Grey North TB Management Area (TMA)
Pest control work planned for Grey North includes ground control and wildlife surveillance.
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 Grey North TMA
The Grey North TMA covers 52,000 hectares of the Grey Valley, between the Paparoa Range and the Inangahua River. The Grey River makes up the southern boundary, with Giles Creek meeting the northern boundary.
Farmland and riparian-strip-type habitat makes up the centre of the TMA, with steep contiguous bush around the edges. Beech is the predominant forest type. Altitudes range from under 200 metres at the river flats to 1200 metres along the western edge.
History of TB and pest control in Grey North
The Grey North TMA has a long history of TB infection in cattle herds. In the late 1990s and early 2000s, 44 infected herds were found.
We completed:
- ground control in Grey Valley North annually between 2009 and 2015, and in 2022/2023 and 2023/2024
- aerial control in Rough River in 2009 and 2015, and in Hukarere in 2011
- wildlife surveillance in Hukarere in 2011 and 2022/2023.
Current state
As of June 2024, there are no infected herds in the Grey North TMA.
If you're moving animals
The Grey North TMA is in the West Coast Kahurangi Annual Special Testing Area (STA). In these areas, cattle over 12 months and deer over 15 months of age are tested annually.
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.
Dates and control methods for pest control operations in Grey North 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.
