The residence requirement, as I've said, has actually varied over time. New Zealand's first public pension was 1898, the old age pension, and it required applicants to have continuously been resident in New Zealand for 25 years immediately preceding their application. This requirement was reduced in 1936 to 20 years immediately preceding the application. It was then reduced in 1938 to 10 years for people who were in New Zealand on 15 March 1938. Now that date is specific; it's because it was to support people hit by the Great Depression. Then what happened in 1972? The requirement for applicants for the universal superannuation benefit was fixed at 20 years continuous residence and the requirement for means tested age benefit was fixed at 10 years. So we introduced a two-tier pension system. But then when national super came in in 1977, it replaced the two-tier pension system and the residence requirement went back to 10 years, and here we are today.
