Avian Influenza (Bird Flu)
August and September are high risk months for the potential arrival of H5N1 Highly Pathogenic Avian Influenza (HPAI), otherwise known as bird flu. Both wild and farmed birds are at risk. But it is not just birds; there has also been transmission to seals, pigs and even people working closely with infected animals in other countries.
While the H5N1 strain of bird flu is not yet in New Zealand, Australia or the Pacific Islands, it is present in Antarctica. Detection of its arrival in Aotearoa may not be immediate. It is important that you take a precautionary approach to any dead wildlife that you come across.
Signs of bird flu vary but indicators include tremors, twisting/arching neck, weakness, paralysis, difficulty breathing and diarrhoea.
If you see three or more birds, marine mammals or other wildlife displaying these symptoms, or three or more dead animals together, please report it to the Biosecurity New Zealand Exotic Pest and Disease hotline: 0800 80 99 66.
Do not handle sick or dead birds if you suspect bird flu.
Please refer to the Biosecurity New Zealand factsheet below for key information.
