The government has made it compulsory for New Zealand poultry farmers with more than 100 birds to have a plan to deal with bird flu. Biosecurity Minister Andrew Hoggard announced the new rules on 28 July 2026, confirming that H5 bird flu has arrived in New Zealand and will "almost certainly establish in wild birds" (RNZ).

The rules apply to any poultry operation with more than 100 birds. Each farmer must write a plan setting out how they will prevent and manage bird flu, and register it with the Ministry for Primary Industries (MPI). Farmers will also need to keep records, carry out checks, and have clear plans for humane culling, disposal, cleaning, and disinfection if their birds are affected (RNZ).

MPI calls these plans an "avian biosecurity control programme" (MPI). The ministry asked for public feedback on the proposed rules in late 2024 and received 36 submissions, which were broadly supportive. The rules will now be written up and shared with industry groups before coming into force by the end of 2026 (RNZ).

The announcement follows confirmation of a second case of H5N1 in New Zealand, reported on 17 July 2026 (Beehive). A government official said at the time that bird flu "cannot be eradicated" and that the country "will have to learn to live with" it. There is currently no evidence of mass deaths in wildlife from bird flu in New Zealand (MPI).

The government and the poultry industry have also signed an agreement to work together on preparing for and responding to bird flu (Beehive). MPI says its bird flu programme aims to reduce impacts on the poultry sector and protect New Zealand's chicken and egg supply (MPI).

Hoggard said MPI is available to help farmers, especially smaller operators, with biosecurity practices (RNZ). MPI says the rules will allow egg and chicken producers across New Zealand to make informed decisions about how best to protect their flocks (MPI).

In practical terms, MPI already advises commercial poultry farmers to limit visitors to necessary people only and restrict their access to sheds and other bird areas (MPI). It also recommends that bird owners make enclosures birdproof by repairing or blocking holes and keep birds away from open ponds, lakes, creeks, or other water (MPI). These measures are consistent with the types of controls the new mandatory plans will need to formalise.

Until now, biosecurity measures for New Zealand poultry farmers have been voluntary, meaning farmers could follow MPI's guidance but were not legally required to do so. The new rules bring poultry into a formal system with registration, record-keeping, and audit obligations, similar to how other animal diseases are managed under the Biosecurity Act.

The 100-bird threshold means commercial and semi-commercial operations are covered, while very small backyard flocks are not. Hoggard's emphasis on MPI support for smaller operators signals awareness that smaller farmers may face more practical challenges meeting the new requirements than large-scale producers who already have biosecurity systems in place.

The timeline matters for industry planning. The rules do not come into force until the end of 2026, giving industry bodies time to shape the drafting and farmers time to prepare. But with H5 already confirmed in New Zealand and the minister's assessment that it will almost certainly establish in wild bird populations, that window is for preparation, not waiting. Because wild birds carry the virus, the threat is ongoing, and the rules are being designed around managing a long-term risk rather than containing a one-off outbreak.

The broader context is that the Cabinet sign-off and the joint government-industry agreement point to a coordinated response across both the public and commercial spheres. The broadly supportive consultation response, 36 submissions with no significant opposition reported, suggests the sector is aligned with the direction of the new rules, which reduces the likelihood of industry pushback during the drafting phase.
