New Zealand New Zealand Publishes Order Amending Schedules 1AA and 2A of the HSNO Act

Ban on Chlorpyrifos, LC-PFCAs, and MCCPs

New Zealand Publishes Order Amending Schedules 1AA and 2A of the HSNO Act

On September 7, 2026, New Zealand published the Hazardous Substances and New Organisms (Schedules 1AA and 2A) Order 2026. The order will come into effect on October 9, 2026. It adds chlorpyrifos (CAS Registry Number: 2921-88-2), long-chain perfluorocarboxylic acids (LC-PFCAs), and medium-chain chlorinated paraffins (MCCPs) to Schedule 1AA, Stockholm Convention on Persistent Organic Pollutants, and Schedule 2A, Persistent Organic Pollutants, of the Hazardous Substances and New Organisms Act 1996 (HSNO Act). However, the addition of chlorpyrifos to Schedule 2A will take effect on July 8, 2027, while the addition of LC-PFCAs and MCCPs to Schedule 2A will take effect on December 16, 2026. Unless they fall under the exemptions specified in Schedule 2A, the import, manufacture, use, or storage of these three substances in New Zealand will be prohibited from their respective effective dates. The order also updates the existing entry for UV-328 in Schedule 2A of the HSNO Act to reflect new exemptions adopted at the 12th Conference of the Parties to the Stockholm Convention on Persistent Organic Pollutants in May 2025.

The exemptions specified in Schedule 2A for the three newly added substances are detailed below. Please note that no manufacturing exemptions have been established for any of the three substances.
