Kernel KiwiSaver Scheme Review

Kernel KiwiSaver Scheme Review

Kernel runs 25 KiwiSaver funds open to new members, spanning almost the whole of the register’s risk scale. At 30 June 2026 they held $1.19 billion for 28,647 investors. The funds run from risk level 1 to 6, so which fund you pick matters more than which scheme you are in.

Charges across the open funds run from 0.25 per cent to 0.45 per cent.

Over five years the Kernel S&P Global Dividend Aristocrats Fund returned 9.63 per cent a year while the Kernel NZ Commercial Property Fund returned -2.75 per cent a year, which is the gap between the top and the bottom of what you can choose from.

What follows is set out in three parts. First, what the scheme actually holds. Second, the fees, risk indicators, and returns for every fund are read off the Government’s register. Third — and this is the part that matters — whether the return justifies the charge.

How We Researched This Guide

Every number below is read from our own copy of the Government’s Disclose Register, which is the statutory source managers file against. It carries 25 open funds, all reported as at 30 June 2026.

We also checked the rules that underpin every KiwiSaver account — contribution rates, the government contribution, and default provider appointments — against Inland Revenue and the Ministry of Business, Innovation and Employment.

This guide is not here to tell you to switch or to stay. What it does is put the verified numbers in one place so you can compare on facts rather than marketing.

What You Pay, and What You Get For It

Kernel charges an annual fund charge, and there are no separate membership, contribution, establishment, switching or termination fees recorded for its KiwiSaver scheme. The charge comes out of the fund’s returns rather than being billed to you, which is why most members never see it leave the account.

It helps to see the charge in dollars. On a $50,000 balance, the lowest charge here, 0.25 per cent, is about $125 a year, and the highest, 0.45 per cent, is about $225. On $100,000, those figures double.

What the Charge Costs at Different Balances

The figures below convert the percentages into annual dollars at three balances. The fee is the one part of the arrangement that does not depend on market performance.

What makes a fund charge costly is its repetition. It is deducted every year from the whole balance, so the money it removes cannot itself earn a return in later years.

The Kinds of Fund in This Range

The register groups every fund by type, and the type tells you more about the risk than the name does. Kernel spans 4 of those groups, which determines how much choice you actually have.

The risk indicator runs from 1 to 7. It measures how much the fund’s value has moved in the past, not how good it is. A 6 or 7 is not a warning; it is a statement that the fund is expected to fall further in a bad year, and it belongs in a portfolio you will not need to touch for a long time.

Kernel KiwiSaver Plan — the funds

Charges across the open funds run from 0.25 per cent to 0.45 per cent. The strongest five-year figure is the Kernel S&P Global Dividend Aristocrats Fund at 9.63 per cent a year, and the weakest is the Kernel NZ Commercial Property Fund at -2.75 per cent a year.

What the Funds Actually Hold

The register also discloses each fund’s split between growth assets, such as shares and property, and income assets, such as bonds and cash. More than the fund’s name, that ratio tells you how it will behave when markets move.

Between 0% growth assets in the Kernel Cash Plus Fund and 106% in the Kernel Global ESG (NZD Hedged) Fund, this range covers a lot of ground. The lower figure is built to protect capital; the higher one is built to grow it, and will lose more when markets fall. Match the fund to your horizon rather than to last year’s return.

Reading the Returns

Every return shown is net of the fund charge and after tax — the figure a member actually experiences. Every return shown is net of the fund charge and after tax. The strongest five-year average here is the Kernel S&P Global Dividend Aristocrats Fund at 9.63 per cent a year, against a range of -2.75 to 9.63 per cent across the open funds.

Read the one-year and five-year columns together rather than separately. One-year figures across these funds span 0.59 to 96.03 per cent, and five-year averages -2.75 to 9.63 per cent. A single year reflects twelve months of market conditions; a five-year average is much harder to flatter, and it is the fairer basis for comparing managers.

That difference between one strong year and a five-year average is the most useful thing to understand before you pick a fund. It is also why a fund with a short history is harder to judge: there is simply less to judge it on.

Below are all the returns the register publishes, fund by fund. Weight the longer columns most heavily — they are the ones a manager cannot produce by luck.

There are 25 open funds in total, and the table above shows the fifteen largest by value. Every fund is listed with its charge and one-year and five-year figures in the earlier tables, so you can check the rest there.

22 of the open funds here have no five-year figure because they have not been running that long. We show a dash rather than a number that wouldn't be comparable, so weigh those funds by their fee and strategy instead.

