Due to restrictions in Apia, the travellers were reportedly denied entry into Samoa yesterday after they had flown from China via Hong Kong and Nadi.
Fiji's information ministry said on return to Nadi, all six were examined by a doctor and assessed as well, with no fever.
They are in quarantine to be cleared to fly.
The ministry said all six were from Fujian province in China, and none had a history of travel to Wuhan or Hubei province where the coronavirus outbreak started.
