Customs has made its largest ever methamphetamine seizure at the border.
Three people - two Canadians and a New Zealander - have been arrested and appeared in Auckland District Court today.
They found another 15kg of methamphetamine, a hand gun, and a large quantity of cash, the statement said.

Customs Investigations Manager Bruce Berry said: "It's a known international trend for overseas nationals to come into the country just to receive and distribute drug shipments. They use storage units or commercial premises and hire homes on Airbnb as part of their illegal activity...
"We urge storage units, commercial premises, and Airbnb operators to be alert so they don't unwittingly become involved in criminal activity."
Detective Superintendent Greg Williams said the seizure equated to "between 22 and 26 weeks' supply of national consumption, according to wastewater analysis figures".
Police said further arrests were likely.
