Brown marmorated stink bug requirements

MPI is working to reduce the risk of brown marmorated stink bugs (BMSBs) getting into New Zealand. Stink bugs are a serious pest for agriculture and horticulture and can be a social nuisance. If you're importing vehicles, machinery or parts there are requirements you must meet.


On 22 July 2019, we released revised vehicle and sea container import health standards with the 2019-2020 brown marmorated stink bugs (BMSB) season requirements. 

Ensure you are using the latest standard

You must meet requirements under the Import Health Standard for Vehicles, Machinery, and Parts.

And the Import Health Standard for Sea Containers.

MPI has issued the following industry notice to advise of BMSB management changes for Vehicles, Machinery and Parts from BMSB risk countries and sea containers from Italy.

BMSB measures for target vehicles machinery and parts

If you're importing targeted vehicles, machinery or parts from certain countries you must meet certain MPI requirements to manage the risk of brown marmorated stink bugs (BMSBs) getting into New Zealand. The list of countries that need to meet these requirements are in Schedule 3 of the vehicles, machinery and parts IHS issued on 22 July 2019.

These 33 countries are:

Albania Japan
Andorra Kosovo
Armenia Liechtenstein
Austria Luxemburg
Azerbaijan Macedonia
Belgium Montenegro
Bosnia and Herzegovina Netherlands
Bulgaria Romania
Canada Russia
Croatia Serbia
Czech Slovakia
France Slovenia
Georgia Spain
Germany Switzerland
Greece Turkey
Hungary USA

You must provide documentation to MPI showing your cargo meets the requirements of the IHS for Vehicles, Machinery and Parts. If your cargo requires BMSB management under the Standard there is the option of MPI-Approved System management or treatment with an MPI-Approved Treatment before the cargo arrives in New Zealand.

The definition of vehicles, machinery and parts is broad – check which goods are included for BMSB requirements in the IHS by using the specific definitions provided.

BMSB Requirements for Italian sea containers

Sea Containers from Italy must also meet BMSB requirements during the BMSB season. Containers (and inner goods) require treatment with an MPI-Approved Treatment before arrival in New Zealand.

BMSB season – when the measures apply

The risk season is from 1 September until 30 April. Note, MPI may apply emergency measures if we find BMSB infestations.

Is your cargo transshipping via a BMSB-risk country on the way to New Zealand?

Sometimes, new and used vehicles,machinery and parts are manufactured in (or originate from) a 'non-BMSB-risk country', but then get transshipped via a 'BMSB-risk country' on their way to New Zealand. This transshipping may expose the cargo to the risk of BMSB. Because of this, MPI has requirements you need to meet if you're transshipping during the BMSB-risk season (September to April of each year).

We've prepared information to help you understand what you need to do if you're transshipping your cargo through a BMSB-risk country before it arrives in New Zealand.

Is your cargo being treated in a BMSB-risk country?

Target new or used vehicles, machinery and parts from BMSB-risk countries can meet BMSB requirements if they use MPI-Approved Treatments before they arrive in New Zealand. However, there are post treatment conditions which importers also need to meet before MPI will accept the treatment. We've prepared information to help you understand what you need to do if you're treating your cargo in a BMSB-risk country.

Is your cargo transshipping through a non-BMSB risk country on the way to New Zealand for treatment or repacking?

Sometimes new and used vehicles, machinery and parts are manufactured (or originate from) a 'non-BMSB-risk country', then get transshipped via another non 'BMSB-risk country' on their way to New Zealand for repacking or treatment. This may also occur for sea containers from Italy.  If repacking into other FAK container occurs in non-schedule 3 countries (such as Singapore), you will need to ensure the correct country of origin is stated and the correct documents are submitted to MPI. If you plan to treat for BMSB in a non BMSB country, there are conditions to ensure the goods meet MPI’s BMSB treatment requirements.  

BMSB inspections

To make sure the measures to manage BMSB are working, MPI inspects specific goods from BMSB risk countries (Japan and Scedule 3 countries) throughout the season. You also have a legal obligation under the Biosecurity Act 1993 to notify MPI of risk pests, such as BMSB.

Voluntary trapping

Light traps have been effective in previous seasons to help operators quickly find and respond to BMSB. Manufacturers, importers and shipping line operators are encouraged to use traps to monitor for the presence of BMSB in:

  • manufacturing and storage facilities
  • load ports
  • shipping vessels. 

Voluntary use of light traps may reduce the need for verification of the vessel when it arrives in New Zealand. Report any pests to MPI.

How we charge

For all imported goods, MPI charges the owner or importer of the goods for our services, including:

  • processing documents
  • risk assessments
  • inspections.

Extra costs may be incurred if a new infestation of viable BMSB is found on a vessel before goods are unloaded to the wharf.

Resources for the risk season

Biosecurity New Zealand has 2 documents to help importers, agents, shipping lines, and ports during the BMSB risk season.
