Understanding your house or landlord's premium
Your property is one of a kind and your premium should reflect that. Learn what makes up a house or landlord's premium and why costs can change.
What makes up your premium?
Your premium is made up of several factors that can change from year to year—let's break down what goes into it.
You'll notice some costs are general, while others are unique to your property. This is why no two premiums are exactly the same.
Breaking down a house insurance premium
Average house premium
Base premium
This is used to cover general claims and operational costs, including our own insurance (known as reinsurance), helping protect us and our customers during significant events and catastrophes.
Risk-based premium
Using risk-based pricing, this part of your premium is based on your property's individual risk of being damaged by specific natural hazards.*
Natural Hazard Insurance (NHI) levy
This is a mandatory government levy collected by insurers and passed on to the Natural Hazards Commission Toka Tū Ake (NHC) to help rebuild or repair your home if it's damaged by specific natural hazards. Learn about the NHI levy.
Fire and Emergency New Zealand (FENZ) levy
This is another mandatory government levy. We collect it, and pass it on to FENZ to help them operate fire and emergency services across Aotearoa. Learn about the FENZ levy.
Tax (GST)
Your premium includes a 15% Goods and Services Tax (GST).
What is risk-based pricing?
When we assess your property's natural hazard risk (which informs the risk-based premium above) we look at your property individually, not anyone else's. This is a fairer way to price insurance. If we don't have data for one of the natural hazards at your address, community-level data is used instead.
Risks can change over time, so we may update premiums as new data comes in.
What else can cause premiums to change?
-
Increasingly frequent bad weather events mean more claims for insurers to cover, which can lead to higher premiums.
- Inflation and rising building costs also play a role, impacting the cost to repair or rebuild.
- Reinsurance, which helps insurers recover from large-scale disasters, can change over time due to global trends, and those costs are shared across premiums.
- Government levies (mentioned above) can occasionally go up.
It's important to understand what influences your home insurance premium so you can make informed decisions.
