Why It's Crazy Not To Check Auckland's Growth

Auckland, New Zealand's largest city, already accounts for a third of NZ's population and its growth continues apace. In a seismically active country, this is just daft. For instance, see the maps and animations about the recent earthquake off NZ's east coast...
