PNG's National Research Institute says it's concerned that the government is running out of time to properly amend the boundaries of electorates to facilitate two newly created provinces before the 2012 elections.
After the creation last year of two new provinces, Hela and Jiwaka, the constitution has to be changed by July to allow for a review of the boundaries.
However the government would need to gain an absolute majority of support in parliament where politicians blocked all proposed boundary changes since when independence was gained in 1975.
The Institute's senior researcher, Dr Ray Anere, says a lot of different electorates need to come on board first.
"In other words there is quite a lot of work in determining those electorate boundaries and district and local government boundaries. And the Electoral Boundaries Commission would need about a year to determine those respective boundaries."
