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 or wildlife. Each TMA has a specific TB control plan designed to eradicate TB as effectively as possible.
The Manuherikia TMA comprises 250,000 hectares across the Manuherikia and Ida Valleys.
North Rough Ridge forms the eastern boundary and the Dunstan Mountains make up the western boundary. The TMA runs from the Hawkdun range at its northern point down to Alexandra at its southern point.
TB infection was widespread in the Manuherikia TMA between 1988 and 2011, with 87 infected cattle herds discovered in this period. After 5 years of ground control and 4 years of wildlife surveillance, the TMA was considered TB-free from 2019.
However, a routine test in 2024 confirmed TB in a cattle herd in Saint Bathans. As a result, we restarted ground control in 2025.
As of January 2025, there is 1 infected herd in the Manuherikia TMA.
The Manuherikia TMA is in the Central Otago Annual Special Testing Area. In these areas, cattle over 12 months and deer over 15 months of age are tested annually.
We will also do targeted tests on selected herds.
We plan our pest control operations up to 3 years in advance. The current year runs from July 2024 to June 2025.
Dates and control methods for pest control operations in Manuherikia 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:
