Reviewing Your KiwiSaver Fund After the 2026 Changes
Since 1 April 2026, you're contributing more to KiwiSaver than ever before, but getting less back from the government. That shift changes the math on which fund type makes sense for you. If you haven't reviewed your KiwiSaver fund recently, now is the time.

When the money going in changes, should the fund you're in change too?
Since 1 April 2026, your minimum KiwiSaver contribution jumped from 3% to 3.5% of your gross pay, while the government contribution was halved from $521 to $260 per year. For most members, that means you're putting significantly more of your own money into KiwiSaver, but relying less on the government top-up to grow your balance.
That's not necessarily bad news. But it is a prompt to ask: is my money in the right place?
If you set up your KiwiSaver years ago and haven't touched it since, there's a decent chance you're in a default fund, a conservative fund that doesn't match your timeline, or a growth fund that no longer suits your risk tolerance. The 2026 contribution changes are a natural checkpoint to revisit your fund type and risk profile, especially now that you're contributing more out of pocket.
This article walks you through how to review your KiwiSaver fund in light of the recent changes, what factors to weigh up, and where to go for help if you're unsure.
What actually changed on 1 April 2026?
Let's recap the two main changes that took effect in April:
Minimum employee contribution increased to 3.5%. If you were contributing 3% before, you're now contributing at least 3.5% of your gross salary or wages. You can still opt for higher rates (4%, 6%, 8%, or 10%), but you can't drop below 3.5% unless you apply for a temporary contribution rate reduction (also called a savings suspension).
Government contribution halved to $260 per year. Previously, the government matched 50 cents for every dollar you contributed, up to $521 annually. That's now capped at $260. To max it out, you need to contribute at least $520 per year (down from $1,042.86).
For someone earning $70,000 a year, the minimum contribution went from $2,100 to $2,450 annually. That's an extra $350 of your own money going into KiwiSaver, but $261 less coming from the government. Net effect: you're contributing more, the government is contributing less.
If you want the full breakdown of how these changes affect your take-home pay and projections, we covered that in detail in our post on the 3.5% KiwiSaver contribution rate.
Why does a fund review matter now?
Because you're now shouldering more of the investment risk and reaping more of the reward. When the government was contributing more, a portion of your KiwiSaver growth came from funds you didn't personally put in. Now, a bigger slice of your balance is money directly from your pay.
That changes the equation in a few ways:
The impact of fund choice is amplified. If your fund's returns outperform inflation by even 1% per year over 20 years, that compounds on a larger base of your own contributions.
The cost of being in the wrong fund is higher. If you're in a conservative fund but have 15 years until retirement, the opportunity cost of lower returns applies to more of your money.
You have more control over your outcome. With less reliance on the government top-up, your contribution rate and fund choice become the two biggest levers you can pull.
To be clear: reviewing your fund doesn't automatically mean switching. For many people, their current fund is still appropriate. But it's worth actively confirming that, rather than assuming it by default.
Understanding the fund types available
Most KiwiSaver providers offer a range of fund types, typically grouped by risk and return profile. While the exact names vary by provider, the categories generally break down like this:
Conservative funds: Mostly invested in cash and bonds (fixed income). Lower volatility, lower expected long-term returns. Historically, these funds have returned around 3-5% per year over long periods.
Balanced funds: A mix of shares (equities) and bonds, often around 50/50. Moderate volatility, moderate expected returns, typically in the 5-7% range historically.
Growth funds: Heavily weighted toward shares (often 70-100%). Higher short-term volatility, higher expected long-term returns. Historical returns over 30-year periods have averaged 7-9% for diversified equity portfolios.
Aggressive or high-growth funds: Nearly 100% shares, sometimes with alternative assets. Highest volatility, highest potential long-term return.
These are broad generalisations. Actual performance varies by provider, by time period, and by how the fund is managed. Past returns don't guarantee future results, but they do give you a sense of the trade-offs involved.
