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 Grey TMA

The Grey TMA covers 99,224 ha 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 Ranges.

The habitat is narrow strips of farmland interspersed by moderate to high hills covered with nature podocarp bush and scrub areas. Altitudes range from sea level to 1200 metres on the Hohonu Range.

There are 137 herds in this TMA.

History of TB and pest control in the Grey TMA

In 2007, TB-infected possums were found behind Greymouth at Boddytown, and a TB-infected pig was identified from the Hohonu Range in 2009/10.

Over more than 10 years we have completed ground-based possum control throughout the entire area.

We undertook aerial control in:

  • Moana North aerial in 2011
  • Hohonu aerial, Marsden East aerial and Te Kinga aerial in 2012
  • Kaiata South block in 2013.

Current state

There are currently 1 infected herd in the Grey TMA.

If you're moving animals

The Grey TMA is in the West Coast Movement Control Area. 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 Grey 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.
