As New Zealand is right in the middle of two tectonic plates earthquakes are also common, I personally have experienced at least a dozen, usually about one every 2 years. Like Los Angeles, a big one is predicted for Wellington.
Lakes and rivers are perhaps the most striking feature of the New Zealand landscape. It seems like every where you look there is a river or lake. This is a result of the high rainfall that New Zealand experiences, particually in the west coast of the South Island.
