Papua New Guinean parliamentarians have raised the prospect of delaying the June 2012 elections, with the government questioning figures in the electoral commissioner's report.
Tabled in parliament on Friday, the report by Electoral commissioner Andrew Trawen on poll preparations says the electoral roll is about 60 per cent complete, meaning 2.4 million of PNG's four million adults are eligible voters.
However, the leader of government business, Moses Maladina, told parliament some of the figures were incomplete.
He says he has since received independent reports that this is not correct.
Mr Maladina says the electoral commissioner admitted that there were some "pockets" within the Southern, New Guinea Islands and Momase regions, which were still incomplete."
Mr Maladina also said he had received independent reports that electoral rolls for the nation's 89 open electorates had not been returned to many electorates.
Mr Trawen could not be reached for comment.
The report has been tabled in parliament but is not yet available to the public.
