Papua New Guinea's Electoral Commissioner Andrew Trawen has announced that writs for the 111 National Parliament seats have to be returned to him by next Wednesday July 25.
Mr Trawen says this deadline allows him enough time to peruse and determine the number of seats aggregated by all parties in order to prepare his formal advice to the Governor General as to who should be invited to form government.
The Electoral Commission's scheduled date for the formal return of writs to the Governor-General is July 27.
Following this, as required by law, the political party with the largest number of MPs is officially invited by the Governor General to form government.
Mr Trawen called on all winning candidates to take heed of the legal requirements relating to return of Writs and to complete the procedure on time, saying to date only one returning officer had rerun the writ for an electorate where counting has completed.
