New Zealand starts vaccination against endangered species after detecting first H5N1 bird influenza case

Andrew Hoggard, the Biosecurity Minister, announced on Wednesday that New Zealand had reported its first case of deadly H5N1 bird flu after a migratory skua seabird was found near Wellington. The virus was first detected in Australia last month, and the brown skua is the latest bird to be infected. Since 2021, the virulent strain H5 has infected poultry farms and dairy farms and killed?millions of wild birds and mammals.

There is no evidence that there has been a mass death in New Zealand's wildlife or transmission of the disease between wild birds. Hoggard stated that there had been no detection of the virus in poultry.

Hoggard stated that New Zealand could see a pattern similar to the cases reported in Australia, where 14 H5 bird flu cases have been confirmed or presumed as positive by Wednesday.

New Zealand is preparing to deal with H5N1 by working closely with the poultry industry in order to create biosecurity plans and resilience plans.

Hoggard told a press briefing that "we'll be doing more surveillance and testing but, by and large, it's the same work we've done with the industry so far." New Zealand's unique endemic species are particularly vulnerable, as they have evolved without land mammals for millions of generations. This has left many of them flightless and unable to defend themselves from predators.

This isolation made them unique, but it also left them exposed to pests like stoats and rats. Many species already face extinction, and if the virus spreads quickly they are at a high risk. Health officials are launching a vaccination program for?300 breeding birds of?five endangered species in the country, including the flightless takahe (or kakapo).

Hoggard stated that they tested the vaccine last season and saw no side effects, but couldn't be sure how effective it would be as the birds hadn't been exposed to virus.

Brett Gartrell is a professor of wildlife at Massey University. He expressed concern that bird flu might 'push to extinction some of the critically endangered birds in New Zealand.

Gartrell stated that "we are extremely worried about the biodiversity of New Zealand because our birds haven't had to deal before with something like this."

He said, "If the virus spreads rapidly in New Zealand we could be in serious trouble." Reporting by Lucy Craymer, Renju Jose and Kate Mayberry in Sydney. Editing by Sonali Paul, Lincoln Feast and Kate Mayberry.
