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 Kaikoura TMA

A map showing the outline of the Kaikoura TMA.The Kaikoura TMA covers 104,380ha along the coast from Conway to Clarence River. The area includes Kaikoura township and Puhi Puhi Valley. The habitat is varied, and includes:

  • flat, sparsely-treed farmland near the township
  • scrub and native bush areas, at the northern Puhi Puhi Valley end and around Goose Bay
  • steep hills and mountains inland.

Altitudes range from sea level up to the ridge line of the Seaward Kaikoura Range, with peaks between 1400 to 2300m. The lowest pass is approximately 950m.

History of TB and pest control in Kaikoura

The Kaikoura TMA has a long history of TB infection in local wildlife and cattle herds. We've found 2 infected herds in the Kowhai Swyncombe area in the past 5 years.

Previous possum control and livestock disease management has reduced the number of infected herds in the Canterbury/Marlborough region. However, our monitoring has shown that we need to do further control work in the Kaikoura area to reduce the possum population. This will:

  • minimise the risk of the disease spreading through wild animal populations into farmed cattle and deer
  • ensure further good progress towards eradicating TB.

We last completed ground based possum control in 2020/2021 in the Hapuku Buffer and Kowhai Swyncombe areas. We also completed aerial possum control in the Kowahi Swyncombe block in 2016.

Pig surveys were last done in 2020/2021 in the Big Hau and Hapuku Buffer blocks, and in the Oaro block in 2018/2019.

Some areas, such as Big Hau, have had little to no control.

Current state

There are no infected herds in Kaikoura.

If you're moving animals

The Kaikoura TMA is in the Marlborough / North Canterbury Movement Control Area (MCA). That means TB testing is required for cattle and deer before they're moved to another herd or farm.

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 Kaikoura 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.
