From 1 January 2026, in addition to the business information you currently need to provide, all importers and manufacturers of hazardous substances will need to provide:

• your New Zealand Business Number (NZBN) if you have one
• the HSNO approval number or group standard number(s) for each hazardous substance you are importing or manufacturing.

You’ll need to notify us within 30 days of first importing or manufacturing each hazardous substance. Any changes to your business information, such as a new point of contact, business address, or other relevant details, also need to be reported within 30 days.

If you’ve already provided this information and meet your responsibilities under the current Hazardous Substances (Importers and Manufacturers) Notice, you’ll need to use the new
online portal to resubmit this information from 2026. This helps ensure that information in the new online portal is up to date.

Annual reporting for certain chemicals

If you import or manufacture certain hazardous substances, you’ll need to submit an annual report to the Environmental Protection Authority (EPA). The first reports, covering activity
during the 2025 calendar year, will be due between 1 January and 31 May 2026. Start keeping records now to ensure you’re ready.

Substances requiring annual reporting include:
• agrichemicals (eg pesticides, fumigants, plant growth regulators, vertebrate toxic
agents)
• selected veterinary medicines*
• timber treatment chemicals
• antisapstain chemicals
• antifouling paints.
*Only parasiticides used in large commodity animals (eg sheep, cattle, goats, horses) are
included.
You do not need to provide this information for:
• fertilisers
• methyl bromide**
• EDN**
• any substance imported or manufactured in accordance with a containment approval
issued under section 32 of the HSNO Act.

**These substances have separate reporting requirements under the HSNO Act.

What you’ll need to include in your annual report

Substance details:
• the product name
• the chemical category
• HSNO approval number or group standard title.

For each product, details of the active ingredient(s):
• the name
• CAS number (if applicable)
• total quantity (kg) in formulated products.

You’ll need to identify each product and report the amount of active ingredient contained in that product that was imported or manufactured over the previous calendar year.

Just relabeling or repacking? The annual reporting requirement doesn’t apply to you 

The reporting requirement applies to those who import these designated hazardous substances from overseas or manufacture them in New Zealand. In cases where the
substances are relabelled, the original importer is responsible for reporting to avoid double counting.
