KiwiSaver, explained properly (2026 guide)

Last Updated: September 2026

Most Kiwis run their KiwiSaver on autopilot. They check in once in a while, and like seeing their balance (hopefully) ticking up.

But, could you be growing your wealth (and your KiwiSaver balance) faster?

This guide covers the three decisions that matter when it comes to building your balance. You’ll also learn the flaws around KiwiSaver, including the ones nobody puts in the brochure.

By the end, you'll know whether KiwiSaver could be right for you, and how to make the most of it.

What is KiwiSaver?

KiwiSaver launched in 2007 to help New Zealanders save more for retirement. The deal was simple. Three people put money into your fund:

• You

• Your employer

• The government

Under the current rules, the default rate you contribute is 3.5% of your pay. Your employer matches it, and the government chips in up to $260.72 a year.

Here's how it works if you earn $100,000 a year. You put in $3,500 a year.

Your employer adds another $3,500. But, that gets taxed before it lands in your account. At this salary, tax takes 33%, so about $2,345 reaches your fund.

Add the government's $260.72.

So your $3,500 contribution becomes roughly $6,106 a year.

Is KiwiSaver worth it?

KiwiSaver is worth it for most people. That’s why there are 3.4 million KiwiSaver members in New Zealand.

The reason many New Zealanders sign-up for KiwiSaver is that it has benefits you can't easily replicate anywhere else.

The first is that your employer matches your contributions. So if you contribute 3.5% of your salary to KiwiSaver, your employer often will too. Then you have the government’s contribution on top.

The other major benefit is that KiwiSaver funds are locked in until you turn 65. So even if you’re tempted to spend your KiwiSaver, you typically can’t. There are only very limited situations where you could withdraw that money.

That is also why KiwiSaver is the wrong home for some savings goals. You can’t use it as your emergency fund, because getting money out early is close to impossible. That’s where you might use a savings account instead.

And not everyone gets access to the employer contributions. If you are self-employed, a contractor, or a business owner, those employer contributions come out of your own pocket.

This is why some people who are self-employed will contribute just enough to get the government contribution. Then they’ll invest in other funds where they can withdraw their money at any time. 

What KiwiSaver fund type should you be in?

The type of fund you choose has one of the biggest impacts on how much money you’ll have at retirement.

These funds are often called things like: balanced, growth, aggressive and conservative.

Every fund type has trade-offs:

• Growth funds hold more shares, so they aim for higher returns and deliver rougher years along the way.

• Conservative funds hold more bonds and cash, so the ride is smoother. But over the long term they also tend to make less money.

Neither fund type is wrong. They're built for different roads.

So how do you work out which fund is right? There are 3 main questions you can ask yourself:

Question #1 – When do you need this money, and what for?

Generally, if an investor needs the money sooner, they invest in a lower-risk fund. This generally gives a lower return. But, there is less risk that their investment suddenly drops in value.

If that money isn’t needed for a long time, then they typically invest in a higher-risk fund. This typically gives a higher return. And they are prepared for some bumps in the road.

Think of your fund like your driving speed.

If you’re driving from Auckland to Wellington, you don’t stay in second gear (at a slow speed). You have hours of open road. So crawling along wastes time.

But, in a residential street, driving 100km/h is a mistake. Because in that case, there's no room to recover if something jumps out unexpectedly.

So if you have decades until you need the money, a growth fund may suit you better. If you need the money soon, a conservative fund could be the right fit.

Just remember that you don’t have to take out all your money at retirement. Even when you turn 65, some of your money might still be invested until your late 80s. After all, you’re probably not going to spend all your KiwiSaver in one go.

So it’s worth asking: “When will I need the money?” rather than “When will I retire?”

Question #2 – What did you do in 2020?

Asset values fell sharply in early 2020. That’s when the world was heading into Covid-19 lockdowns and the markets were uncertain.

When that happened, did you switch to a lower-risk fund? Be honest with yourself here, because if you switched under pressure once, you'll likely do it again.

You're typically better off holding a fund you can stick with than the "right" fund you'll abandon in the next storm.

That March 2020 story plays out the same way every cycle. Someone moves to a lower-risk fund after the fall, which locks in the loss. Then they buy back in after the recovery, at higher prices. The fall was survivable. The switching made it permanent.

Question #3 – What other investments do you have?

Investors generally understand investment risk better if they have experienced it before. 

That’s why someone with an investment property, a business and $200,000 in shares is often more willing (and able) to handle investment risk than someone whose KiwiSaver is their only investment.

That doesn’t automatically mean that if you have less money you should take less risk. But if you have experienced the ups and downs of investing, you’re generally better able to handle it psychologically in the future.

What do KiwiSaver fees cost you?

When you invest in a KiwiSaver fund, the fund manager will take a percentage fee.

For instance if you have $100,000 invested and the fund manager charges 0.75%, then they will charge you $750 a year.

So what’s a reasonable fee to pay?

KiwiSaver fund fees generally range from 0.2% – 1.5%. And generally, the more growth assets (like shares) in the fund, the higher the fee. 

That’s why cash and defensive funds typically have lower fees than balanced funds. And balanced funds often have lower fees than growth and aggressive funds. 

That’s because it often costs the fund manager more money to manage shares and other growth assets compared to cash and short-term deposits.

A fee over 1% is too much for a fund that primarily invests in index funds. You can get that cheaply at another provider. 

But sometimes a higher fee is worth paying. The question is what you get for it.

