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 East Otago TMAThe East Otago TMA

The East Otago TMA covers 147,000 ha extending from Waitati to Palmerston and then inland towards Central Otago.

It is mostly coastal habitat but is wetter and has more vegetative cover than the dry country further inland. There are substantial areas of native and exotic forestry, broken rough scrubland and improved farmland.

History of TB and pest control in East Otago TMA

The East Otago TMA has a long history with TB infection in both wildlife and cattle herds. Infection has been present since the 1980s and still persists today. Ferrets and feral pigs are widely distributed, and infection has been common among wildlife. Infection was also frequent in cattle herds. Infected wildlife was last found in 2012.

We carried out ground control of possums in:

  • the Shag Valley in 2015/2016
  • Pigroot, Silver Peaks, Sister Peaks, Stoneburn, Waikouaiti Ext, Waikouaiti North, and Waikouaiti South control areas all had ground control operations in 2016/2017
  • the Dunback and Silver Peaks areas in 2017/2018
  • Dunback, Pigroot, Shag Valley, Sister Peaks, Stoneburn, Waikouaiti Extension, Waikouaiti North, Waikouaiti South in 2019/2020 and 2020/2021.

We completed aerial control in:

  • the Silver and Sister Peaks area during the 2016/2017, and
  • Shag Forest in 2020/2021.

Current state

There are currently no infected herds in this TMA.

If you're moving animals

The East Otago TMA is in the Coastal/Central Otago Movement Control Area (MCA). Before you move cattle or deer to another herd or farm, you must have them tested for bovine TB.

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 East Otago 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.
