Terms & Methodology

Last updated: 25 April 2026

By using crimecheck.nz(“the site”) you agree to these terms. The site is a free, non-commercial information tool operated by John Gregoriadis (“the operator”) and is not affiliated with, endorsed by, or operated by NZ Police, Stats NZ, or any government agency.

Data sources & license

The crime statistics shown on this site are derived from two public datasets, both released under the New Zealand Government Open Access and Licensing framework (NZGOAL v2) and reused under the Creative Commons Attribution 4.0 International (CC BY 4.0) license:

The derived statistics on this site are made available under the same CC BY 4.0 license. If you reuse them, please attribute “CrimeCheck NZ” with a link back to crimecheck.nz, and continue to attribute the upstream NZ Police and Stats NZ datasets as required by their licenses.

Methodology

Police victimisation records are joined to Stats NZ Area Units via meshblock centroids (~99% join rate). For each Area Unit we compute totals, monthly distributions, hourly and daily patterns, and location-type breakdowns over the 48-month window.

The vs national averagefigure is the Area Unit’s monthly average divided by the national average per Area Unit. The colour shown on each suburb page is a tint based on this multiplier — it is a simple comparative indicator, not an official designation, risk score, or assessment of any place, person, or business.

The year-on-year change compares the most recent 12 months against the prior 12 months.

The indicative social cost figure (where shown) is computed by multiplying offence counts by NZ Treasury / NZIER published per-offence average cost estimates. These per-offence estimates were designed for national-level rollups and not for sub-national attribution; the figure is therefore an indicative comparison index, not an actual financial loss for the area. It should not be used for property valuation, insurance underwriting, or commercial decisions.

Privacy & suppression

CrimeCheck only displays aggregated data — there are no individual records, victims, or offenders shown anywhere on the site. To further reduce any re-identification risk in small or low-incidence areas, any single bucket with a count below 6 is displayed as <6 rather than the exact number. Location-type breakdowns are omitted entirely for Area Units with fewer than 50 reports over the 48-month window.

See the privacy notice for how the site handles personal information of subscribers to the alerts service.

Right of reply

If you operate a business or own property in an Area Unit and believe a figure or comparison shown on this site is materially misleading or out of date, please contact the operator at hello@crimecheck.nz. We will review and, where appropriate, correct, annotate, or remove the relevant content within a reasonable timeframe.

No warranty

The site is provided “as is”. While we make reasonable effort to keep statistics accurate and up to date, we do not warrant the data’s correctness, completeness, or fitness for any particular purpose. Crime statistics describe the past and are not a prediction of future events. Use of the site is at your own risk.

Governing law & jurisdiction

These terms are governed by the laws of New Zealand. The parties submit to the exclusive jurisdiction of the courts of New Zealand for any dispute arising out of or in connection with these terms.

Severability

If any provision of these terms is held to be invalid or unenforceable by a court of competent jurisdiction, that provision will be severed and the remainder will continue in full effect.
