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 South Westland Alps TMA lies adjacent to the main divide and extends south from Arthurs Pass to just beyond Whataroa. The TMA contains the high-risk catchments for the Waitaha, Poerua and Wanganui Rivers.

The habitat includes bush covered faces interspersed with glaciers.

History of TB and pest control in The South Westland Alps TMA

The South Westland Alps TMA has not undergone control under the TBfree programme.  

TB has been found in wild venison recovery deer and subsequently in possums surveyed in the valley floor below where the deer had been captured. Many TB positive deer were recovered in 2018 which may indicate that the prevalence of TB in the possum population is moderate to high.

Current state

There are no herds within the South Westland Alps TMA, but this TMA is a confirmed source area for TB infection in the Hari Hari area.

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 South Westland Alps 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.
