My father lived in NZ until his 30s, so he fulfilled the requirement of living/(working?) in NZ for 10 years after age 20. However, it says 5 of those years must be after age 50. He is in his late 50's now, so he would, I believe, need to move back to NZ soon (for 5 continuous years) to be able to claim NZ superannuation.
However, must he work for 5 years or must he be employed? What about self-employment, or just paying tax? What if he retires relatively early and lives off savings for 5 years, would he be entitled to Superannuation at the end?
TL;DR: is the NZ superannuation time-in-NZ requirement based off of working years or just living?
