Many people on low incomes will need NZ Super to help them get by in retirement, the Retirement Commission says.

KiwiSaver balances have lifted but many people on low incomes will need NZ Super to fill the gaps, and help them get by in retirement, the Retirement Commission says.

It has released new data showing the average balance across age brackets and genders.

Average balances range from $3512 for those under 17 to $194,276 for those aged 86-plus. although the latter is skewed by a smaller number of investors in that age bracket.

The average balance across all members is now $41,286, up 11.3 percent from 2024. Men's average is $47,452 and women's $38,212.
