Latest updates

There are currently 6 herds with a TB-infected status in the Hari Hari area, four of these herds have completed a first clear whole-herd test. 

For infected status herds to return to a clear status, 2 clear whole herd tests are required, no less than 6 months apart. These tests may include an additional blood test for part or all of the herd.


At OSPRI, we're responsible for managing the TBfree programme in New Zealand. The main goal of the programme is to achieve:

  • TB freedom in livestock by 2026
  • TB freedom in possums by 2040
  • eradication of TB from all hosts across New Zealand by 2055.

To help us meet this goal, we've implemented a framework of TB Management Areas (TMAs) around the country. TMAs are areas with known TB infection in livestock and wildlife.

Hari Hari is a TMA — we've identified TB in possums, deer and farmed cattle in the area. The infection was first identified through routine on-farm TB testing, and DNA testing indicates the source of the infection as possums from the Wanganui Valley.

The Hari Hari TMA will be subject to a focused programme of work that includes ground-based and aerial pest control activities, wildlife surveillance, and TB testing. Our goal is to eradicate TB from the Hari Hari area by 2033.

Hari Hari movement control area (MCA)

Movement control areas, or MCAs, control how and where livestock can be moved within a TMA area. An MCA was put in place for Hari Hari on 9 February 2021, to prevent the spread of TB into other areas. The MCA affects approximately:

  • 41 dairy herds
  • 18 beef
  • 1 deer herd.

The MCA covers farms between:

  • the eastern Waitaha Valley edge and Kakapotahi River in the East
  • the southernmost area of the Poerua River flat in the South West boundary
  • the Tasman sea to the North
  • the Southern Alps to the South.

The area of the change is about 53,000ha, of which about 22,000ha is farmed land.

If your farm is within the Hari Hari MCA, you need to know that:

  • cattle and deer over 3 months of age will need a clear TB test at least 60 days before moving off your farm
  • cattle and deer moving direct to slaughter do not need to be TB tested
  • animals moving within the MCA to a piece of land you lawfully occupy do not need a pre-movement test unless there’s a different herd with a different herd number on the destination property already
  • if you intend to move or sell your animals, you need to book a pre-movement test for them first. We need you to make this booking at least 14 days before you plan to move the animals. You can book a pre-movement test online, or by calling our Contact Centre on 0800 482 463.

Pest control programme

The TBfree programme aims to achieve TB freedom in possums in the Hari Hari TMA by 2033.

Current operational progress

Disease management programme

We’re working with Hari Hari farmers who have infected herds to implement farm-specific TB management plans, with the aim of returning each herd to TB-free status as soon as possible.

TB testing in Hari Hari

We have an annual TB testing programme already in place for the Hari Hari area. You don't need to book a test with us — we’ll contact you to organise testing.

If your herd has a positive blood test result

  1. 1 Blood will be taken from animals with a TB positive skin test 10-33 days after the read day of the skin test.
  2. 2 Blood test results will be made available the Monday after testing.
  3. 3 Any blood test positive animals will be valued, and OSPRI will organise their transport and slaughter for you.
  4. 4 The herd status will be suspended.
  5. 5 A post-mortem inspection for TB will be done at slaughter.
  6. 6 Any TB lesions found in the post-mortem will undergo initial lab testing.
  7. 7 Samples of lymph nodes may be taken for more in-depth testing.
  8. 8 Initial lab results from TB lesions will be available after 1-2 weeks. It will take 42-90 days to get the results of any in-depth testing of TB lesions and lymph nodes.
  9. 9 A final diagnosis will be made when in-depth results are available. Final culture results can take up to 90 days.

If your herd does have a positive blood test, we’re here to help. Your OSPRI case management team can talk you through selling your animal, and organise transport and slaughter arrangements to clear infection from your herd.

Support and advice for farmers and communities

The health, wellbeing and welfare of farmers is our top priority. For some farmers, a TB infection puts extra strain on farm management. We can help by:

  • giving you regular updates on disease management and eradication progress in the area
  • arranging TB testing for your herd
  • answering your questions — you can contact us anytime by phone or email, and our regional team can visit you on the farm
  • working with Federated Farmers, Beef+Lamb NZ, DairyNZ and Deer Industry NZ to support you.

All farmers and people in charge of animals are legally obliged to update their NAIT account when farming cattle and deer. Not doing so compromises:

  • our biosecurity response and preparedness
  • our food safety
  • effective livestock traceability.

For help and advice on meeting your NAIT requirements, call the OSPRI Contact Centre on 0800 482 463, or email us at

MPI have information available on the different kinds of support available to farmers, including:

  • feed planning
  • government financial support
  • mental health and social support.

Dealing with drought conditions

As work continues to eradicate Mycoplasma bovis, some farmers may be experiencing stress. MPI has information about the support available for farmers affected by Mycoplasma bovis.

While bovine TB can be passed to humans and household pets, the chance of this happening is very low. The best protection is to:

  • make sure all meat is well cooked
  • eat and drink pasteurised dairy products — avoid raw milk
  • keep dogs on-lead in or near bush areas
  • keep cats inside at night
  • don't feed raw possum meat to pets.

Hunting in the Hari Hari area

Warning signs will be placed at all main access points to aerial pest control areas that are part of the Hari Hari TB programme. All land users, including hunters, must follow the cautions on these signs.

Individual aerial pest control operations will have an associated TB control operation notice. These notices provide instructions to ensure the safety of land users within pest control areas.

For further information on the access permissions and permits required to hunt in the Hari Hari area you’ll need to contact your local Department of Conservation (DOC) office, and the owners of any private property or leasehold in the area.