Some funds charge more because a manager is genuinely doing something you can't copy yourself. That could be picking individual companies or investing in assets you can't buy through a cheap index fund. 

And some fees include financial advice, so you're paying for a fund and a person who checks it still fits your life. 

Though, there are two traps to watch out for:

The first is performance fees. Some managers charge a base fee plus a slice of the gains in a good year. 

Sounds fair, until you notice they share your wins but never your losses. 

The second trap catches small balances. Many funds charge a flat membership fee on top of the percentage. This stings if you don’t have much in your KiwiSaver. 

A $36 membership fee on a $5,000 balance eats 0.72% before the percentage fee even starts. The same $36 on $100,000 is relatively small.

Here is what most people get wrong about KiwiSaver

There are three major misconceptions people have about KiwiSaver:

#1 KiwiSaver is a savings account

From the outside, KiwiSaver looks like a savings account. But, under the hood it's really an investment scheme. 

That means that most of the time your money is being used to buy units in a fund. That fund might hold shares, bonds, cash and other investments on your behalf.

#2 KiwiSaver is the only thing you need for a comfortable retirement

While some people treat KiwiSaver as their whole retirement plan, it was only ever designed to be one part. The numbers back this up. The average balance across all members sits around $37,000. Even for people closer to retirement, aged 61 to 65 it's about $69,000. That’s according to MoneyHub.

That on its own isn’t likely to be enough to live on. That’s why many investors also rely on NZ Super and other investments outside of KiwiSaver.

#3 The current KiwiSaver rules won’t change

The government’s KiwiSaver settings can change, and they do. 

In the past, the government would contribute over $500 a year into your account. That’s if you contributed enough yourself. 

But from July 2025, the government halved its maximum to $260.72 a year. And if you earn over $180,000 you now get no government contribution at all. 

In addition, the age that you can withdraw your KiwiSaver is tied to NZ Super’s age of eligibility. Let’s say the government increases the age of eligibility for NZ Super to 67. That means that your KiwiSaver won’t be available until 67 too. That’s according to the current KiwiSaver Act 2006.

What are KiwiSaver's real design flaws?

KiwiSaver is a worthwhile scheme. That’s why 3.4 million Kiwis are in it. 

But at Frank Wealth I advise people on their KiwiSaver every week. From that seat, you see the cracks. So if the government asked me what to fix, here are the three things I’d tell them:

It doesn't make Kiwis save enough. The contribution rates sound reasonable, but run the numbers and they fall short. 

The default KiwiSaver contribution rate is set to rise to 4% from 2028. On a $100,000 salary that’s $4,000 a year. But even then, many people won't reach a comfortable retirement on KiwiSaver alone. 

The scheme was built to solve a problem, then the dial was set too low to solve it.

The employer match isn't always real. Some companies pay "total remuneration." That means your employer's KiwiSaver contribution comes out of your own package rather than on top of it. 

That’s why some New Zealanders skip KiwiSaver and take that money as salary instead. 

If that's your contract, one of KiwiSaver's biggest selling points doesn't apply to you.

You get access at 65, but no guidance on what happens next. The scheme is good at getting you to retirement. 

Then you get access to a lot of money straight away. There isn’t a lot of guidance on how fast to spend it, how to invest it, or how to make it last 25 more years. 

What should you do with KiwiSaver at 65?

Here's what happens for too many Kiwis. The 65th birthday arrives, the balance unlocks, and it feels like the finish line. 

So they withdraw the lot and park it in the bank "just while I think about it." 

Two years later it's still sitting there, earning less than inflation while the thinking never quite happens. 

A similar mistake others make is moving all their money into a conservative fund years too early. They think that retirement is the finish line and now that they need access to some of their money, all of it should be in a low-risk low-return fund. 

But remember that a 65-year-old might still want their money to last until 90 years old. So at least some of their money has 25 years of investing ahead. The risk here is that you take an overly cautious approach, miss out on investment returns, and have less money than you otherwise could have had. That means that you don't have as much money to spend in retirement or you run out of money earlier.

The smartest move I've seen came from a woman who arrived with a plan. She'd worked backwards from the life she wanted. Big spending from 65 to 75, while her knees could handle the travel. A step down through her late 70s. Then a smaller amount of spending in her late 80s.

Her money was set up to match. The cash she needed soon sat somewhere steady. The money for her eighties stayed invested and kept growing, and she shifted it toward safety gradually, over a decade, rather than pulling one big lever on her birthday.

This woman was clued up on investing but that doesn't mean that you can't follow her example. That's where you might use a financial adviser to create a similar plan and move your money for you.

Do you need an adviser for your KiwiSaver?

Many Kiwis don’t realise that they can have a financial adviser for their KiwiSaver. Not a call centre. An actual person who knows your situation, helps you build the plan, checks you're in the right fund, and keeps checking as your life changes. 

Some advisers, like me at Frank Wealth, can work with a scheme called KiwiWRAP. This allows investors to spread their money across multiple investments, rather than just picking one fund manager. 

This gives you more control over your money, and you know exactly where it is invested.

Now, not everyone needs this. If your balance is under $50,000, you actively chose your fund and know what it holds, and you've proven you can leave it alone through a big fall, you're probably fine on your own. 

But if you have over $50,000 in your KiwiSaver, you didn’t choose your fund manager, and you’re not sure what it invests in, then it’s worth discussing with a financial adviser.
