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 Westland TMA

The Westland TMA covers 114,830 ha between the Taramakau and Hokitika Rivers. The area includes Waimea Forest, Hokitika township and south to the Totara Lagoon, Kumara, Kawhaka, Arahura, Lake Kaniere, Kokatahi and Kowhitirangi.

The habitat is farmland interspersed by steep terraces and ridges covered with native and exotic forest and scrub. Altitudes range from sea level to 1450 metres.

History of TB and pest control in Westland TMA

The Westland TMA has a long history with TB infection in both local wildlife and cattle herds. TB infected wildlife has historically been found along the Hokitika River, along the bush edge of Kokatahi and in the Arahura Valley. There have been many infected herds in this area in recent times because of wildlife-related infections.

We completed ground-based possum control in:

  • the Milltown North, Kokatahi and Kowhitirangi areas in 2016
  • the Hokitika South, Taipo, Arahura and Kumara Junction areas in 2018
  • Arahura, Hokitika, Hokitika South, Kokatahi West, Kowhitirangi West, Kumara Junction, Milltown North and Taipo in 2019/2020
  • Arahura, Hokitika South, Kowhitirangi West, Kumara Junction, Milltown North and Kokatahi West in 2020/2021

We undertook:

  • possum population assessments in Taipo South, Turiwhate and Kowhitirangi in 2016/2017, and
  • pig surveys in Kumara and Turiwhate in 2019/2020 and 2020/2021.

Aerial operations date back to 2011 in the Blue Spur area and 2012 in The Hokitika West and Kokatahi areas.

Current state

There are currently no infected herds in the Westland TMA.

If you're moving animals

The Westland TMA is in the West Coast 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 Westland 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.
