Speaking at the 11th annual PNA Ministerial meeting in Kiribati, Dr Aqorau told the ministers he was greatly honoured to have served as CEo of the PNA, and immensely proud of the achievements attained since the establishment of the PNA Office.
RNZ reports Aqorau says the PNA is now a global brand, known internationally and respected throughout the tuna industry.
He says they have been able to project the PNA to the world and demonstrate internationally that a group of Small Island Developing States can do something for themselves, without relying on donors, building a cost effective organisation able to have an impact far beyond their small size.
Ludwig Kumoru, Deputy Managing Director of Papua New Guinea's National Fisheries Authority, is expected to take over as PNA CEO from the 1st August 2016.
Dr Aqorau is to return to his Solomon Islands' home.
