Customs has seized about six million dollars worth of methamphetamine from the luggage of a tour group arriving at Auckland Airport.
Seven people, all Taiwanese, have been arrested and charged with importing a Class A controlled drug.
Two of the group have also been charged with a further two counts of drug importation relating to an incident in March.
Customs says the group was arrested last Sunday and they appeared in court on Monday and were remanded in custody.
Customs found 8.175 kilograms of methamphetamine hidden in the group's luggage.
It says a customs officer discovered the drug hidden in sealed food and beverage containers in one person's luggage.
The other members of the group were then searched, and more of the drug was found.
Customs chief executive controller Martyn Dunne says it's unusual to for people to try and bring in the finished product rather than a precursor substance.
