As part of two-month long investigation, police have searched several Christchurch properties targeting a synthetic cannabis ring.
In a statement, police said they executed search warrants at properties in Sockburn, Papanui, Avonhead, Riccarton and Somerfield this morning.
During the searches, officers managed to locate and seize over three kilograms of synthetic cannabis and approximately $40,000 in cash.
Three people, a 50-year-old woman, and two men, a 28-year-old and 61-year-old, will appear in Christchurch District Court tomorrow charged with drug related offences including supplying controlled drugs, possession of controlled drugs for supply and participating in an organised criminal group.
Meanwhile, a 21-year-old man and a 24-year-old woman have been charged with participating in an organised criminal group and drugs related offences.
The man is due to appear in the Christchurch District Court on 9 November, and the woman on 10 November.
Detective Senior Sergeant Joel Syme said the operation was successful.
"We know synthetic cannabinoids are highly addictive and have the ability to cause significant physical and mental harm, including potential fatal seizures.
"Suppliers of synthetic cannabinoids target and sell their products to some of the most vulnerable members of our community and we believe the termination of this operation will disrupt the supply of these drugs across the district."
Police said they will continue to target criminal groups involved in the supply of synthetic drugs.
