Three people have been charged with importing illicit drugs after police intercepted a courier parcel from Thailand containing 2kg of liquid methamphetamine.
Operation Torpedo was a joint investigation involving police and Customs.
It began when Customs officers intercepted the courier package which had been sent to an address in Wellington in March.
A further package containing 1kg of methamphetamine was intercepted in late April.
In total, 3kg of methamphetamine, amounting to more than 60,000 doses, was intercepted.
