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 equipment there are requirements you must meet.


9 August 2018 – New IHS for vehicles, machinery and equipment

The Ministry for Primary Industries (MPI) issued the new import health standard (IHS) and related guidance document. The IHS comes into force on 1 September 2018.

To help manage the risk of BMSB infestation, we've revised the IHS for sea containers (with chief technical officer directions).

BMSB measures for target risk goods

If you're importing break-bulk (not in a container) or containerised sea cargo from certain countries, you must meet certain MPI requirements to manage the risk of brown marmorated stink bugs (BMSB) getting into New Zealand. MPI has changed the list of countries that need to meet these requirements in Schedule 3 of the new IHS issued on 9 August 2018 to:

  • Austria
  • Bulgaria
  • France
  • Georgia
  • Germany
  • Greece
  • Hungary
  • Italy
  • Liechtenstein
  • Romania
  • Russia
  • Serbia
  • Slovenia
  • Spain
  • Switzerland
  • the USA. 

MPI targets imported goods that have a higher risk of carrying the BMSB. These goods include new and used vehicles, vessels, machinery, and equipment which:

  • must be cleaned and treated before shipment if from Schedule 3 countries
  • must be cleaned and treated to control BMSB (and other pests) if from Japan
  • may be inspected on arrival in New Zealand if from a country of concern for BMSB.

You must provide documentation to MPI showing your goods meet the requirements of the IHS for Vehicles, Machinery and Equipment. The definition of vehicles and machinery is broad – check which goods are included in the IHS.

All containerised goods from Schedule 3 countries are at risk of carrying BMSB and may be inspected during the BMSB season.

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.

Requirements for target risk goods

If you're importing vehicles, machinery, or equipment you must meet the following 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.

About BMSB

Our fact sheet contains information about the potential impact that BMSB could have in New Zealand.

Who to contact

If you see insects on imported goods, report them either:

  • directly to a quarantine officer
  • to MPI on 0800  80 99 66
