Default and conservative KiwiSaver funds with low exposure to shares and property have been the best performers for the quarter ended September 30, and the past year, according to Mercer's KiwiSaver Survey.
Mercer, an international investment consultancy, said global volatility continued to affect KiwiSaver fund returns.
While KiwiSaver diversified funds largely produced negative results for the quarter - with a median return of minus 3.7 per cent - the majority of default funds managed to stay positive with a median return of 0.2 per cent, Mercer, an international investment consultancy, said.
KiwiSaver default providers have a contract with the Government that requires them to meet additional reporting requirements.
The more aggressive growth funds posted a median return of minus 7.1 per cent for the period, Mercer said.
