Senior Sergeant Tepias Map said this today before counting for the Moresby North-East seat resumed.
Map told candidate John Kaupa and others this morning that scrutineers must be decent and must work alongside election officials; not disrupt the process.
He said there were many disruptions by scrutineers, which have delayed counting.
He also called for scrutineers not to verbally assault and intimidate counting officials and Electoral Commission staff.
Meanwhile, the candidates are expected to identify their scrutineers before they enter the counting venue.
