Last week, the two main suspects were charged and remanded after a raid on a house on Tahiti's peninsula where they had set up a lab to produce the banned drug.
The five were allegedly also involved in the operation by buying medicines at pharmacies to make methamphetamine.
They were reportedly given some of the drug in return.
The couple at the centre of the operation are in their mid-30s.
If convicted, they could face a prison sentence of up to 20 years.
