South Canterbury High Country TB Management Area (TMA)
Pest control work planned for South Canterbury High Country includes wildlife surveillance.
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 or wildlife. Each TMA has a specific TB control plan designed to eradicate TB as effectively as possible.
The South Canterbury High Country TMA
The South Canterbury High Country TMA covers 232,042 hectares, extending from the Main Divide to between the Two Thumb Range in the north and the Ahuriri River catchment in the south.
The habitat includes high-country river valleys with a mixture of rocky and scrubby habitat, extensive native forest ecosystems in some major valley systems, and improved and intensively farmed flats.
History of TB and pest control in South Canterbury High Country
The South Canterbury High Country TMA has a long history of TB infection. We've found TB in wildlife throughout the TMA for many years, with sporadic infections in cattle herds.
We completed ground-based possum control in:
- Wairepo Creek in 2011/2012 and 2022/2023
- Ahuriri, Dobson, MacKenzie North, Ohau Pukaki and Tasman in 2015/2016
- Ahuriri in 2021/2022 and 2022/2023.
We completed ferret surveys in:
- Dobson in 2011/2012
- Wairepo Creek in 2015/2016
- Ahuriri, Dobson, Mackenzie North, Ohau Pukaki and Tasman in 2023/2024.
We completed a pig survey across the TMA in 2023/2024.
Some areas, such as Hopkins and Huxley, have had very little or no control.
Current state
As of June 2024, there are no infected herds in the South Canterbury High Country TMA.
Future pest control operations
We plan our pest control operations up to 3 years in advance. The current year runs from July 2024 to June 2025.
