Police said the two men, who are in their 40s, were arrested when they came to get a parcel containing 5.9 grams of methamphetamine.
RNZI reports the two suspects were charged with possession and importation of an illegal drug.
They will appear in the Supreme Court in two weeks.
Police spokesperson Superintendent Sala'a Moananu Sale has told reporters that inquiries have been made with American Samoa authorities on how the illegal drug got through customs checks.
