Vunibobo died of an illness at his family home in Tamavua on Sunday.
He was Fiji’s Permanent Representative to the United Nations from 1976 to 1980 and from 2008 to 2010.
He served as Minister for Foreign Affairs, International Co-operation and Civil Aviation from 1997 to 1998.
During his second term, he represented the Fiji government led by Prime Minister Voreqe Bainimarama.
He was succeeded in February 2010 by Peter Thomson.
Former Prime Minister Sitiveni Rabuka said Vunibobo had made significant contribution to Fiji during his service.
” He was a very astute politician but he’s also more of a servant of Fiji rather than a civil servant or politician. He was more of a servant of Fiji who was guided by his concern for the nation and its people more than any political leaning or party policies. He would advice me as he saw the whole of Fiji or as he saw the majority benefiting” said Rabuka
