A case of the highly infectious H5N1 strain of avian influenza, commonly known as bird flu, has recently been confirmed in New Zealand. It’s understandable that this has raised questions from pet owners, poultry keepers, and farmers across Canterbury – so here’s what we know, and what it means for our community here in Geraldine, Timaru, and Fairlie.

The Current Situation

At this stage, only a small number of cases have been recorded in wild birds, with the first detection identified in a seabird in Wellington. Importantly:

• There is no evidence of spread within poultry flocks
• There is no large-scale event in wildlife
• The risk to human health remains very low
• Eggs and poultry products remain safe to eat

The Ministry for Primary Industries and Biosecurity New Zealand are actively monitoring the situation, with ongoing surveillance and testing across both wild bird populations and poultry systems. Early detection and strong biosecurity are the two biggest tools we have to keep any impact to a minimum, based on what’s been seen overseas in previous outbreaks.

How Bird Flu Spreads

H5N1 primarily spreads through:

• Direct contact with infected birds, particularly wild waterfowl and seabirds
• Contaminated environments – faeces, water, equipment, and clothing
• Movement of people, animals, or equipment between properties

Wild birds, especially coastal and migratory species, remain the key pathway for the virus entering New Zealand – something worth keeping in mind for anyone with a lifestyle block or farm near the coast or waterways.

Protecting Pets, Poultry, and Farm Animals

The risk to pets, poultry, and farm animals across Canterbury remains low, but a bit of preparation goes a long way. We recommend:

• Preventing contact between domestic birds and wild birds
• Keeping feed and water sources covered
• Maintaining strict hygiene for boots, gear, and vehicles moving between properties
• Monitoring animals closely for any signs of illness
• Reporting any unusual sickness or deaths promptly

If You Find Sick or Dead Birds

If you come across multiple sick or dead birds in one area:

• Do not touch or handle them
• Keep pets and people away from the area
• Report it immediately to the Exotic Pest and Disease Hotline: 0800 80 99 66
