Booster Wealth Balanced Fund vs Foundation Series High Growth Fund
Both are Diversified funds available to NZ retail investors. Numbers below are sourced from the FMA Disclose register via Sorted Smart Investor and reflect the latest published quarterly fund updates.
Why these two differ
The most material structural difference between these two funds is their growth asset allocation. The Foundation Series High Growth Fund holds 98.31% in growth assets against a risk indicator of 5 (out of 7), while the Booster Wealth Balanced Fund holds 53.15% in growth assets at a risk indicator of 4. Both sit in the Diversified category, but they occupy meaningfully different positions on the risk-return spectrum.
Fee structures also diverge significantly. Foundation Series charges an annual fund charge of 0.37%, compared with Booster's 0.83% — a gap of 0.46 percentage points that compounds over time regardless of returns. Neither fund discloses a five-year return figure in this snapshot, so direct historical performance comparison is not possible here.
Portfolio construction reflects contrasting approaches. Foundation Series concentrates its equity exposure across three ETFs — Vanguard ESG US Stock ETF (47.53%), Harbour Sustainable NZ Shares Fund (27.79%), and Vanguard ESG INTL Stock ETF (23.55%) — giving it a highly concentrated, passively oriented, ESG-tilted structure. Booster Wealth Balanced holds a broader mix of individual equities, fixed income, and cash, with no single position above 4%, suggesting more active diversification across asset types.
Fund sizes are comparable: Booster at NZD 11.64 million and Foundation Series at NZD 9.99 million, both relatively small pools.
Readers should verify all figures, including current fees, holdings, and risk indicators, against each fund's product disclosure statement and latest quarterly fund update on FMA Disclose before relying on any of this information.
