Call for expressions of interest to deregulate some organisms

We are seeking input on which new organisms should no longer hold regulatory status as “new” because they are effectively resident in Aotearoa New Zealand.

This deregulation process is conducted under the Hazardous Substances and New Organisms (HSNO) Act, for species that arrived after 29 July 1998 and are now established in Aotearoa.

Proposing a candidate does not guarantee a change in its regulatory status. Organisms are assessed on a case-by-case basis and, once the Minister for the Environment has decided on a shortlist, further public consultation will take place. Ultimately, Cabinet makes the final decision on deregulation.

More information about the process to change the status of a new organism

Once we’ve received proposals, we'll consider whether:

  • the new organism has formed a self-sustaining population in New Zealand
  • any person is attempting to manage, control or eradicate the new organism under any Act
  • changing the status of the new organism is in accordance with the purpose and principles of the HSNO Act.
