The hard decision was made to euthanize the remaining whales to put an end to their suffering.
Across a period of several days a year ago, more than 650 pilot whales beached themselves on a thin strip of land projecting off New Zealand's South Island.
Making this the fourth stranding found in Newzealand this weekend, whales have been beaching themselves a lot, authorities say, reminding that last week killer whales had to be transported to other locations to save their lives and others had to be killed, said a marine conservation group member.
"They were not in great condition", Parks Victoria incident controller Michael Turner said. Two whales later died there.
He said the remaining whales were swimming about 400 meters (437 yards) from the shoreline on Tuesday afternoon and would continue to be monitored until they swam into deeper water, their natural habitat.More news: Coldplay Releases New Music Under Different Name

A humpback whale and 27 pilot whales have stranded themselves on a remote beach in a Victorian national park.
Since the beach is isolated, it's unclear how long the creatures had been stranded before they were discovered.
"The beach is regularly used by locals and visitors so by removing the whales the beach can be enjoyed again". "It was useless - they were so big and heavy and the realization we could do nothing to save them was the worst feeling I've ever experienced".
Half of them were dead, the other was impossible to save, in this connection employees of the Department of conservation of New Zealand made the decision to euthanize them.
"Walkers on this remote section of the Wilderness Coast will also be advised not to enter the water due to the increased likelihood of sharks in the area attracted by the dead whales", an environment department statement also reads. Scientists believe strandings can be caused by a number of factors, such as the whales trying to escape predators, falling ill, or navigating incorrectly.
