Almost 50% of consumers would find government compulsion to save into a private pension scheme helpful, research suggests.
According to a Friends Life survey of 2,000 people, half backed compulsion while a further 30% said they had no opinion.
Another 24% would view compulsion as another form of tax and said they would not want to pay it, Friends Life said.
The insurer said 61% of respondents revealed they are not confident in their own ability to save enough for retirement without government or employer intervention.
One in ten respondents did not know what their current pension contribution was, almost a fifth had no pension at all, and 35% saved less than £100 per month, the survey said.
Martin Palmer, head of corporate benefits marketing at Friends Life, said: "Our research showed that many consumers recognise they need some encouragement with getting into the savings habit, with nearly half saying they would see compulsory saving as positive.
"Auto-enrolment will provide a nudge to get many people saving into a pension that are not currently making any provisions for their retirement.
"However, it is important consumers remember that the levels of contribution made under auto-enrolment may not be sufficient to provide the level of income in retirement that they want, and they may want to consider making additional savings to help them reach their goal."
