Vehicles & machinery

Vehicles and equipment often carry hitchhiking animals like insects or reptiles, which can threaten our environment. MPI's role is to help importers meet biosecurity requirements to keep New Zealand free from harmful pests and diseases.


Treatment requirements for USA imports

From 24 December 2014, new and used cars, trucks, machinery, boats and parts imported from the United States must be treated before being shipped to New Zealand.

For details about the new treatment requirements, read the import health standard.

The treatment requirements were introduced after several infestations of brown marmorated stink bugs were found in vehicle and part consignments from the United States.

MPI has re-approved the offshore treatment schedule for sulfuryl fluoride to treat vehicles and machinery for the management of the brown marmorated stink bug. Details of the treatment are in a new CTO direction dated 20 February 2017. Other treatment methods are in the IHS.

MPI approved new post-treatment periods for the offshore treatment for vehicles from the United States. Details of the changes are in a new CTO direction dated 22 December 2016 and are included in the grey box on the title page of the IHS.

  • For the west coast of the USA (Washington, Oregon and California states) a maximum post-treatment storage period prior to loading of 144 hours is allowed
  • Post-treatment periods prior to loading for heat, methyl bromide and sulfuryl fluoride of 96hrs is allowed for the rest of the USA.
