deer before they are moved to another herd or farm.
