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 Molesworth/Clarence Reserve TMA

The Molesworth/Clarence Reserve TMA covers 159,510 hectares west of the southern end of the Inland Kaikoura Range. It includes:

  • part of Molesworth Station
  • the west side of the Clarence Reserve, and
  • the Upper Awatere area.

The habitat is dry grassland interspersed with patches of scrub and bush. Altitudes range from 500 to 2200 metres.

History of TB and pest control in Molesworth/Clarence Reserve

The Molesworth/Clarence Reserve TMA has a long history of TB infection in local wildlife and cattle herds. We found TB-infected possums, ferrets, pigs and deer in 2018 and most recently in 2023.

We completed ground control in:

  • Upper Awatere Molesworth in 2017/2018
  • Upper Awatere and Upper Awatere Molesworth in 2019/2020, 2020/2021 and 2022/2023
  • the aerial exclusion areas in the Molesworth and Bush Gully Vector Control Zones in 2024.

We completed aerial control in:

  • Upper Awatere in 2012/2013
  • Molesworth in 2017, 2021 and 2023.

We completed a ferret survey in Upper Awatere in 2015.

Current state

As of June 2024, there is 1 infected herd in the Molesworth/Clarence Reserve TMA.

If you're moving animals

The Molesworth/Clarence Reserve TMA is in the Marlborough/North Canterbury 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 2024 to June 2025.

Dates and control methods for pest control operations in Molesworth/Clarence Reserve 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:
