Employers view NEST as "largely irrelevant" as most will rely on existing employee pension arrangements after 2012, according to a new study.
The report, from the Pensions Management Institute (PMI) and Standard Life, also says there is a "substantial gap" between eligibility to join workforce pension schemes and actual take-up.
Employers generally think employees should take responsibility for educating themselves about financial matters such as pension schemes, the report says.
"There is still a huge communications exercise required before people grasp the complexities and choices of DC pensions," says PMI chief executive, Vince Linnane.
"It is particularly noteworthy that 81% of those surveyed felt it was important or very important to provide good financial education to employees to allow them to make better informed decisions.
"It is interesting to note that there is a growing emphasis on encouraging long-term saving in general rather than on pension provision in particular, and this is reflected in the growth of corporate wraps offering employees access to a wide range of savings options."
