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 and machinery, there are requirements you must meet.


BSMB measures for target goods

To reduce the risk of brown marmorated stink bugs (BMSBs) getting into New Zealand, MPI targets imported goods that have a higher risk of carrying the pest. These goods include new and used vehicles, vessels, and machinery which:

  • must be treated if shipped from the USA or Italy during the BSMB season
  • may be inspected if from a country of concern for BMSB.

You must provide documentation to MPI showing your goods meet the requirements.

The definition of vehicles and machinery is broad – check which goods are included in the Import Health Standard (IHS) for vehicles, machinery and tyres.

All containerised goods from Hungary, Italy, and the USA are at risk of carrying BMSB and may be inspected during the BMSB season.

BMSB season – when the measures apply

The treatment requirements apply to target goods shipped from:

  • the USA all year round
  • Italy from 1 September 2017 to 30 April 2018 inclusive.

However, MPI plans to make the seasons for the USA and Italy the same in 2018. A new vehicle import health standard is being drafted for consultation in November 2017. It will include the revised season dates.

The requirements for target goods apply for the whole season unless we find BSMB infestations. If this happens, we may apply emergency measures.

Requirements for target goods

If you're importing vehicles or machinery from Italy or the USA, you must meet the following requirements.

BMSB inspections

To make sure the measures to manage BSMB are working, MPI inspects specific goods from Hungary, Italy and the USA (as well as countries of emerging BMSB concern) 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 BSMB in:

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

Voluntary use of trap lights 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.
