The French Polynesian government says three major projects are being studied to invest $US120 million from next year until 2023.
The figure was given by the vice-president Teva Rohfritsch at an economics conference in Papeete.
He said the projects included a new cultural centre.
Mr Rohfritsch reiterated that the New Zealand company Kaitiaki Tagaloa has until the end of the month to prove its ability to build a $US700 million part of the Tahitian Village tourism complex.
He said he hopes it will go ahead with the Māori company, adding that others are standing by to take over the hotel construction project.
The company has secured two extensions since March after failing to meet the deadline agreed to last year.
He also said the much delayed Chinese project to build the South Pacific's biggest fish farm at Hao atoll is now set to start in August.
