Mass wasting also known as slope movement or mass movement occurs in New Zealand which ranges from massive rock avalanches, to rock slides, rock falls and debris flows. These became very serious due to a recent case that occurred from mass wasting happened at Mount Ruapehu in 2007. A crater lake that was being blocked by the tephra dam broke, which caused a lahar to run down the mountain. An abundance of mud, rock, and water traveled down the Whangaehu River and ended up forming a lahar and in an emergency situation, all major roads in the area were shut down, which trapped thousands of people trying to pass through, but no injuries or deaths occurred. I couldn't find any information about how New Zealand warns people and prevention for mass wasting but the information provided in this weeks lessons had a landslide preparedness page which had helpful information which many countries could benefit from doing.

Volcanic Activity

New Zealand has three different types of volcanos (volcanic fields, cone volcanoes, caldera volcanoes) and the activity occurs in six areas, five in the North Island and one off shore in the Kermadec Islands. The Taupo Volcanic Zone is highly active and most of New Zealand volcanism in the the last 1.6 million years has occurred there. The active cone volcanoes in that area are Ruapehu, Tongariro/Ngauruhoe, White Island. Two of the most productive calderas in the world are Okataina and Taupo. If a life-threatening eruption occurs, a civil defence emergency will be declared and people in at-risk areas will be evacuated.
