"People seem to be remaining detached from their retirement savings and the steps they could take to help them achieve their goals," Body said.
The recent survey was the first time the ANZ had asked people about their balances.
The survey also revealed a shift in how much people expected to live off in retirement with a scaling back in expectations.
Previously 43 per cent said they wanted to have $500 a week to live off on top of New Zealand Superannuation.
That dropped to 26 per cent in the latest survey while the number choosing to have up to $300 in additional income increased from 36 per cent to 53 per cent.
"The impact of opening their annual statement recently and seeing how much they have in their KiwiSaver account, has probably made some people pause for thought around how much they realistically expect to save by the time they reach 65."
The survey was undertaken in May and June and questioned 1245 people in the 15 to 64 year old age bracket.
More than two million people are signed up to KiwiSaver.
