New Zealanders have been asked to be alert after a single ocean-going seabird, a brown skua, returned a confirmed positive test for H5 bird flu after it was found on Petone beach in Wellington.
H5 bird flu is a low health risk to the public as it rarely affects humans unless there is direct, close, and prolonged contact with large numbers of sick birds. Eggs and poultry remain safe to eat.
The detected case is the concerning H5 bird flu strain (H5N1 avian influenza clade 2.3.4.4b) that has been circulating globally and is the first detection in New Zealand.
“This is a coastal detection in an individual ocean-going seabird, and there is no evidence of any mass mortality in wildlife or transmission between wild birds in New Zealand. There has been no detection in poultry,” said Biosecurity Minister Andrew Hoggard.
“The situation is being closely monitored, but at this stage, there is no evidence of any illness beyond this seabird. We’ve had people out on Petone beach checking and found no other issues. We will continue to monitor the beach and surrounding areas.”
The government has asked the community to be alert and follow advice on reporting sick or dead birds, and said it was vital that people do not touch or handle unwell birds.
The Ministry for Primary Industries (MPI) will continue its wider surveillance and work closely with industry, veterinarians, and wildlife carers.
New Zealand is well prepared to respond to H5 bird flu and will work to protect poultry production and reduce impacts on wildlife and communities.
“MPI, the Department of Conservation, the Ministry of Health, and Health New Zealand have been working together with industry and local councils to get ready. Our response is designed to manage the risks of H5 bird flu, to protect poultry production, and reduce impacts on wildlife and communities.”
MPI has been working with the poultry industry to develop biosecurity and resilience plans, to create industry preparedness for when H5 bird flu arrives.
In September 2025, a Government Industry Agreement (GIA) formally established the Poultry Council to oversee the delivery of a joint readiness work programme between MPI and industry. This programme has aimed to minimise impacts on the poultry sector and safeguard New Zealand’s chicken and egg supply.
At present, MPI has been testing birds every few days through reports and targeted wildlife surveillance. While there have been no detections in poultry, producers were reminded that on-farm biosecurity practices are crucial to protecting their flocks' health. Eggs and poultry meat remain safe to eat.
Australia has recently reported single birds testing positive for H5 bird flu in coastal areas, with no reports of mass mortalities, and Hoggard said there may be a similar pattern here.
"We are continuing to act early and prepare carefully, while asking the community to remain watchful and report three or more sick or dead birds in a group to the MPI pest and disease hotline."
DOC has started a vaccination programme for 300 core breeding birds from five of its most endangered birds - kākāpō, takahē, tchūriwat/tūturuatu/shore plover, kakī/black stilt and kākāriki karaka/orange-fronted parakeet.
