Papua New Guinea Catholic Church leaders say wantokism or tribalism is a form of corruption and the people of the country have got to help solve it.
Following a meeting of the Church's Assembly, the Catholic Bishops have called for their parishioners and all the people of PNG to become more active in the country's social and political life.
Bishop Douglas Young says tribalism is one of the greatest threats to good governance and if PNG could find ways to end it, it would have something to offer the whole world.
"That if we commit ourselves and don't give up and work with hope that there are enough good people around and enough strength within traditional culture to overcome this in a positive way, then we can do a lot for Papua New Guinea. I think we could offer some good ideas to the Pacific and possibly the rest of the world as well."
