KiwiSaver fees have fallen in the last year but so have average returns for funds with a higher proportion of share investments.
Based on an account balance of $20k the average annual fee on a growth fund has dropped by 8 per cent in the last year to $181.64, research by Canstar has shown.
Balanced funds also saw a 6 per cent drop in the average annual fee to $160.79 while conservative funds saw the smallest drop of 4 per cent to $122.49.
Providers have been under the pump to do better on fees with both the regulator - the Financial Markets Authority - and the government putting the spotlight on them.
A review of the KiwiSaver default providers, launched this year, will also take account of fees when it comes to appointing the providers for the next seven year term. The current term ends in 2021.
