Grey TB Management Area (TMA)
Pest control work planned for Grey includes ground control and aerial control.
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 Grey TMA
The Grey TMA covers 99,224 hectares east of Greymouth, between the Taramakau and Grey Rivers. The area includes the Arnold Valley, Lake Brunner, Inchbonnie, Taramakau Valley and Moana Township. Public conservation areas include the Peter Ridge, Mt Te Kinga and the Hohonu Range.
The habitat is narrow strips of farmland interspersed by moderate to high hills, covered with podocarp bush and scrub areas. Altitudes range from sea level to 1200 metres on the Hohonu Range.
History of TB and pest control in the Grey TMA
The most recent wildlife infection in the Grey TMA was a TB-infected pig from the Hohonu Range in 2010.
Since 2012 we have completed ground-based possum control throughout the area. Most recently, we completed ground control in Marsden West, Arnold Valley, Taramakau and Bell Hill in 2023/2024.
We have also completed:
- aerial control in Hohonu, Marsden East and Te Kinga in 2012
- aerial control in Kaiata South in 2013
- pig surveillance in Marsden East in 2023/2024.
Current state
As of June 2024, there are no infected herds in the Grey TMA.
If you're moving animals
The Grey TMA sits across the Tasman/West Coast Movement Control Area (MCA) and the West Coast Kahurangi Annual Special Testing Area (STA). Before you move cattle or deer to another herd or farm from an MCA, you must have them tested for bovine TB. If you're in an STA, you don't need to do pre-movement testing.
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 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.
