In New Zealand, the introduced common brushtail possum is a vector for the spread of "M. bovis". The Biosecurity Act 1993, which established a national pest-management strategy, is the legislation behind control of the disease in New Zealand. The Animal Health Board operates a nationwide programme of cattle testing and possum control, with the goal of eradicating "M. bovis" from wild vector species across 2.5 million hectares – or one-quarter – of New Zealand's at-risk areas, by 2026 and, eventually, eradicating the disease entirely.
