System description
Passports staff enter information provided on application forms into the passports processing system, KIWI. This automatically conducts birth and death checks.  Marriage checks and applications that cannot be processed through KIWI because of functionality limitations are processed using the older OLEV (On-line Live Event Verification) system.

For searches of the births and marriages entries, confirmation allows application processing to proceed. Where there is doubt, cases can be referred to BDM staff for resolution. If there appears to be a match with an entry from the register of deaths, the processing of the passport application is halted and the application referred for investigation of possible fraud.

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

Annual audits of the process are conducted to give assurance that the matching programme is operated in compliance with the Privacy Act 1993.  Reporting of these statistics to give context to the audit reports was commenced in 2008/09.
