Papua New Guinea's Centre for Environment Law and Community Rights, or CELCOR, wants police working for logging companies to be sacked from the force.
This follows the killing of two landowners and a policeman at a forestry site in East Sepik last month.
Those deaths have sparked a parliamentary call for an inquiry into police staff working for logging companies as security.
CELCOR's Peter Bosip said police working for logging companies must no longer be tolerated and the Police Commissioner, David Manning, has to take action.

"The Police Commissioner to call all of the men out of the logging camps and wherever police are found to be conducting illegal business by working for a logging company they should be terminated," he said.
CELCOR is also advocating other steps including a moratorium on all logging, a ban on the export of round logs, and the promotion of local operators who can develop downstream timber businesses.

The NGO's fourth aim is for the country's 31 year old forestry legislation to be re-written to take account of PNG's diminishing forests - of which Mr Bosip said only half remain.
"We need a complete overhaul in the way the forest resources are governed or managed and utilised in this country,' he said.
"And we need to create a law that is reflecting on the current status of the forests, and how we can manage the remaining forest. If we don't all the forest will be gone."
