A decade ago, insurance was a formality — something sorted out in the final week before settlement, almost as an afterthought. That's no longer the case in New Zealand. As insurers reassess flood, slip, and coastal erosion exposure across the country, more buyers are discovering, sometimes too late, that a property they love comes with a policy that's expensive, restricted, or in rare cases unavailable altogether.
Insurability is now part of property due diligence, not an afterthought. Get an actual quote for the specific address before you go unconditional, not just a rough estimate.
Why Insurance Has Become a Dealbreaker, Not a Formality
Following a string of severe weather events in recent years, insurers have become far more selective about how they price risk. Two homes on the same street can now attract very different premiums depending on their exact elevation, drainage history, and proximity to a stream or coastline. For buyers, this means a mortgage approval and a LIM report are no longer enough — insurability itself has become part of the due diligence checklist.
What to Check Before You Go Unconditional
Before signing anything, it's worth getting an actual insurance quote, not just an estimate, for the specific property. Here's what matters most:
-
Flood or Overland Flow Path Notation Check council hazard layers referenced in the LIM. A flood or flow-path notation can significantly change what insurers are willing to offer.
-
Prior Weather-Related Claims Ask the vendor whether the property has had any prior insurance claims for flooding, slips, or storm damage — this history often follows the property.
-
Exclusions or Raised Excesses Some insurers will still cover a property but with specific exclusions or a much higher excess for weather events. Read the quote in detail, not just the headline premium.
-
Insurer Retreat From the Area If multiple insurers have restricted new business in a suburb or street, that's a signal worth taking seriously, even if you can still find cover today.
The Resale Risk Buyers Often Overlook
Even if you're comfortable self-insuring or accepting a higher premium, it's worth thinking about the next buyer. A property that's difficult or costly to insure is also harder to sell, and banks may be more cautious about lending against it. This is increasingly a factor in valuation, not just a personal risk decision.
Request an insurance quote as early as possible in your due diligence period, ideally alongside your builder's report and LIM. Insurance underwriting can take longer than expected, and a poor quote may be grounds to renegotiate or walk away.
A Practical Approach
Rather than treating insurance as a box to tick during the conditional period, build it into your timeline from day one. If a quote comes back with major exclusions or a premium well above comparable properties nearby, raise it with your solicitor as part of your due diligence.

Property buying in New Zealand has always required careful checks on title, structure, and council records. Increasingly, it also requires checking whether the property can be reasonably insured for years to come.
