What you’re seeing: your LINZ parcel boundary on satellite imagery, priced by property area. InSAR reads buildings and hard surfaces best - it’s less reliable on bush, water and very fast movement. See “Where LandSure works best” below.

Each dot is a place the satellite can measure, usually a roof or paving. A dot is not a warning. A record may show movement, or very little.

Why people check the ground
Satellite readings for the hard surfaces on and around the property, going back up to ten years.
Keep it for a property you own, or use it to decide what to ask about one you are looking at.
Share it with your building inspector or geotechnical engineer, who can check the site in person.
The report says what was measured, what was not, and what satellite readings cannot tell you.
Please read before you buy. LandSure is not a geotechnical engineer, and this report is not a geotechnical assessment, certification or a professional opinion. It is a record of how measured surfaces have moved, made from satellite data. It is meant to be used alongside your local geotechnical engineer, who knows your area and the differences in the land. InSAR does not work equally well in all land types, so please check that this product is right for you before purchasing.
Common questions about the free check
Is the free property check really free?
Yes. Enter an address to see the LINZ property boundary, the property's area, the report price and where the satellite has measurement points on and around it. You only pay if you buy the report.
How is the report price worked out?
By the property's legal area from the LINZ record of title: $345 up to 500 m², $575 for 501 to 1,000 m², and above 1,000 m² $575 plus $0.46 for each square metre over 1,000, all NZD including GST. Online orders go up to $2,500; larger areas are quoted by our team.
What do the dots on the map show?
A dot does not mean a problem. Each dot is a place where the satellite gets a steady signal, on the property and up to 100 m around it. SatSense keeps a record for each one. A record may show movement, or very little: the free check shows only where the points are, and the report gives the full record for every point on the property.
Why are there no points on my lawn or garden?
Radar only measures hard, stable surfaces such as roofs, paving and rock. Lawns, gardens, paddocks and bush usually have no readings. No point there is not the same as no movement.
