Fiji's Health Secretary, Dr James Fong, said New Zealand and Australia had closed their borders to PNG.
Currently, the only flight into Fiji is through Indonesian airline Garuda or by chartered flights, said Fong.
"Garuda-Indonesia is familiar with our stand and requirements for airlines entering Fiji airspace," he said.
"Through this understanding, Garuda-Indonesia did not pick any passengers from PNG last week, when it called into Fiji."
Earlier, the government urged Fijians living in PNG to return home if they could.#####
