A foiled parcel bomb plot originating from Yemen has triggered changes to New Zealand Customs measures.
Two packages containing explosives were intercepted on Friday at airports in Britain and Dubai en route from Yemen to the United States, after a tip from Saudi Arabia.
New Zealand Customs says it has raised the risk assessments on all sea and air cargo from those destinations.
Trade and marine manager Paul Campbell says the elevated assessment also surrounds any cargo that could be of greater risk in the light of events.
Mr Campbell says the agency is not just focussing on where flights are originating from.
He says small amounts of cargo are flown direct to New Zealand from the Gulf.
