A HELIPRO Fiji helicopter was used in the search for four men who went missing at sea on Saturday.
The four were part of a group of seven reported missing in the Lomaiviti waters by police.
Namosi Joint Venture, which is in charge of the operations of the helicopter, sent it to join the search after the navy raised the alarm.
NJV manager Ben Ackerman said NJV responded to an emergency call to aid in the search and rescue effort.
Mr Ackerman said the company would do what it could to assist in emergency relief operations in the country and it was important to use the expertise that HeliPro had brought to Fiji to assist the community in its time of need.
"Earlier this year NJV also released a contracted helicopter for emergency flood-relief operations," he said.
Helipro Fiji country manager Graeme Hedge said they had no luck in their search yesterday.
"We were out at sea for almost three hours but we did not find anyone," Mr Hedge said.
"The navy boats and also other rescue teams were out searching."
Mr Hedge said they would continue with the search today.
