The survey of over 1,000 people found 40 per cent of these people who want to work would continue in full-time work while 60 per cent would work part-time.
The ideal scenario for the majority of respondents was to continue working in their current job but with reduced hours.
The reasons were to keep active, because they enjoy it and to boost their retirement income.
Some 24 per cent said they did not feel ready to stop working while 21 per cent did not want to be at home all the time.

Those who said they were going to retire said they planned to more physical activity and socialise more.
Stan Russell, Prudential's retirement income expert, said: "In the past, people went from being in full-time employment one day to being retired the next. Retirement is much less of an event these days due to flexible working behaviour.
"Retiring at 60 or 65 years old is no longer a financial reality for many people and the phased changes to State Pension Age acknowledge this is the case. Some people do not want to retire at all while others are happy to retire as early as possible."
The State Pension age is set at 65 years old for men and 60 years old for women.
