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 Hari Hari TMA covers 42,700 hectares north and east of the Poerua River and south of the Waitaha River. The area includes flat, predominantly dairy country and the Hari Hari township.

The habitat type is farmland interspersed with moderate hills covered with mature podocarp forest and areas of scrub. Altitudes range from sea level to 350 metres.

History of TB and pest control in Hari Hari

The Hari Hari TMA has a long history of TB infection in local wildlife and cattle herds. Cattle herd infections have been linked to local wildlife TB infections in deer and possums.

We completed aerial possum control in the:

  • Karnbach and Poerua blocks in 2018, and
  • Ianthe and One One blocks in 2021.

We undertook ground-based possum control in Hari Hari in 2019/2020, 2021/2022, and 2022/2023.

Current state

As of June 2023, the Hari Hari TMA has 4 infected herds. We are carefully managing the infection under a special OSPRI programme.

If you're moving animals

A Movement Control Area was put in place for Hari Hari on 9 February 2021 to prevent the spread of TB into other areas. 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 2023 to June 2024.

Dates and control methods for pest control operations in Hari Hari 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.
