PRIF is a multi-agency coordination mechanism aimed at improving the delivery of development assistance from donors and development partners to the infrastructure sector in the Pacific region. PRIF supports infrastructure development and maintenance in twelve Pacific Island Countries (PICs) through investment coordination, research and technical assistance.PRIF provides a framework for better engagement of countries and development partners to ensure more effective use of available funding and deliver better infrastructure services. Through deeper coordination, PRIF is able to help countries maximise opportunities for improvements in infrastructure service provision.

Development partners then contribute with their relative comparative advantage in the different infrastructure sectors and activities. - Improved prioritisation based on the national strategies of Pacific Island Countries and sector planning policies, leading to improved alignment of government and development partner priorities.- Better policy frameworks - ensuring that infrastructure investments are efficient, effective and affordable.- Sustainable and resilient infrastructure ensuring effective maintenance of infrastructure and appropriate design responses to natural disasters and climate change impacts;

Improved capacity of Pacific Island Countries to plan, develop, manage and maintain their infrastructure, and promoting mechanisms that enable technical specialists to exchange information on projects and pipelines, and develop research relevant to the Pacific Islands.
