An estimated 31 whales have died after becoming stranded on Farewell Spit late last week.
The stranding was first reported late on Thursday night. Rangers were sent to the site, but an incoming tide and night conditions meant they were unable to remain there overnight.
When rangers arrived on Friday morning there were total of 34 whales stranded, of which five were alive.
Department of Conservation rangers and Project Jonah medics successfully refloated five pilot whales with the 11am high tide on Friday.
However, two pilot whales were found deceased along Farewell Spit on Saturday and this comes after the other three were euthanised by the Department of Conservation.
Euthanised is only done by DOC for the welfare of the animal, when it is in poor condition and was not going to survive.
