National's superannuation changes will affect 120,000 people in the first year they are fully implemented, newly-released papers show.
The papers also showed that some of the savings made by lifting the pension age will be offset by the large number of people who will still require welfare or other support.
Finance Minister Steven Joyce today released the Cabinet Paper for the Government's Super proposals, which will lift the pension age to 67 by 2040 and require migrants to live in New Zealand for 20 years, rather than 10, before they can get New Zealand Super.
It showed for the first time how many people would have to wait longer or would miss out altogether once the policy came into force in the 2040/41 year.
An estimated 113,000 people would no longer be eligible for super because of the higher age of eligibility, and around 6800 people would miss out because they no longer met the residency requirements.