The key concept: volatility is the price you pay for higher expected long-term returns. Growth funds may lose value in a bad year, but over a 10- or 20-year window, they've historically outpaced conservative funds. The question is whether you can handle the bumps along the way.
Step 1: Check which fund you're currently in
If you're not sure which fund you're in, here's how to find out:
Log in to your KiwiSaver provider's online portal or app.
Check your latest annual statement (providers send these out each year, and you can also access them online).
Call your provider's customer service line and ask.
If you've never actively chosen a fund, there's a good chance you're in a default fund. Until recently, default funds were required to be conservative. That changed in December 2021, when default funds were shifted to balanced or growth-oriented options to better suit younger savers.
If you were auto-enrolled before December 2021 and never switched, you might still be in an older conservative default fund. That's not wrong, but it might not be optimal depending on your timeline.
Step 2: Assess your risk profile and timeline
Your risk profile is a combination of your capacity for risk (how much volatility you can afford) and your tolerance for risk (how much volatility you can emotionally handle).
Here are some factors that commonly influence your risk profile:
Time until you access your KiwiSaver. The longer your timeline, the more time you have to ride out market downturns. Historically, equity markets have recovered from every major crash given enough time, but there's no guarantee that pattern will continue.
Other savings and income sources. If KiwiSaver is your only nest egg, you might lean more cautious. If you have other investments, property equity, or a partner's KiwiSaver to fall back on, you might take more risk.
How you react to seeing your balance drop. If a 20% drop in your KiwiSaver balance would cause you to panic and switch funds at the worst time, a lower-risk fund might help you stay the course.
Your plans for the money. If you're planning to use your KiwiSaver to buy a first home in three years, a conservative or balanced fund makes sense. If retirement is 20 years away, growth funds have historically been more suitable for long timelines (though this is not advice, just a historical observation).
These are the kinds of questions a licensed Financial Advice Provider would walk you through in detail. They can assess your specific situation and help you weigh these factors in a personalised way.
Step 3: Compare your current fund to the alternatives
Once you know which fund you're in and have a sense of your risk profile, the next step is to see how your current fund stacks up. Most providers publish:
Historical returns: Typically shown as 1-year, 5-year, and 10-year annualised returns. Remember, past performance is not indicative of future results, but it gives you a sense of how the fund has behaved.
Asset allocation: The percentage of the fund invested in shares, bonds, cash, and other assets. This tells you how much risk the fund is taking.
Fees: Total annual fees, expressed as a percentage of your balance. Even a 0.5% difference in fees can compound to tens of thousands of dollars over a career. You can compare fees across providers at Sorted's KiwiSaver fund finder.
You're not looking for the "best" fund (that doesn't exist in a universal sense), you're looking for the fund that aligns with your goals, timeline, and comfort level.
If you're comparing providers as well as fund types, our article on structuring retirement savings covers how KiwiSaver fits into a broader investment strategy.
Step 4: Understand the tax treatment (PIE funds)
KiwiSaver funds are structured as Portfolio Investment Entities (PIEs), which means they're taxed at your Prescribed Investor Rate (PIR), not your marginal income tax rate. Your PIR is based on your income over the previous two tax years and ranges from 10.5% to 28%.
If your PIR is set incorrectly, you could be paying more tax than necessary on your KiwiSaver returns. Check your PIR with your provider and update it if your income has changed. The IRD has a PIR calculator to help you get it right.
This won't change which fund type you choose, but it's worth checking while you're reviewing your account.
Step 5: Decide whether to switch, stay, or get advice
After reviewing your fund and comparing it to the alternatives, you'll land in one of three places:
Your current fund still makes sense. If your fund aligns with your timeline and risk tolerance, and the fees are reasonable, staying put is a perfectly valid decision. Avoid switching funds just for the sake of it.
You're confident a different fund is more appropriate. If you've done your homework and believe another fund better suits your goals, most providers let you switch online or over the phone. Switching between funds within the same provider is usually free and takes effect within a few days.
