Police officers in Otago uncovered 80 poppy plants during raids last week.
A 44-year-old man was arrested and appeared in the Queenstown District Court today after three search warrants were executed in Wānaka on Thursday.
At one address officers seized more than 80 poppy plants, which were used for opium extraction, as well as MDMA, LSD and cocaine.
An indoor cannabis growing operation with 20 plants was also found alongside dried head and plant material.
The man is facing drugs charges including possession of methamphetamine.
A spokesperson said officers would continue to target drug suppliers.
"Police will continue to target the supply of drugs in the Otago Lakes Central area as they are aware of the harm that is being done within the community.
"Anyone with information about the sale and supply of illegal substances should contact their local police by calling 105, or phone Crimestoppers anonymously on 0800 555 111."
