The acting Papua New Guinea police commissioner, Fred Sheekiot, says he is very concerned about the impact of tribal fighting in the Nebilyer district of Western Highlands.
He has appointed the director of police operations, Tony Wagambie, to assess the situation.
Commissioner Sheekiot says the fighting is affecting the people across Western, Enga and Southern Highlands provinces.
He says Mr Wagambie's task will be to look for an immediate solution to fighting which has resulted in the deaths of many people, destruction of property and disruption of the livelihood of thousands of people.
Mr Sheekiot says a heavy police intervention at this stage would be foolish.
He says they want to open dialogue with both tribes involved in the fight to find a peaceful solution.
