System description
This programme is used to verify the eligibility of people for a New Zealand passport based on citizenship by grant or descent. It mirrors the BDM/DIA(P) Passport Eligibility Programme.

Passports staff attempt to confirm information provided on the passport application with that in the Data Aggregation Layer (DAL), as extracted from the citizenship register. Confirmation allows processing to continue. If the information cannot be confirmed, the file may be referred to Citizenship staff for resolution.

Notices of adverse action are sent when Passports staff cannot satisfactorily match the information supplied to the appropriate Citizenship record. Almost all of these are resolved by contacting the applicant for clarification.

The difference between the number of applications and the number of passports issued primarily reflects the number of applications being processed when statistics were compiled.