You're unsure and want personalised guidance. If you're torn between options or your situation is complex (e.g., you're close to retirement, have other investments, or are navigating a major life change), speaking with a licensed Financial Advice Provider is the safest path. They can provide tailored recommendations based on your full financial picture.

Common misconceptions about switching funds
Before you make any changes, let's clear up a few myths:
Myth: Switching funds locks in losses. Not true. When you switch between funds within your KiwiSaver provider, you're selling units in one fund and buying units in another at the current market price. If your growth fund is down 10%, switching to a conservative fund doesn't "lock in" that loss any more than staying in the growth fund does. The loss is already reflected in your balance. What matters is where you think the best future returns will come from.
Myth: You should switch to conservative funds as soon as the market drops. Historically, this has been a costly mistake. The market's best days often come shortly after its worst days. Switching to conservative after a crash means you miss the recovery. This is why having the right fund for your timeline matters, it keeps you from making emotional decisions.
Myth: Growth funds are only for young people. Age is one factor, but it's not the only one. A 55-year-old with a 15-year timeline to retirement and other income sources might still hold a significant portion in growth assets. Conversely, a 30-year-old saving for a house deposit in three years might choose a conservative fund. Timeline and goals matter more than age alone.
If you're worried about market timing or making the wrong call, that's a sign you might benefit from professional advice.
How the 2026 changes affect your long-term projection
Let's look at a quick example to see how fund choice compounds over time with the new contribution rates.
Imagine two savers, both aged 40, both earning $70,000, both contributing 3.5% (the new minimum). One is in a conservative fund averaging 4% annual returns after fees and tax. The other is in a growth fund averaging 7% annual returns after fees and tax.
After 25 years (at age 65):
Conservative fund saver: approximately $130,000 balance
Growth fund saver: approximately $180,000 balance
That $50,000 difference is the opportunity cost of being in a lower-return fund for a long timeline. Of course, the growth fund saver also had to endure more volatility along the way, and there's no guarantee those historical return averages will hold in the future.
The point isn't that everyone should be in a growth fund. It's that fund choice has a material impact on your final balance, and that impact is larger now that you're contributing more of your own money.

Final thoughts: treat this as a financial health check
The 2026 KiwiSaver changes aren't a crisis. They're a nudge to take a closer look at where your money is going and whether it's working as hard as it could be.
For some of you, this review will confirm you're in the right fund. For others, it might reveal an opportunity to adjust. Either way, the act of reviewing is valuable in itself. It keeps you engaged with your retirement savings and ensures your KiwiSaver evolves with your life, rather than sitting on autopilot for decades.
If you haven't logged into your KiwiSaver account in the last year, do it this week. Check your fund, check your fees, check your PIR. And if anything feels off or unclear, reach out to your provider or a financial adviser.
Your future self will thank you for it.
Frequently Asked Questions
Can I switch KiwiSaver funds multiple times, or is there a limit?
You can switch funds as often as you like within your current provider, and most providers don't charge a fee for switching. However, switching too frequently (especially in response to short-term market movements) can backfire if you end up selling low and buying high. It's generally better to choose a fund that suits your long-term goals and stick with it through market cycles, rather than trying to time the market.
If I switch from a growth fund to a conservative fund, do I lose the growth I've already earned?
No. Any growth your fund has earned up to the point you switch is reflected in your current balance. When you switch funds, you're selling your units in the growth fund at their current value and buying units in the conservative fund at its current value. You don't lose past gains (or lock in past losses) by switching. What changes is where your money is invested going forward and what kind of returns and volatility you can expect in the future.
Should I review my KiwiSaver fund every year, or only when big changes happen?
A good rule of thumb is to review your fund annually, ideally when you receive your annual statement. This lets you check that your fund still aligns with your goals, your timeline hasn't shifted, and your fees are competitive. You don't need to switch every year, but an annual check-in ensures you're not drifting off course. Major life events (changing jobs, buying a home, getting closer to retirement) are also good triggers for a more thorough review, ideally with input from a financial adviser.
