Is Your Home Properly Insured? Why the Cordell Calculator Matters More Than Ever
In today’s market, one of the biggest risks homeowners face isn’t a natural disaster or a major accident — it’s being underinsured without even realising it. With building costs rising year after year, many
New Zealanders are discovering too late that their home insurance cover simply isn’t enough to rebuild their property if the worst happens.
This is where the Cordell Sum Sure Calculator becomes an essential tool.
What is the Cordell Calculator?
The Cordell Calculator is an industry‑standard tool used across New Zealand to estimate the true cost of rebuilding your home, including:
Construction and labour
Materials
Professional fees
Demolition and site clearance
Compliance and council requirements
It gives you a realistic, up‑to‑date rebuild estimate — something guesswork or outdated figures can’t provide.
Why Getting Your Sum Insured Right Is So Important
Your insurance payout is based on your sum insured, not the market value of your home. If your sum insured is too low, you may face:
A shortfall in a total‑loss event
Delays in rebuilding due to funding gaps
Stressful financial decisions at the worst possible time
Underinsurance is far more common than people think, especially as building costs have increased significantly in recent years.
The Cordell Calculator Helps You Avoid Costly Surprises
Using the Cordell Calculator ensures your cover reflects current rebuild costs — not what they were when you bought your home or last reviewed your policy. It’s one of the simplest ways to protect your biggest asset. Even better, it only takes a few minutes and can save you thousands in the long run.
