Police have yet to charge anyone in the matter where more than 10kg of methamphetamine was found in Nadi last month.
Assistant Commissioner of Police Crime Mesake Waqa says the investigation is still continuing.
Police had earlier said that two men aged 36 and 42 years were questioned and released.
A joint controlled operation between the Fiji Police Narcotics Bureau, Fiji Revenue and Customs Service and the New Zealand Customs had resulted in the seizure.
