"Identity fraud is a major challenge for Immigration and is not tolerated," Mr Stuart said. "We investigate and we prosecute because the integrity of our immigration is paramount, given its importance to New Zealand and our international reputation."
Mr Stuart said residence often leads to citizenship and the issuing of a New Zealand passport.
Last year, 24 individuals who had held residence were deported.
Among them, two had their residence status revoked because they had been procured by "fraud, forgery, false or misleading representation" and five were revoked because "requirements imposed on their residence permits were not met".
Deportation orders under the Immigration Act 1987 were issued to 37 whose criminal offending made them liable for deportation, and 13 were issued with deportation liability notices under the Immigration Act 2009, which came into force in November 2009.
More than 30 have still not been deported because appeal processes have to run their course, and criminal offenders are also usually not deported until they have completed their prison sentence.
The UK was the largest source country for permanent residents last year, with 6549 or 16 per cent, followed by China 5262 (13 per cent) and India 4218 (10 per cent).
