SuperLife Review: KiwiSaver and Investment Funds — The Everything Platform for DIY Investors

SuperLife is one of New Zealand's oldest and most established investment platforms, managing KiwiSaver and non-KiwiSaver investment accounts under one login. It offers 44 investment options spanning NZ shares, Australian shares, global shares, property, fixed interest, and cash — almost all of which invest in underlying Smartshares ETFs. The result is a modular portfolio-building approach where you choose individual fund allocations rather than picking a single diversified fund.

The NZ$12 annual administration fee for investment accounts and NZ$30 for KiwiSaver is low. The underlying fund charges range from roughly 0.30% to 0.50% depending on the fund. The combined cost is competitive but not the absolute lowest — Simplicity and Kernel are cheaper on a pure fee basis for their diversified funds.

The SuperLife Difference

What sets SuperLife apart is the control it gives you over asset allocation. You can put 30% of your balance into the NZ Top 50 Fund, 30% into the Global 100 Fund, 20% into the Australian Fund, 10% into the NZ Property Fund, and 10% into the Cash Fund. Rebalancing is free and unlimited. Changing your allocation is a few clicks.

This level of control is valuable for the DIY investor who has a specific asset allocation target and wants to manage it precisely. The downside is complexity — SuperLife's interface is functional rather than polished, and the fund range requires you to understand what you are choosing.

Performance Context

Fund charges range from about 0.25% to 0.60% depending on the fund. As with all past performance figures, returns vary over time and are not a reliable guide to future performance. The key comparison is the fee level: SuperLife's fund charges are lower than most bank KiwiSaver default funds, which typically charge 0.80% to 1.00% for comparable investment approaches.

The five-year returns on individual equity funds are more variable, reflecting the underlying markets. The NZ Top 50 Fund has been competitive with the NZX 50 index. The Global 100 Fund has tracked its international benchmark closely. The Australian Fund performance depends heavily on ASX market conditions in any given period.

The key point about SuperLife's fund charges is that they are set by the fund, not by SuperLife. Because SuperLife invests in underlying Smartshares ETFs, the fund charges are the Smartshares ETF fees. SuperLife adds only its administration fee on top. This two-layer structure means the total fee is transparent but not directly comparable to an all-in-one fund like Simplicity Growth at 0.24% which includes everything in one charge.

KiwiSaver Integration

SuperLife's KiwiSaver scheme is one of the most flexible in New Zealand. You can choose from the same 44 funds used in the investment account, or select one of the pre-mixed options if you prefer a hands-off approach. Contribution rates can be split across multiple funds — 50% into the Growth Fund, 30% into the Global 100, 20% into the Cash Fund — giving you full control over how your KiwiSaver is allocated.

The member fee is NZ$30 per year for KiwiSaver, which is standard across the industry. There is no establishment fee, no ongoing advice fee, and no exit fee. The government contribution is automatically claimed. First home withdrawal applications are handled through the normal KiwiSaver process — processing times vary but are typically within a couple of weeks.

Who Should Use SuperLife

SuperLife is a sound choice for the DIY investor who wants full control over asset allocation and values the flexibility to manage KiwiSaver and non-KiwiSaver investments from one account. For someone who wants a single diversified fund and minimal admin, Simplicity or Kernel are simpler and cheaper.

The platform handles tax efficiently — both KiwiSaver and the investment account are PIE structures, meaning the 28% PIR cap applies. The annual NZ$12 fee for investment accounts is negligible. The interface is stable and reliable, if not flashy. The investment options are comprehensive, including term deposits alongside managed funds, which gives you a single place to manage both your growth assets and your cash holdings.

How SuperLife Compares

Putting SuperLife alongside its main competitors helps clarify the choice. Against Simplicity, SuperLife offers more fund options and greater allocation control but charges slightly more in total fees. Against Kernel, SuperLife offers a broader fund range and term deposit access but has a less polished digital experience. Against InvestNow, SuperLife offers KiwiSaver integration and a more accessible interface but has a smaller wholesale fund range.

The investor who fits SuperLife best is someone who has been managing their own KiwiSaver allocation for a while, knows roughly what asset mix they want, and wants a single platform that handles KiwiSaver and non-KiwiSaver investing without paying premium fees. SuperLife is not the cheapest or the most modern, but it is one of the most capable platforms in New Zealand for the self-directed investor who wants control without complexity.
