"We estimate the methamphetamine intercepted during Operation Georgie would have a street value of over $22 million.
"In 2006 police and Customs intercepted 95kg of methamphetamine during a joint operation at Auckland Airport. This is our biggest border seizure since then."
Customs investigations manager Maurice O'Brien said: "These criminals took a big risk and went to a lot of effort to try and smuggle the drugs undetected, but Customs officers and systems are alert to such shipments.
"I'm pleased that a very large quantity of harmful drugs will not be for sale on our streets these holidays, and the criminal syndicate will have an unhappy Christmas."
Two Taiwanese nationals have been arrested since the drugs were intercepted and charged with importing methamphetamine and possession of methamphetamine for supply.
They have been remanded in custody and are due to reappear in Manukau District Court in April.
