How iQHOME Works

Choose a location, check published council hazard data, and review the results on an interactive map.

01

Select a property

Enter an address or use your current location.

02

Check council hazard data

iQHOME queries the hazard layers published for the selected city and property location.

03

Review the report

View the available hazard layers, map results, and plain-English explanations. One layer is included in the free preview.

Unlock all available layers from $1.95.

What iQHOME checks for you

Official council hazard checks across New Zealand cities, grouped by type. Expand each category to browse the checks iQHOME includes.

Use iQHOME throughout your property journey

From your first open home to long after you move in, check an address, verify hazards on site, review a property before making an offer, or check what is mapped for a home you already own.

Before open home

Check the address

Enter the property address and understand the official hazards before you visit.

On site

At the property

Use your location to instantly generate a property hazard report.

Due diligence

Before making an offer

Run one last hazard check before going unconditional or making an offer.

Existing home

Check for updates

See whether official hazard information has changed since you bought your property.

Selling

Know what buyers will see

Check your property's published hazard information before listing or selling.

Pricing

Search any supported property for free with one hazard layer included. Unlock the complete property report from just $1.95, or choose unlimited reports with a 30-Day Access Pass.

Secure payment via Stripe. Your 30-day access is protected with a one-time email verification code.

Prices in NZD. You are only charged after a full report has been generated successfully. Not a LIM, legal opinion, or survey.

Why iQHOME

Official Data

Hazard information sourced directly from published council mapping and GIS services.

Simple

Complex hazard data presented on one map with clear, plain-English explanations.

Independent

Check any supported property yourself before an open home, offer, or purchase.

Data you can trust

Each layer in a report is queried from published council GIS services, the same datasets behind GeoMaps, council hazard viewers, and LIM-related hazard mapping. Expand a city card to see the sources available today.
