Papua New Guinea's airports are set to be redeveloped in a significant deal struck with the Asian Development Bank.
The bank is investing 480 million US dollars over the next eigth years in PNG's Civil Aviation sector.
The bank's representative Allan Lee has told the Post Courier newspaper that safety and security at airports were the concerns that led to the deal.
The National Airports Commission signed a six million dollar contract with a New Zealand consultancy firm, Beca International, to redevelop the airports' infrastructure.
The deal comes after reports earlier this year in the Post Courier alleging there was scarce training for safety and rescue staff at all airports and a lack of upkeep of fire fighting and safety equipment.
