System description
The NZ Citizenship Office extracts from its records the names, date of birth, gender and country of birth of all persons who have been granted New Zealand citizenship during the six months prior to the extraction date and sends an encrypted CD of this information to Immigration New Zealand (INZ).
The matching programme compares the citizenship information with information INZ holds relating to all overstayers. Up to seven matching cycles are used in which the matching criteria are progressively widened to allow for less exact matches to be considered. Potential matches are written to a match extract report to be verified and then accepted or rejected by INZ staff. No notices of adverse action (s.103 notices) are sent out for this programme because persons matched successfully benefit from being removed from the overstayers' register and unsuccessful matches do not give rise to any adverse action.
