KiwiSaver Returns — 31 August 2026 Update

Our KiwiSaver comparison is now updated to 31 August 2026. Returns are shown after fees and before tax, and this month the pattern flipped: the defensive end of the market gave back more ground than the growth end.

What changed this month

Biggest one-year moves since 31 July

  • Up: QuayStreet High Growth (+3.94), QuayStreet Growth (+3.18), QuayStreet Balanced (+2.69), QuayStreet Conservative (+1.88)
  • Down: Milford Aggressive (−3.00), Generate Thematic (−2.98), Kernel Global 100 (−1.39), Generate Focused Growth (−1.23)

QuayStreet moved up across its whole range, which is usually a sign of a single strong month entering the window rather than anything having changed about the funds. Movements of this size in a one-year number are ordinary and are not, on their own, a reason to switch funds.

Category by category

Conservative — median one-year return 3.90%, down about half a point on July. Conservative funds are dominated by bonds and cash, so their returns track interest rates far more closely than they track share markets. The range runs from 1.12% to 6.81%.

Moderate — median 5.15%, also down roughly half a point. Moderate funds sit between conservative and balanced, with a minority of the portfolio in shares.

Balanced — median 9.48%, down about a third of a point. This is the default territory for a lot of KiwiSaver members, and the median sits close to the all-fund median of 9.90%.

Growth — median 12.79%, essentially flat on July. Growth funds hold most of their money in shares, so the slower month at the defensive end barely touched them.

Aggressive — median 15.45%, also essentially flat, but with by far the widest spread of any category. This group holds everything from broad global share funds to single-market and geared strategies, and their results scatter accordingly.

Full table — returns to 31 August 2026, after fees and before tax.

Sorted by ten-year return. A dash means the fund does not yet have that much history. Past returns do not guarantee future returns. This is general information, not personalised financial advice.
