Papua New Guinea's acting deputy commissioner of Police and Chief of Operations, Tony Wagambie, has appealed to members of the police not to carry out their threat to stop work at lunch time.
Mr Wagambie says police have a sworn duty to uphold law and order and protect life and property and must continue to do so.
This comes as the police association threatens action amid a demand to re-instate Tom Kulunga as acting police commissioner.
Reports say Mr Kulunga is among several top officials to be suspended over the Julian Moti affair, but the moves against them have not been confirmed.
Mr Moti is an Australian citizen who escaped from PNG to Solomon Islands on a PNG military plane while Australia sought his arrest on a child sex charge.
