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 Timaru Creek TMAThe Timaru Creek TMA

The Timaru Creek TMA covering 11,907ha is situated on the north eastern shore of Lake Hawea and is centred around the Timaru Creek catchment. It is the last line of defence between the Otago Vector Risk Area and the Vector Free Area.

It is a tight mountainous river valley with extensive habitat throughout much of its length.

History of TB and pest control in the Timaru Creek TMA

TB was well established in the Timaru Creek TMA from the late 1980s and TB still persists in ferrets and pigs on the south-eastern side. While there is little stock grazing available, the cattle herds on either side of Timaru Creek have been infected during the past 20 years.

We completed aerial possum control in Timaru Creek during 2017/2018 covering just under 7,000 ha. We ran a ground control operation over 1300 ha In conjunction with the aerial operation and repeated that ground control in 2018/19.

We also carried out other ground-based possum control in the Timaru Creek area during 2016/2017.

We undertook:

  • pig surveys in 2015/2016 and 2017/2018 in the Timaru Creek and Upper Timaru Creek areas, and
  • a ferret survey in the Timaru Creek area during 2015/2016.

Current state

There are currently no infected herds in the Timaru Creek 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 Western Southland 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.
