Mercer Responsible Trans-Tasman Shares Fund vs TAHITO Te Tai o Rehua Fund
Both are Australasian Equities 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 fee and five-year return combination. TAHITO Te Tai o Rehua Fund charges a 1.26% annual fund charge against a five-year return of 1.77% per annum, while Mercer Responsible Trans-Tasman Shares Fund charges a lower 1.06% annual fund charge but discloses a five-year return of just 0.01% per annum. Both figures are drawn from each fund's latest Quarterly Fund Update and represent past performance, which is not a reliable indicator of future performance.
Both funds sit at risk indicator 5 on the standard 1–7 scale and hold an identical growth asset allocation of 98.31%, placing them in the same structural risk band within the Australasian Equities category. Fund size is comparable — TAHITO at approximately NZD $26.9 million and Mercer at approximately NZD $31.7 million.
Portfolio construction differs meaningfully. TAHITO's top holdings are led by Meridian Energy (8.28%) and Spark New Zealand (6.68%), with a 5.66% cash position signalling some tactical liquidity. Mercer's portfolio is more concentrated in its largest holding, Fisher & Paykel Healthcare (16.29%), followed by Infratil (10.52%) and Auckland International Airport (8.80%), with no cash position visible in the top five. TAHITO's ethical investment framework draws on Māori values; Mercer's approach is described as a responsible investment screen — investors should consult each fund's SIPO for the precise methodology.
