Kumagai Gumi
Kumagai Gumi was contracted by NPF to build what is now known as the Deloitte Tower in Port Morseby, in 1997. The project was beset by delays and overran its initial schedule, which when coupled with the devaluing of the Kina in 1998 and 1999, reduced the profitability of the project for Kumagai Gumi and led it to register a devaluation claim against NPF.
