Min weight is the smaller of the two weightings — if you hold both funds, that is the floor of your exposure to that position. Direct holdings only: anything either fund holds through an underlying fund or ETF is not counted, so the real overlap can only be higher. From each fund's FMA Disclose full portfolio filing.

Milford Conservative Fund
Why these two differ
The most material structural difference between these two funds is their asset allocation. The Milford Conservative Fund holds 23.37% in growth assets, classifying it as a conservative portfolio anchored in fixed income — its top holdings are all New Zealand government and local government bonds. The Booster Socially Responsible High Growth Fund sits at the opposite end of the spectrum, with 98.37% in growth assets and top positions in global equities including NVIDIA, Apple, and Microsoft, alongside Fisher & Paykel Healthcare. This divergence in construction is reflected directly in their risk indicators: Milford Conservative carries a rating of 3 out of 7, while Booster Socially Responsible High Growth carries a 5 out of 7.
The five-year return figures follow the same pattern. Booster's fund returned 6.76% per annum over five years against Milford's 2.5%, though higher historical returns in growth-oriented funds are typically accompanied by greater volatility and the possibility of larger short-term losses. Fund sizes are comparable — NZD 939 million versus NZD 873 million respectively — so neither fund presents an obvious liquidity distinction at this snapshot.
Fees differ meaningfully: Milford charges 0.85% annually, while Booster charges 1.35%. Booster's fund is a KiwiSaver scheme account fund; the Milford fund is a retail managed fund — investors should confirm which vehicle suits their circumstances. Both funds sit within the Diversified category but represent opposite ends of its risk-return spectrum.
