The average lifespan of a house in New Zealand is approximately 80 years. Over time, housing materials deteriorate, and house designs become less effective in meeting modern needs. The combination of these two factors leads to homes that are less effective in meeting modern housing needs, creating substandard housing that causes health, amenity and safety issues for occupants.
