We've a bare-bones report today from New Zealand's Ministry for Primary Industries on that country's first detection of H5N1, which come less than a month after Australia's first report.
While the bird species isn't specified (`ocean going sea bird'), and no collection dates are provided, this suggests the eastward spread of H5N1 across more than 3,300 miles of oceania in a matter of a few weeks.
The official statement follows:
SITUATION UPDATE: 15 July 2026
A single ocean-going sea bird has tested positive for H5 bird flu in New Zealand.While this was fully expected after the arrival of the virus to mainland Australia (see New Zealand: DOC to vaccinate ‘at risk’ birds against bird flu), it is disappointing how quickly the last H5-free dominos on earth are falling.
The bird was found on Petone Beach in Wellington and reported to our exotic pest and disease hotline. Subsequent testing confirmed H5 bird flu (H5N1 avian influenza clade 2.3.4.4b).
This is the first detection of H5 bird flu in New Zealand. It hasn't been found in any other birds and there are no detections in poultry.
The risk to human health remains low.
New Zealand is well prepared to respond and will react quickly to protect poultry production, and to reduce impacts on wildlife and communities.
H5N1 marches on.
