Reports from Port Moresby say the Papua New Guinea government may remove the electoral commissioner, Andrew Trawen.
A government spokesman says there was a flaw in his appointment and that would be rectified, adding that this wouldn't amount to a sacking.
The latest plan comes after Mr Trawen maintained that the elections were on track for June as mandated by the constitution.
But a number of MPs insist on the polls to be deferred, saying the rolls are in a poor state.
Parliament voted for a six-month deferral but after a public outcry the prime minister Peter O'Neill said it was only a non-binding motion.
However the speaker, Jeffery Nape, says the vote still stands and Mr Trawen should obey by it.
