The declaration had been issued in February after the country was hit by Cyclone Winston.
The NDMO's director, Akapusi Tuifagalele, told FBC News that this also signalled that the Australian and New Zealand Defence Forces had completed their recovery work - seven weeks after they were deployed.
Mr Tuifagalele said the government was thankful to the forces and will continue from where they left off.
He said the Fijian military had positioned themselves on the severely damaged islands of Vanuabalavu and Koro to continue assistance.
Currently food rations are still being distributed to villages in Bua, Savusavu and Taveuni Island as their farms have not recovered from the cyclone.
