PNG Ports Corporation Ltd (PNGPCL) is the successor company to PNG Harbours Board. The Company was incorporated under the Companies Act 1997 on the 19 of June 2002 as PNG Harbours Ltd and later changed its name to PNG Ports Corporation Ltd on the 7 of March 2006. PNGPCL's transition from PNG Harbours Board, a statutory corporation to a private company under the Company's Act 1997 was made possible by the amendment to the Harbours Board Act Chapter 240. The amended Act known as the Harbours (Amendment) Act Chapter 240 substancially changed the Harbours Board Act Chapter 240 to facilitate the transition of the new entity and the Act is now known as the Harbours Act Chapter 240 (Consolidated to No 15 of 2002).
The Company evolved from Papua New Guinea Harbours Board (1963-1969), Papua New Guinea Harbours Board (1970-2002) and PNG Harbours Limited (2002-2006).
