A stranded orca has been saved by soldiers and charity workers in New Zealand.

The 'killer whale' was stuck on Marfells Beach for over 24 hours after the first rescue attempt failed.

25 soldiers from New Zealand, American, Canadian and Australian plus volunteers returned the second day determined to set the young marine animal nicknamed ‘Lucy’ free.

The operation involved digging a trench in the sand, about 1m deep and 20m long. Armed with pontoons and an airbag they managed to drag the 1.5 tonne Orca back into the water.

With the help of the high tide, the 'Lucy' was back where she belongs by 1.30pm.
