Two men are due in Rotorua District Court this week, on drugs and firearms charges.

This follows several search warrants issued on December 11 at addresses in Rotorua, says a police spokesperson.

The warrants were carried out as part of Operation Denim, executed by Rotorua and Bay of Plenty Organised Crime Squads over several months.

"Two firearms were located, along with MDMA and $30,000 cash.

"We would like to remind members of the community, if you see any unlawful or suspicious activity, please call Police at 111 if it’s happening now, or on 105 if it’s after the fact."
