New Zealand warns shipping of iceberg armada

New Zealand warns shipping of iceberg armada    New Zealand authorities have warned of a flotilla of about 100 icebergs drifting towards international shipping lanes after a sighting 250 kilometers south of the mainland, according to various news reports.
   The Royal New Zealand Air Force made the sighting late Friday and reported the biggest iceberg to be more than 1.5 miles long, a mile wide and about 400 feet high above water. It is the closest an iceberg has been seen to the New Zealand mainland for more than 70 years.
   It is thought that the icebergs could last another week as they journey to the country's East Coast.
