The Kiribati Government has suspended aerial searches for survivors of a ferry carrying 88 people that sank earlier this month.
Rescue Coordination Centre New Zealand (RCCNZ) acting manager Kevin Banaghan says the four search aircraft from New Zealand, Australia and the United States will return to their countries.
Kiribati vessels will continue searching.
The MV Butiraoi left Nonouti Atoll on January 18 carrying 88 passengers and crew. It sank that day.
On January 25 Kiribati authorities were advised the ferry was missing, and they then contacted Rescue Coordination Centre Nadi in Fiji. Kiribati is in Fiji's search and rescue region.
