AI summary
This guide explains NZ home insurance, which typically uses a sum insured model. This is the maximum rebuild cost, and homeowners are responsible for calculating it accurately to avoid being underinsured.
Your policy works alongside Natural Hazards Cover from the Natural Hazards Commission (NHC), which pays for the first portion of natural disaster damage. Your private insurer then covers the rest. It is crucial to review your sum insured amount regularly to stay protected.
