A 27-year-old international traveller is due to appear in court for allegedly attempting to smuggle 9.9 kilograms of methamphetamine into New Zealand in his suitcase.

The Canadian national arrived on a flight from Vancouver on Monday, Augsut 26.

After questioning and a baggage search, Customs officers allegedly found methamphetamine concealed in several travel cube bags.

The 9.9 kilograms would have been worth up to NZ$3.5 million in street value.

In a statement, chief customs officer Ben Wells says this arrest and seizure is a great success for both Customs’ frontline officers as well as intelligence and targeting experts who work behind the scenes to identify potential drug couriers before they even get here.

“Customs screens 100 per cent of all arriving passengers using data and technology to identify individuals who may pose a high risk.

“This seizure has prevented significant harm to our communities by stopping methamphetamine from hitting our streets," says Ben.

"This is estimated to have prevented up to NZ$11 million worth of social harm and cost to New Zealand communities."

The defendant is charged with importation and possession for supply of a Class A controlled drug, as well as failure to provide passcode to access information on electronic devices.
