Papua New Guinea's parliament is expected to elect a new Governor-General next month.
The term for the current Queen's representative, Sir Michael Ogio, is nearing an end.
Sir Michael, who took up the role in February 2011, was in a critical condition late last year following complications from heart surgery, but his condition has since stabilised.
It is unclear who the government is considering to nominate for the position.
However the parliamentary opposition offered to nominate the former MP and state minister Dame Carol Kidu for the role.
But Dame Carol has declined the offer, saying the timing is not right for her.
PNG has had nine vice-regals since it gained independence in 1975, all of them men.
