Five divers are on their way to scour the water for crew members of a fishing vessel that went missing near Canterbury in a storm yesterday.
A boat was located on the seabed last night but three crew from the FV Jubilee, who sent out a distress call during "brutal" weather about 4.30am yesterday, have still not been found.
Canterbury police said five members of the Wellington-based police dive squad would help with the recovery phase of the operation today.
Inspector Craig McKay said a commercial fishing vessel located an "item of interest" near the FV Jubilee's last known position using sonar yesterday.
The Transport Accident Investigation Commission has since launched an inquiry into the sinking of the FV Jubilee, in order to prevent a recurrence.
