Fisher Funds has been under fire this week for charging high fees on some of the legacy funds it acquired as part of its Tower funds management buy-up.
Independent research firm MoneyHub has accused Fisher of "ripping off" customers by charging high management fees.
The 14 funds which have $289 million invested from around 20,000 people charge between 1.5 per cent and 6.83 per cent for management.
They have been closed to new investment since 2005 and progressively members have been moved out.
Fishers' chief executive Bruce McLachlan says clients aren't being "ripped off" because they are getting what they signed up for.
