Saving the lives of these stranded whales is a race against time.

Around 70 pilot whales have been found on the sand at Puponga Beach in New Zealand this week.

More than 100 volunteers worked tirelessly to get the animals floating again.

It's no mean feat to return these mammals to the sea. But only 46 survived and are now safely swimming in deeper water.
