The co-founders of one of Rotorua's Facebook community groups are clamping down on people using the site to buy and sell drugs.
Their actions come on the heels of police in Christchurch who have been contacting people in social media groups where drugs are known to be sold.
The firm no-drugs stance has been taken by Maateiwarangi Heta-Morris and the other administrators of the Rotorua Buy Sell Swap Better Facebook group page, which has more than 7000 members.
He said on other similar Facebook pages code was used to advertise drugs.
"People complain about the drugs [for sale] posts and that we don't have to block them but rules are rules," he said.
