Treatment suppliers must be approved to the appropriate MPI standard to treat imported goods, or exported plant or forest products. Find out about approved treatment suppliers, treatments and the supplier approval process.
Approved treatment suppliers
Treatment suppliers must be MPI-approved to treat:
- imported risk products for biosecurity clearance
- products for export to meet destination country requirements.

Becoming an approved treatment supplier
To become an approved treatment supplier, you need to apply through an independent verification agency (IVA).
Contact one of the following agencies that are approved by MPI to evaluate treatment suppliers for MPI-approval:

Some export treatment suppliers (such as for seeds and timber) are approved under plant export standards.
For imported goods that need treatment to get border clearance, MPI provides a list of treatment options (and importer responsibilities) in the standard Approved biosecurity treatments.

Goods being treated for export may have different requirements from imported goods. Check requirements for exported plant products in the relevant importing country phytosanitary requirements (ICPR).
Suitable insecticide aerosols have at least one knock-down and one residual active ingredient from Table 1. To ask about the suitability of a particular aerosol or an active ingredient not listed in the table, email email@example.com
Table 1 Suitable active ingredients for insecticide aerosols
(minimum single or combined amount 1g/kg or 0.1%)
Note: bicycloheptene dicarboximide and piperonyl butoxide are propellants or synergists and do not have insecticide properties.
If you see live insects in a container, spray insecticide in the container to prevent them from escaping. If you suspect that a container is infested with multiple insects, spray insecticide aerosol toward the top of the container for a minimum of 12 seconds (based on a 20 foot container) before closing it for at least 30 minutes. To kill a single insect, spray the aerosol directly onto the insect for as long as it takes to kill it.
Call MPI's pest and diseases hotline to report insects and get advice on what to do.

If your facility has to meet food safety requirements for chemicals, these take precedence over aerosol spray requirements of transitional facilities.
Methyl bromide treatment
Because it is an ozone-depleting substance, methyl bromide can be used only for official quarantine and pre-shipment treatments.

Offshore treatment suppliers
Some imported products need to be treated by offshore treatment suppliers to prevent introduction of pests and diseases into New Zealand. Offshore treatments are listed in the relevant import health standard.
Australian Fumigation Accreditation Scheme
The Australian Fumigation Accreditation Scheme (AFAS) provides a list of 'acceptable' registered offshore treatment providers which MPI recommends you use for offshore treatment (including Malaysian fumigation providers which have improved compliance).
New Zealand is moving towards a requirement to use only registered treatment providers for offshore treatment of goods. When in place, importers may have additional costs at the border if non-registered treatment suppliers have been used.
If you are importing products from overseas that require treatment prior to entry to New Zealand, check the AFAS list of offshore treatment suppliers.
