"To be eligible for NZ Super, you need to be aged 65 or over and be a legal resident of New Zealand. You can get NZ Super even if you’re still working.
Currently you need to have lived here for 10 years since age 20. Starting in July 2024, however, this residency requirement is gradually increasing to 20 years by July 2042.
You'll need to have lived in New Zealand, the Cook Islands, Niue or Tokelau (or a combination of these) for 20 years since age 20, with 5 of those years from age 50 or older.
