National-ID patterns loaded when you pass countries=["NZ"] (or "all"). Universal patterns always stay.

This is a detector, not a legal opinion

id-extract matches the shape of these numbers. A hit is not proof that the value was issued, is still valid, or that the cited statute applies to your document. Checksums, where present, only test the extra digit.
