KiwiSaver: Why Many New Zealanders Are in the Wrong Fund

KiwiSaver is one of the most powerful retirement savings tools available to New Zealanders — and yet, for many members, it is quietly underperforming. Not because of poor market returns, but because the fund they are in simply does not match their circumstances. Most New Zealanders are in a KiwiSaver fund that does not align with their age, goals, or risk profile, and the cost of that mismatch compounds year after year.

The Default Fund Problem

Many KiwiSaver members were auto-enrolled into a default fund when they started — and never reviewed it since. Default funds are designed to be a reasonable starting point for the average member, but they are built for the masses, not for you. A default conservative or balanced fund may be appropriate for some, but for a younger member with decades until retirement, it can mean missing out on the growth that a more growth-oriented fund would provide.

The problem is that most members never revisit their fund choice. Life changes — income changes, goals shift, retirement timelines shorten — but the fund stays the same. Over twenty or thirty years, the gap between the right fund and the wrong fund can translate to tens of thousands of dollars in lost retirement savings.

The Risk Profile Mismatch

KiwiSaver funds are typically categorised by risk profile: conservative, balanced, growth, and aggressive. The right choice depends on your age, your financial goals, and your tolerance for short-term volatility. A member in their twenties with decades until they need the money can typically afford more growth-oriented exposure, because they have time to ride out market fluctuations. A member approaching retirement may need to shift toward a more conservative stance to protect what they have accumulated.

But many members are in a fund that does not match their stage of life. Some younger members sit in conservative funds, sacrificing long-term growth for stability they do not need. Others approaching retirement remain heavily in growth funds, exposed to market downturns at exactly the wrong time. Neither is optimal — and both are avoidable with a proper review.

The Limitations of Off-the-Shelf Funds

Even when members are in the right risk category, most bank and provider KiwiSaver funds are pre-built, mass-market products with limited investment choices. They offer no direct share exposure, no personalisation, and no tax optimisation. You are fitted into a pre-made box rather than having a portfolio built around you.

A truly tailored KiwiSaver portfolio — one that includes ETFs, direct stocks, and managed funds selected for your specific circumstances — can offer greater diversification, better tax efficiency, and alignment with your broader wealth strategy. This is a significant step beyond the standard off-the-shelf fund, and it is an option many members do not realise exists.

The Contribution Question

Being in the right fund is only part of the equation. Many members are also contributing at the wrong rate. The government contribution — a matching contribution up to a cap each year — is effectively free money, yet many members do not contribute enough to claim the full amount. Employer matching is another area where a small increase in your contribution rate can yield a meaningful boost over time.

Without a plan for contribution rates, employer matching, and government contributions, you may be leaving money on the table — year after year, for decades.

KiwiSaver in Context

Perhaps the most common issue is that KiwiSaver is treated in isolation. It sits in its own account, managed separately from your other investments, with no connection to your broader retirement income plan. But KiwiSaver is not a standalone product — it is one piece of your overall wealth picture. How it is invested, when you draw on it, and how it integrates with your other assets all matter for your retirement outcome.

We provide independent guidance on contribution strategy, integrate your KiwiSaver with your broader investment portfolio and retirement plan, and use PIE fund selection and FIF-aware structuring to maximise the return you keep. Because we have no proprietary products and no institutional allegiances, every recommendation is objective and in your best interest.