Where Kernel Sits Against the Alternatives

On entry cost, Kernel is the 6th cheapest of the 29 managers in our KiwiSaver table, with its cheapest fund charging 0.25 per cent. The cheapest manager charges 0.03 per cent and the dearest starts at 4.26 per cent.

Cheap is not the same as good. The test is whether the manager returns what the fee costs, and that shows up in the five-year figures. Past performance is not a promise, and any period that favours one asset class will flatter the funds holding most of it.

What You Put In, and What You Get Back

What you contribute is a matter of law and your own choice, not of who your provider is. The provider’s influence begins once the money is in, which is why the fund charge grows in importance as the balance does.

The default employee and employer rate is 3.5 per cent from 1 April 2026, and it rises to 4 per cent on 1 April 2028. On a $70,000 salary, 3.5 per cent is $2,450 a year from you, matched by your employer, so about $4,900 a year goes into the account before any return.

The Government adds 25 cents for every dollar you contribute, up to a maximum of $260.72 a year. To receive the full amount, you must contribute at least $1,042.86 of your own money between 1 July and 30 June, and employer contributions do not count towards that threshold. If your taxable income is above $180,000 a year, you do not qualify.

Once the money is in, the fund charge applies to the whole balance rather than to each contribution. On a $50,000 balance, the lowest charge here, 0.25 per cent, is about $125 a year, and the highest, 0.45 per cent, is about $225. On $100,000, those figures double. That is the number worth weighing against the returns, because it is charged whether the fund rises or falls.

Questions You Might Have

Which fund am I in?

Your KiwiSaver statement, or the online account you use to manage your savings, will show which fund your money is invested in and how it is split if you hold more than one. Check it before anything else, because the fund decides both the return and the charge.

How much will I pay?

Charges across the open funds run from 0.25 per cent to 0.45 per cent. It comes out of the fund’s returns, not your bank account, so you will not see a separate bill.

Is Kernel a default provider?

No. The appointed default providers are BNZ, Booster, Westpac (through BT Funds Management), Fisher Funds, Simplicity and Smartshares, with appointments running to December 2028. Kernel is a scheme you choose deliberately.

Can I change funds without changing provider?

Usually yes. Most schemes let you move between their own funds, or set a different split, through your online account at no cost, and the change takes effect without affecting your membership or your employer contributions. You only need to switch provider if the scheme itself is the problem.

Do I have to pick just one fund?

No. With 25 open funds, you can split your balance across several, which lets you take more risk with part of your savings and less with the rest. The trade-off is that you have to keep track of the split yourself.

What happens to a closed fund?

If you already hold a fund that has closed to new members, you keep it and continue to pay the charge shown. Closing a fund stops new money coming in; it does not force existing members out, and it does not change your balance.

How much do I need to contribute to get the full government contribution?

You need to put in at least $1,042.86 of your own money between 1 July and 30 June to receive the maximum of $260.72. The government adds 25 cents for every dollar you contribute, and employer contributions do not count towards your $1,042.86. If your taxable income is above $180,000 a year, you do not qualify.

How much will I pay at the default contribution rate?

The default employee and employer rate rose from 3 per cent to 3.5 per cent on 1 April 2026, and it rises again to 4 per cent on 1 April 2028. On a $70,000 salary, 3.5 per cent is $2,450 a year from you, matched by your employer. You can choose 4, 6, 8 or 10 per cent instead.

Does switching to or from Kernel cost anything?

No. Kernel records no membership, contribution, establishment, switching or termination fees, and switching between KiwiSaver providers does not attract a fee in practice. You apply to the new provider, who arranges the transfer.

Why do some funds have no five-year figure?

Because they have not been running for five years. A fund launched in the last few years cannot have a five-year return, so the register leaves it blank rather than showing a figure that would not be comparable. We show the same dash.

What Matters Most

Kernel is a provider with a wide range of funds. The fee table above shows the current charges for each fund. The funds are numerous enough that you need to choose deliberately.

• The Kernel Australia 100 Fund is the cheapest way in at 0.25 per cent.
• The strongest five-year record is the Kernel S&P Global Dividend Aristocrats Fund at 9.63 per cent a year, and it carries the risk that produced it.
• 22 funds are too new to have a five-year record, so judge them on strategy and fee rather than past performance.
• Check which fund you are in before anything else, because it decides both the return and the charge.
