A large number of pilot whales refloated after beaching at Farewell Spit in Golden Bay are in danger once again.
The 40 whales were refloated just before noon by Department of Conservation (DOC) staff and volunteers after stranding themselves this morning.
"Thirty of the whales had begun swimming in deeper water towards Separation Point, at the top of Abel Tasman National Park'', however 10 of them remained close to the coastline.
"Early this afternoon all the whales turned towards Farewell Spit and began stranding about 3km up from the base of the Spit,'' DOC said.
Initially, 53 whales were found stranded this morning, however 13 died before they were able to be refloated.
