The Retirement Commissioner Diane Maxwell is now calling for the superannuation age to be lifted to 67, but not for another 18 years.
Her call comes with a couple of other recommendations for change. To be eligible, she wants people to have lived in the country for 25 years, rather than the current 10 years. She's also calling for a crackdown on non-qualifying partners benefiting from those receiving super.
The commissioner says the changes are much needed because the number of people aged 65 plus will double over the next 30 years to 1.4 million and the cost of New Zealand super will triple over the next 20 years.
Ms Maxwell spoke to Paul Henry about the financial situation New Zealand is headed for.
