Three men have been arrested as part of an police operation that netted more than $1 million of MDMA.
Detective Inspector Darrin Thomson, of the National Organised Crime Group (NOCG), said on Monday the police investigation resulted in several search warrants across Christchurch on May 22.
Three men had been arrested, and more than 4700 grams of MDMA, a Class B controlled drug, seized by police.
The men, aged between 31 and 36, face charges of importing MDMA.
They are due to reappear in the Christchurch District Court on June 13.
