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 Taharua TMA

The Taharua TMA lies in the Hawke's Bay section of the Taupō District, to the west of the Napier-Taupō Highway.

The TMA is a mix of:

  • native bush (Kaimanawa Forest Park)
  • pine plantations, and
  • intensively managed pasture land.

The adjoining Taharua area has little habitat. There are only a small number of herds in this TMA – these are large dairy and beef herds. There's also deer breeding herds and a game estate in the Poronui area.

History of TB and pest control in Taharua

This TMA has a long history with TB infection in cattle herds. We've identified several infected herds in the Taharua area over the last 10 years. We've also found infected wildlife - most recently a ferret in 2003, and a pig in 2008.

Previous possum control and livestock disease management has reduced the number of infected herds in the Bay of Plenty region. However, our monitoring has shown that we need to do further control work in the Whirinaki 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've completed regular possum control operations in the Taharua TMA since the early 2000s. This has kept the possum population at a low level, and has prevented TB from migrating into the TMA from neighbouring areas. Our most recent control in this area was ground control in 2021, in the Lochinver area and in land directly east of Lochinver.

Current state

There are no infected herds in the Taharua TMA.

If you're moving animals

The Taharua TMA is in the Central North Island 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 Taharua 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.
