The national drugs and vice squad, which is investigating ongoing meth suppliers and consumers in the city, were alerted to the movement of the drugs via small packages at FedEx.
Deputy commissioner of police specialist operations Donald Yamasombi said police received a tip-off and monitored the FedEx office where they apprehended a taxi driver and woman passenger.
Police then found 170g of meth in sealed small packages, packed as documents. Both were taken in by police, Yamasombi said.
"Both cooperated and took police to a housing estate in which 117kg of meth or ice was uncovered."
"The Malaysians were identified as Leong Aunfong and Tan Kheng Soon, who were found in the possession of the illicit substance."
Aunfong 42, from Malaysia's Pulai in Johor, Soon, 29, from Kuala Lumpur, Daniel Andi, 32, from Mendi, Southern Highlands, and Niaka Viri from Korobosea, Moresby South in Port Moresby have all appeared in court.
Yamasombi said that the rise of meth was a concern for me and the policing community.
"The drug is moving throughout the city and in the next five years we could be looking at an entire generation taking this drug, with it sold openly in the streets. We need support, we need proper laws and stronger penalties."
