Check treatment requirements for your product in the relevant import health standard.
Approved biosecurity treatments
For goods that need treatment on arrival for border clearance (for example, if insects were found on arrival), check MPI's Standard: Approved Biosecurity Treatments 21 December 2021.
Approved biosecurity treatments [PDF, 1.1 MB]
Check treatment requirements in the relevant:
- importing country phytosanitary requirements (ICPR) for plant products
- overseas market access requirements for other products
For NZ treatment providers
Detailed information for treatment providers about treatment options (including methyl bromide and insecticide aerosols), treatment provider standards, and how to get approved as a treatment provider is on another web page.
If you need a treatment provider in New Zealand, they must be approved by the Ministry for Primary Industries (MPI) to treat:
- imported risk products on arrival
- products for export to meet destination country requirements.

Some targeted imported risk goods need to be treated before arrival in New Zealand to prevent the introduction of pathogens (causing diseases) and live pests. New Zealand requires that only registered treatment providers may be used to conduct offshore treatment of targeted risk goods. Where treatment is required, if break-bulk or containerised brown marmorated stink bug (BMSB) risk goods (targeted for BMSB management) arrive at the New Zealand border without being treated, it is likely that they will not be allowed to be unloaded and they will be shipped out of New Zealand territory. Such actions will be at the importer’s expense.
However, MPI doesn't approve or require approved offshore treatment providers for all imported risk goods. It is recommended that you check whether your imported products require an approved offshore treatment in the relevant import health standard. It is advisable to use a recommended National Plant Protection Organisation (NPPO) treatment provider, where possible.
(The recommendations in the list are specific to treatment application in Cambodia, Fiji, India, Indonesia, Lao PDR, Malaysia, Papua New Guinea, Peru, Philippines, Sri Lanka, Thailand, and Vietnam).
Brown marmorated stink bug (BMSB) treatment
MPI and the Australian Department of Agriculture, Water and Environment (DAWE) introduced the joint Offshore BMSB Treatment Providers' Scheme (the scheme) in the 2018-2019 season. This treatments scheme covers countries that export risk goods to Australia and New Zealand.
The scheme sets out the minimum registration and compliance requirements for approved treatment providers that do BMSB treatments. BMSB treatments cover targeted goods going to Australia and/or New Zealand during the BMSB risk season.
The BMSB treatment rates between the 2 countries have also been aligned to make it easier for shippers, exporters, importers, and treatment providers to comply with the treatment requirements. Treatment providers who meet the scheme requirements will be added to the list of approved offshore BMSB treatment providers by DAWE (as the administrators).
Full details about the scheme including registration and re-registration forms, and approved treatment providers are on the Australian Department's website.
Approved offshore BMSB treatment providers
The approved offshore BMSB treatment provider list does not include treatment providers in Australia or New Zealand. This is because New Zealand bound goods are not permitted to be treated for BMSB in Australia on the way to New Zealand, and vice versa. Treatments can be carried out at tranship ports if unable to be performed at origin.
Treatment providers on the below list are registered under the Offshore BMSB Treatment Providers Scheme and have demonstrated their capacity to conduct BMSB treatments for the 2020-21 BMSB risk season. The list will be updated as required and providers can be suspended so please check before ordering a treatment.
Treatment providers that were registered under the scheme during the 2019-20 BMSB season must complete a renewal application for the 2020-21 season to be included on the approved list of treatment providers.
Treatment options may vary according to the consignment type (suitable for BMSB overwintering) and the packing of a consignment (packed so that heat or fumigation treatment is effective).

Insecticide treatment for water and aircraft (New Zealand only)
The sets out the minimum requirements for performing insecticide treatments on watercraft and aircraft and/or associated packaging imported as cargo for BMSB purposes as per the Approved Biosecurity Treatments Standard VCE1e.

Standards and documents for biosecurity treatments
Treatments applied for biosecurity purposes are part of measures used in managing the risk of introduction of exotic pests and diseases. These treatments are only effective when conducted correctly.
It is important that all treatment providers understand and follow the requirements to effectively treat consignments for import into New Zealand.
Our standards outlining best practice methodologies for applying biosecurity treatments are available below.
Methyl bromide research
Assessment of Methyl Bromide recapture regimes [PDF, 2.8 MB]
The purpose of this project was to investigate the effectiveness of methyl bromide (MeBr) recapture systems currently used in New Zealand. Two recapture systems were evaluated:
- physical system (carbon sequestering of methyl bromide)
- chemical system (uses a proprietary liquid solution to limit the release of gas to the atmosphere).
A direct comparison between the effectiveness of the different recapture systems on logs and sawn timber clearly illustrates the differences in the rate at which the concentrations of MeBr can be reduced in the treated space following fumigation. For logs, the physical system recaptured 90.89% of the available MeBr after just 2 hours of operation, while the chemical system recaptured 47.66% after 4 hours.
Optimise Methyl Bromide Application (MeBr) [PDF, 2.6 MB]
This project consisted of 3 components:
- Collecting baseline data of how MeBr reacts under different environmental and loading conditions.
- Comparison of the location of monitoring lines under ICCBA to other configurations and the impact on MeBr monitoring accuracy.
- The impact of physical barriers to reduce MeBr loss through container floors under various environmental factors (for example, wind and temperature).
