Reading this briefing
Tier A — Confirmed: a regulator or court has acted or published. Tier B — Reported: the organisation’s own disclosure or credible media, awaiting official confirmation. “People affected” is what the organisation or regulator disclosed; “Not disclosed” means no official figure exists, and we don’t estimate. Totals add disclosed figures only and may overlap.
breach.co.nz is an index of public record, not an investigator. Every record is drawn from regulator releases, court material or the organisation’s own disclosure, and links to its source online. Figures reflect what those sources reported; matters before the courts are allegations not yet determined. Check the live record for the latest — this print-out is a snapshot.
