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.

Suburb names are exact SA2-2019 labels (see the suburbs index). Endpoints return the same figures the pages chart; the never-mix-bases rule is enforced server-side, so a CSV is always one basis.
