8,000 vehicles in February were rejected after bug infestations were discovered on shipments from Japan.

Financial Times:

The Ministry for Primary Industries, the body tasked with protecting New Zealand’s biosecurity, said in February it had introduced new measure to reduce the risk of brown marmorated stink bugs from arriving in machinery and vehicles from Japan.

All vehicles will now have to undergo inspection before leaving Japan.

“The move is the result of an unprecedented spike in the number of stink bugs arriving at the border from Japan in bulk carriers,” MPI said, adding that three bulk carriers were directed to leave New Zealand “due to excessive contamination”.
