The Governor of Papua New Guinea's National Capital District, Powes Parkop, says Port Moresby is rapidly running out of land for development.
He has asked the Lands Minister, Benny Allan, if his department has any plans to lease customary land for expansion.
He says state land is running out and talk of land grabbing also applies to customary land.
He says all the land outside Port Moresby towards Mt Diamond has been bought and he has questioned how municipal governments can plan in such circumstances.
Meanwhile, the Northern Governor, Garry Juffa, says the issue of land grabbing in his province is becoming serious.
