PNG's registrar of Political Parties, Alphonse Gelu, last week suggested that electors should vote for parties rather than individual political candidates.
He mooted the idea with a view to strengthening political parties.
Paul Barker from the Institute of National Affairs said a simple system is needed as the current one is too complicated to easily convey what individual candidates stand for.
"What Dr Gelu is really trying to achieve is a mechanism to try and bind people to parties early on in the piece, and then parties to governments once they're making a commitment before and after the election."
Mr Barker said current legislation makes it very difficult to ensure MPs stay with the parties and party platforms they were elected on.
