Detailed information for treatment suppliers about treatment options (including methyl bromide and insecticide aerosols), treatment supplier standards, and how to get approved as a treatment supplier is on another web page.

  • imported risk products on arrival
  • products for export to meet destination country requirements.

Offshore treatment suppliers

Some imported products need to be treated offshore to prevent the introduction of pests and diseases into New Zealand.

New Zealand is moving towards a requirement to use only registered treatment suppliers for offshore treatment of goods. When in place, importers may have additional costs at the border if non-registered treatment suppliers have been used.

MPI doesn't approve or require approved offshore treatment suppliers for all imports. Check if your product requires an approved offshore treatment supplier in the relevant import health standard (IHS).

Brown marmorated stink bug (BMSB) treatment

Providers in countries listed in Schedule 3 of the IHS for Vehicles, Machinery, and Equipment need to send a completed application form to MPI (even if they're on the Australian stink bug approved list).

We'll accept treatment certificates from providers who haven't registered for a period, but these goods will be subject to increased verification. If you continue to present stink bug treatment certificates throughout the season from providers that haven't been approved by MPI, treated goods may be refused entry, re-exported or destroyed.

MPI is accepting Australian stink bug fumigation certificates for 12 and 24 hour fumigation rates, but the New Zealand heat treatment is different (check page 41 of our Standard: Approved Biosecurity Treatments). 

If you're importing goods from countries that require treatment for brown marmorated stink bugs, we accept those on the Australian Department of Agriculture and Water Resources (DAWR) website.

Approved methyl bromide treatment suppliers

If you're importing from one of the following countries and your goods require methyl bromide treatment, we recommend you use a treatment supplier approved by that country's biosecurity agency.

Check for acceptable methyl bromide treatment suppliers in these and other countries in the Australian Fumigation Accreditation Scheme (AFAS) list. 

Requirements for NZ treatment suppliers

Treatment suppliers in New Zealand must:

  • meet appropriate standards
  • use approved treatment options
  • be MPI-approved.
