Volcanic ash halts New Zealand flights

Chile's main volcano is still causing chaos in the southern hemisphere as ash from the eruption has travelled to the other side of the Pacific Ocean and is disrupting flights in New Zealand and Australia.

Qantas airlines has cancelled all its flights in and out of Melbourne saying it is too dangerous to fly in and out of the ash cloud.
