Scientist Neal Young said more than 100 icebergs -- some measuring more than 200 metres (650 feet) across -- were seen in just one cluster, indicating there could be hundreds more. He said they were the remains of a massive ice floe which split from the Antarctic as sea and air temperatures rise due to global warming.
"All of these have come from a larger one that was probably 30 square kilometres (11.6 square miles) in size when it left Antarctica," Young told AFP. "It's done a long circuit around Antarctica and now the bigger parts of it are breaking up and producing smaller ones."
He said large numbers of icebergs had not floated this close to New Zealand since 2006, when a number came within 25 kilometres of the coastline -- the first such sighting since 1931….
