OnePath and ASB lead the KiwiSaver pack

Morningstar's co-head of fund research, Chris Douglas, said that while KiwiSaver results for the second quarter were mixed, largely due to the high Kiwi dollar creating a headwind for offshore investments, "it's pleasing to see that many KiwiSaver funds are continuing to perform admirably over longer timeframes, especially when looking at performance from an investor's standpoint."

The survey also found that OnePath (mapping to SIL, ANZ and National Bank KiwiSaver options), Mercer and Westpac were the best performing multi-sector KiwiSaver options over the June quarter.

Looking at one and two year figures, a better indication of a fund managers performance, the survey found the Fisher Funds Growth KiwiSaver was the best performing multi-sector fund, "streaks ahead of peers over the past three years," according to Douglas.

Aon held the second and third place spots with the Aon KiwiSaver Russell and Aon KiwiSaver OnePath.
