Treatment suppliers

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.

Requirements for treatment suppliers

General requirements for approved treatment suppliers are set out in the MPI standard Treatment supplier programme.

Imported seed fungicide treatment suppliers are approved under the Standard for transitional facilities for general uncleared risk goods (TFGEN).

Some export treatment suppliers (such as for seeds and timber) are approved under plant export standards.

Treatment options

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 aerosol sprays for sea container facilities

The following dual action aerosol spray insecticides meet the requirements of transitional facilities for sea containers.

  • Black Flag lemon – low irritant fly and insect killer
  • MAC Slay – residual insecticides
  • Mortein Fast Knockdown Multi Insect Killer
  • Raid Multipurpose Insect Killer odourless
  • Raid odourless commercial.

If you see live insects in a container, spray insecticide in the container to prevent them from escaping. Spray for about 12 seconds for a 20-foot container (based on 1% active ingredient), then shut the door.

Call MPI's pest and diseases hotline to report the insects and get advice on what to do.

  • Phone 0800 80 99 66.

If your facility has to meet food safety requirements for chemicals, these take precedence over aerosol spray requirements of transitional facilities. To have your spray assessed for suitability, email standards@mpi.govt.nz.

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.
