An injured Indonesian seaman was winched from a fishing boat by the Northland Rescue Helicopter crew in a textbook operation.
The alarm was raised by the Rescue Co-ordination Centre in Wellington which then contacted the Northland-based rescue team.
Pilot Peter Davies said the fishing vessel Carmen Tere was about 314km west of Cape Reinga when the initial call for help was made on Sunday evening.
That was outside the range of the helicopter so the vessel steamed closer and about 4am yesterday the rescue crew made the 277km dash across the ocean.
"Once we get to a vessel we have a half-an-hour turn-around time so it happens very quickly," Mr Davies said.
