Biosecurity

If harmful pests and diseases get into New Zealand, they can cause damage. Biosecurity focuses on stopping them at the border or getting rid of the ones already here. 

The lead agency responsible for ensuring New Zealand's biosecurity is the Ministry of Primary Industries (MPI) and their website is the first place you should visit for further information

Mid Canterbury's economy is heavily reliant on the health of our agriculture sectors and our beautiful landscapes are home to a wealth of native flora and fauna. We all have the responsibility for taking practical steps to reduce the risk of spreading diseases and other biosecurity threat.

Some of the current risks for Mid Canterbury are:

High pathogenicity avian influenza (HPAI) also known as bird flu – is a viral disease that is affecting domestic and wild birds around the world.

In 2023, the H5N1 strain of the virus was detected in the southern hemisphere. Since then, it has spread down through South America to the sub-Antarctic islands and the Antarctic peninsula near South America. However, New Zealand, Australia and the Pacific are currently free of HPAI.

HPAI viruses cause high mortality in poultry (chickens, turkeys and quail), and waterfowl (ducks, geese and swans). If HPAI arrived here, these would likely be the most affected domestic species.

Once in New Zealand, it could spread by direct contact between infected and healthy birds, or through contaminated equipment and materials, including water and feed. If HPAI arrives here, cooked food will still be safe to eat. There is no evidence that eggs or chicken meat, or foods that contain them, are unsafe to eat if they are properly cooked.

Signs to look out for:

The most obvious sign of HPAI is sudden death in several birds. Other signs in birds can include:

  • weakness and trembling
  • paralysis
  • difficulty breathing
  • lack of co-ordination
  • blindness
  • diarrhoea.

Poultry shows more severe signs than wild birds. These include lethargy, reduced appetite, droopy head, darkened or swollen comb/wattle, panting, and nasal secretions, unusual drop in egg production, and bleeding disorders.

How to report suspected cases of avian influenza

If you see three or more sick or dead wild birds in a group, report it immediately to Biosecurity New Zealand’s Exotic Pest and Disease Hotline on 0800 80 99 66. Do not handle the birds.

Mycoplasma bovis (M. bovis) is a bacterial disease that creates an animal welfare and productivity issue. It can cause serious health conditions in cattle, including mastitis (udder infection), pneumonia, arthritis, and ill-thrift in calves. Less commonly, it can cause progressive neurological disease in calves, conjunctivitis, and reproductive losses.

M.Bovis in Mid Canterbury

M.bovis was first found on in farm in South Canterbury in 2017 but may have been spreading for some time before that. The disease spread across various regions of New Zealand including farms within Mid Canterbury.

In 2018 the Ministry for Primary Industries (MPI) launched a 10- year eradication programme, which is still ongoing.  As of September 2024, the programme is on track and there are no active confirmed properties in New Zealand. If this ambitious target is met, New Zealand will be the first country in the world to successfully eradicate the disease.​
