In 2009 the Fijian military regime seized Momi Bay against the wishes of Bridgecorp receivers in an effort to stem the losses of the Fiji National Provident Fund, which was exposed to Momi Bay.
Bainimarama announced in 2012 that the fund would invest about F$150 million ($103 million) to complete the first stage of the development.
He officially launched the Momi Bay redevelopment project yesterday and welcomed Fletcher Building as a "construction partner".
A Fletcher spokesman told the Herald the company was the lead contractor on the redevelopment, which was worth F$199 million to the company.
The project involves recladding the existing structure as well as fitout and work on a lagoon.
The resort, which Bainimarama said would generate 400 jobs during construction and a further 500 when open, will be operated by global hospitality chain Marriott.
