"The skipper was standing on the stern of his vessel waving his red jacket," he said.
The SV Albatross, which has suffered a mechanical failure, was buffeted by southwesterly swells of up to 3.5m and 20-knot winds, Walshe said.
"The Orion crew were able to establish communications with the skipper and he told them that he was safe and well but would like to evacuate from his sailboat."
The Orion crew contacted cargo ship MV Olga, which was 176km south-southeast of the stricken vessel, to help rescue the sailor. The cargo ship was expected to reach SV Albatross' location by mid-afternoon.
The sailor left Opua in the Bay of Islands on May 14 for the 14,000km journey to Papeete, the capital of French Polynesia, the RSCCNZ said.
Today's search in the South Pacific comes as the Defence Force continues to help search for a missing tramper in the Tararua Range.
Sergeant Tony Matheson from New Zealand Police said an RNZAF NH90 helicopter would fly up to 50 searchers from police and New Zealand Land Search and Rescue to the Tararua Ranges this morning to continue to look for a 49-year-old man who failed to return from a five-day tramping trip on Saturday afternoon.
