Research from the National Employment Savings Trust suggested that a fifth may take some or all of their pension pot as a cash payment. Some 13% said they would take some and 7% said all of it in this form.
More than a fifth appeared to be uncertain how to go about treating their retirement funds, the survey found, with 22% saying they don't know what they will do.
But the findings also suggested that the reforms have increased awareness of and interest in the issue, with 34% of all respondents saying they will think about planning for retirement sooner. This rose to 40% among younger people (22-30).
Tom McPhail, head of pensions research at Hargreaves Lansdown, said: "The new freedoms have reinvigorated interest in retirement planning. We wouldn't go so far as to say pensions are sexy now but they've certainly become more attractive."
