The Financial Markets Authority is warning KiwiSaver investors not to rely on a correlation between funds which charge high fees and those that give good returns.
The FMA's KiwiSaver annual report, released yesterday, has a strong focus on the level of fees charged by KiwiSaver providers.
Data in the report shows fees for "active members" (those not in default funds) have almost doubled over the last five years, from $90 per person to $173.
Over the last year, average fees rose more than 19 per cent. Some of this increase will be related to fund growth because KiwiSaver providers charge their members a percentage of the amount they have invested.
But that isn't the whole story, with fees paid rising faster than sums invested.
