About this data

Where the figures come from

Every number on this site is a published official statistic, shown with its basis, sample size and lag.

The sources

Detailed quarterly bond files (Tenancy Services / MBIE), the backbone. Statistics for bonds lodged each quarter, by SA2-2019 suburb, dwelling type and bedroom count, 1993 to present. Every suburb figure, chart, trend and ranking on this site comes from these files.
Detailed monthly region & district files (same release), the Regions & districts pages. Bonds lodged each month at regional-council and city/district-council level, on their own release cadence.
Suburb boundaries, Statistics NZ’s SA2-2019 statistical areas, used to place each suburb in its district and region. Licensed CC BY 4.0.

Download the data

Every chart on the site has a Download (CSV) link beneath it, so you can take the exact figures you’re looking at, one statistical basis per file, nothing smoothed. The ranked table and each suburb, region and district export the same way. Reuse freely under CC BY 3.0 NZ; a link back is appreciated.

A downloaded CSV holds the same published statistics the pages chart; the never-mix-bases rule is enforced, so a file is always one basis. Suburb names are exact SA2-2019 labels (see the suburbs index).
