What we do not use
We do not show or use owner names, rating valuations, or any valuation-roll information. We hold no LINZ bulk personal-data (owner) datasets.
What this information is not
It is not a LIM, a title search or a hazard report. A record can be missing, out of date or wrong, and a count of titles is not a count of homes. For the official versions ask LINZ or your council, or ask your own lawyer. See the terms.
See an error?
If a figure looks wrong, the fix usually has to be made at the source, and we pick up its next release. Tell us and we will explain where to take it.
