Eradicating bovine TB in NZ

As part of our TBfree programme we deliver our pest control operations through a framework of TB management areas (TMAs). TMAs are areas with known TB infection in livestock and wildlife. Each TMA has a specific TB control plan designed to eradicate TB as effectively as possible.

The Pisa TMAThe Pisa TMA

The Pisa TMA covers 126,704ha and encompasses the Pisa and Criffel Mountains that extend from Queenstown in the south through to Wanaka and Mount Roy in the northeast.

The landscape is a mixture of high country tussock and scrub together with lowland improved farmland. It supports a mixture of intensive and extensive farming.

History of TB and pest control in the Pisa TMA

TB was established in wildlife throughout the Pisa TMA from the early 1990s. Ferrets and feral pigs are widely distributed and so infection was common. Over the past 20 years, domestic herds were frequently infected but possum control undertaken during this period succeeded in suppressing infected herd numbers.

We completed ground control to erradicate possums in:

  • the Crown Range, Locharburn and Mount Roy blocks in 2014/2015
  • the Luggate and Glendhu Buffer blocks during 2017/2018
  • the Cardrona and Locharburn blocks in 2018/2019 and 2019/2020, and
  • the Luggate block in 2020/2021.

We carried out ferret surveys in:

  • the Luggate block during the 2017/2018, and
  • the Cardrona, Locharburn and Luggate blocks in 2018/2019 and 2019/2020.

We completed aerial operations in 2017 and 2018.

Current state

There are currently no infected herd in the Pisa TMA.

Future pest control operations

We plan our pest control operations up to 3 years in advance. The current year runs from July 2021 to June 2022.

Dates and control methods for pest control operations in the Pisa TMA are provisional and subject to change. If you’re affected by any upcoming operations, our pest control contractors will contact you before work begins. They will:

  • talk you through the specifics of each operation
  • explain what you need to do before the operations start
  • get your consent for the work to be done.
