New Zealand vaccinates endangered birds against HPAI
2 September, 2025
New Zealand has carried out a world-first vaccination program to protect its most endangered native bird species from avian influenza. The Department of Conservation trialed the Poulvac Flufend RG vaccine, an inactivated H5N3 vaccine, in kākāpō, takahē, kakī (black stilt), tūturuatu (shore plover), and kākāriki.
Most species developed strong and lasting antibody responses, although kakī showed weaker protection, suggesting adjustments may be required. Authorities stress that vaccination is intended as an added safeguard alongside strict biosecurity. Neighboring Australia is monitoring the trial as it considers similar measures for its own threatened species.
