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 Remutaka-Hutt TMA

The Remutaka-Hutt TMA runs from Kaitoke in the north, to Pencarrow Head, Baring Head and Turakirae Head in the south. Most of the western boundary is the Hutt River. In the east, much of the boundary is the eastern boundary of the Remutaka Forest Park.

On the eastern side of the TMA are the bush covered hills and mountains of the Remutaka Range. The urban populations of Hutt City and Upper Hutt City are in the west of TMA, which are on the edges of the shrub and gorse covered Eastern Hutt hills. Mangaroa Valley, Whiteman’s Valley and Moores Valley are all included within the TMA.

History of TB and pest control in Remutaka-Hutt

The Remutaka–Hutt TMA has a history of TB in cattle herds since the 1980s. The highest number of infected herds were in the Mangaroa and Kaitoke areas. We've found infected wildlife either in, or very close to, all parts of the TMA.

We've caught a total of 31 infected possums since 1996, with the 2 most recent cases caught in 2012. We've also caught 9 TB infected pigs in the TMA over this time. The 2 most recent were found in the Mangaroa Kaitoke area in 2010 and 2011, but very little surveillance of wildlife for TB has been carried out since.

Previous possum control and livestock disease management has reduced the number of infected herds in the Wellington region. However, our monitoring has shown that we need to do further control work in the Remutaka-Hutt 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 carried out aerial control operations in Orongorongo in 2018, and Mangaroa Kaitoke in 2018 and 2019. We carried out ground control operations in Mangaroa Kaitoke and Wainuiomata South in 2019/2020.

Some areas such as Hutt Valley, Orongorongo, Moores Valley and Wainuiomata South has had very little control in the recent years.

Current state

There are no infected herds in the Remutaka-Hutt TMA at present.

If you're moving animals

The Remutaka-Hutt TMA is in the Wellington 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 Remutaka-Hutt 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.
