The Cook Islands is seeking 41 million US dollars at the Pacific Energy Summit in Auckland to assist with green energy initiatives.
Pacific leaders and representatives from agencies such as the European Bank, the United Nations Development Programme, the Asia Development Bank and the International Renewable Energy Agency are attending, along with private investors.
The Cook Islands aims to have six islands in the group obtaining their energy through renewable means by 2015, and then all islands by 2020.
Henry Puna says the country's recently completed Renewable Energy Implementation Plan sets out the targets.
"High on the government agenda in the coming months is the question of how the state controlled generation and distribution of power may be transformed with the intervention of private sector investment in renewable energy generation and the prospects for public private partnerships."
Several outer island renewable energy systems in the Cook Islands are already funded by the Governments of Japan and New Zealand.
