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.

Hari Hari TB management area mapThe Hari Hari TMA

The Hari Hari TMA covers 42,700ha 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 by 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 with TB infection in both local wildlife and cattle herds. Historically, cattle herd infections were due to local wildlife TB infections in deer and possums.

We carried out aerial possum control in 2018 in the Karnbach and Poerua blocks.

Ground-based possum control was undertaken in Hari Hari in 2019 and 2020/2021.

Current state

There are currently 9 infected herds in the Hari Hari TMA. The infection is being carefully managed under a special OSPRI programme.

If you're moving animals

A Movement Control Area (MCA) 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 2021 to June 2022.

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.
