Bird flu has been found in New Zealand for the first time, after a wild seabird picked up on a Wellington beach tested positive for the H5N1 strain that has swept through wildlife populations across the rest of the world.
The bird was a brown skua, a large ocean-going seabird known in te reo as hākoakoa. It was found by a member of the public on Petone Beach on the northern shore of Wellington Harbour and taken to Wellington Zoo, where staff noticed it was behaving oddly. Testing confirmed the H5N1 result, and the Ministry for Primary Industries announced the detection on Wednesday.
Biosecurity Minister Andrew Hoggard sought to reassure the public while confirming the milestone, saying the case was an isolated one so far. “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,” he said in a statement. “The situation is being closely monitored, but at this stage there is no evidence of any illness beyond this seabird.”
The strain confirmed in the skua is H5N1 clade 2.3.4.4b, the same lineage that has killed tens of millions of wild birds, poultry and marine mammals on every other continent over the past few years. New Zealand and the wider Pacific had until now been the last significant part of the world untouched by it. The arrival had been widely expected, with authorities warning for months that migratory and ocean-going birds could carry the virus across the Southern Ocean.
MPI Chief Veterinary Officer Mary van Andel said the skua had stood out to the people who found it because of its condition. “It wasn’t reacting as you would expect a wild bird to do,” she told RNZ. Skuas are powerful, aggressive birds that scavenge and prey on other seabirds, which makes them one of the more likely species to encounter and spread the virus.
The response is being coordinated across MPI, the Department of Conservation, the Ministry of Health and Health New Zealand. Surveillance testing of wild birds is being stepped up, Petone Beach and the surrounding coastline are being monitored, and officials are working with poultry farmers on biosecurity plans to keep the virus out of commercial flocks. New Zealand has around 12 million farmed birds, and no infection has been found in any poultry operation.
For most people the risk is low. Bird flu very rarely infects humans, and does so only after direct, close and prolonged contact with large numbers of sick birds. Health officials say eggs and poultry meat remain completely safe to eat. The advice to the public is practical rather than alarming. People are asked not to touch or move sick or dead birds, and to report any sighting of three or more sick or dead wild birds to the MPI hotline on 0800 80 99 66, ideally with a location and a photograph.
The greater worry is for native wildlife. New Zealand’s isolation has produced birds found nowhere else on earth, many of them already clinging on in tiny populations, and they have no prior exposure to this virus. Overseas the strain has wiped out as much as 90 percent of some seabird colonies. Massey University infectious disease epidemiologist Nigel French said the stakes for the rarest species could not be higher. “If it were to get into some of the small endangered populations, particularly of seabirds like the fairy tern, there’s a very few of those in New Zealand, then it could result in an extinction of those particular species,” he told 1News. He noted the virus does not respect species boundaries, affecting wild animals, farmed animals and marine mammals alike.
The Department of Conservation has been preparing for this moment for some time and has already begun vaccinating around 300 core breeding birds across five of the most vulnerable species, among them the kākāpō, the takahē, the shore plover, the kakī or black stilt, and the orange-fronted parakeet. These are birds where the loss of even a handful of individuals could set back decades of recovery work. DOC biosecurity technical advisor Suliana Teasdale said the department was working in unfamiliar territory. “We have quite unique fauna, and marine mammals and birds, so it could be quite different, but we’re just being prepared,” she said.
The confirmation has already had knock-on effects. A Wellington bird hospital, Flock Birdcare, has stopped accepting sick or injured seabirds while the situation is assessed, to avoid the risk of an infected bird passing the virus to others in its care. Conservation groups are asking members of the public to keep dogs away from beaches where dead birds have washed up, and to keep their distance from seal and sea lion haul-outs, since marine mammals overseas have also died from the strain.
For the poultry sector, the focus is firmly on keeping the virus outside the farm gate. Industry representatives say the emphasis is on tighter biosecurity checks, keeping wild birds away from sheds and feed, and watching flocks closely for any sign of illness. A single detection in commercial poultry would trigger a much larger response, including movement controls and culling, so the industry is treating the skua case as a warning to lift its guard rather than a cause for panic.
Officials have been careful to frame the detection as the beginning of a long haul rather than a crisis point. The virus is now almost certainly here to stay, carried by wild birds that move freely along the coast and between islands, and the country’s task is to slow its spread, protect the species most at risk, and keep it out of farmed flocks and, as far as possible, out of people. For a nation whose identity is bound up with its birds, from the kiwi on the coins to the dawn chorus in the bush, the arrival of a virus that has emptied colonies elsewhere lands as more than a biosecurity headline.
