The Fiji Navy says the decision follows a multi-day search operation that intensified over the last 48 hours after a missing semi-submerged fibreglass boat was recovered and confirmed to be the vessel involved.
They say the decision was made after careful consultation between search teams and a thorough review of the operation, including the large area covered, weather and sea conditions, drift analysis, survivability considerations, and all information gathered, including reported sightings and floating debris.
The Navy says the large-scale operation involved surface vessels from the Republic of Fiji Navy and Fiji Police Force Water Police, defence-chartered aircraft with Navy air crew, local air assets, and assistance from regional partners, including the Royal New Zealand Air Force.
The Navy has also acknowledged the support of local communities, maritime operators, and members of the public who provided information and assistance throughout the search effort.
It says while coordinated air and surface search operations have now been suspended, the case remains open and authorities will continue to assess any new information, sightings, debris reports, or developments that may assist in the search.
The Navy says if credible new information emerges, search and response operations may be reactivated.

It has also thanked all agencies and partners involved in the operation, particularly Rescue Coordination Centre New Zealand and the Royal New Zealand Air Force, while extending its thoughts and prayers to the families of those still missing.
The Navy is also urging mariners to prioritise safety at sea by ensuring vessels are seaworthy, checking weather conditions, carrying communication equipment, wearing lifejackets, and sharing voyage plans before setting out.
Anyone with information related to the case is urged to contact the Fiji Rescue Coordination Centre on 1539, or report sightings or debris to the nearest Police Station, Navy, or maritime authority.
