An academic in Papua New Guinea with an interest in governance says the unwieldy coalitions that have made up the country's recent governments have prompted the push to extend the grace period before a vote of no-confidence.
The government has announced it wants the grace period extended from 18 to 30 months.
The prime minister, Peter O'Neill, says the votes are important as a pressure value when governments fail to perform but he says an administration also needs sufficient time to implement its policies.
The National Research Institute's Dr Henry Okole says the push for an extension is because of the uncertainty surrounding the marriages that make up the governing coalition.
"And therefore an extension of a grace period is really to try and buy more time for a government and secondly, on the practical side, to allow governments to see through the implementation of programmes."
