Manasseh Sogavare was forced to postpone the Suva leg of his tour after Cyclone Winston struck Fiji.
While in Suva, the Prime Minister will give nearly $US900,000 to assist in the recovery and rehabilitation effort.
Mr Sogavare has been touring member countries including Vanuatu, Papua New Guinea and New Caledonia.
The leaders of the Melanesian Spearhead Group are concerned at the state of the MSG secretariat and are planning a special summit to try and remedy it.
