Kernel review – High quality index funds

Kernel is an Auckland-based fund manager who launched in 2019, initially with a modest offering of three index funds. They’ve since refined their product, expanded their range to eleven funds, and are looking to cement themselves as one of New Zealand’s top wealth-building platforms. So are they quickly becoming a worthy challenger among the numerous investment options Kiwis have?

1. What’s on offer


Kernel is a fund manager offering a suite of 11 funds. All funds are index funds – so firstly, what is an index?

An index is designed to measure the performance of a market, or a part of a market. It does this by calculating the collective price movements, and therefore performance, of the selected stocks that are within the index.

Dean Anderson, Founder & CEO, Kernel

For example, the S&P/NZX 20 Index measures and represents the performance of the 20 largest companies listed on the NZX.

Index funds are passively managed and track an index, investing in all of the constituent companies of that index (as opposed to actively managed funds which have fund managers researching and picking what shares to invest in). For example, Kernel’s NZ 20 Fund tracks theS&P/NZX 20 Index, so invests in the 20 companies within that index like Fisher & Paykel Healthcare, Auckland Airport, and Spark.

The result is that an index fund will deliver the same return as that index (as opposed to actively managed funds which aim to outperform the market). Kernel utilises a passive, index tracking strategy for all their funds, with the belief that actively picking stocks in an attempt to beat the market is incredibly hard (and expensive) to do successfully and consistently over the long-term.

Funds on offer

Kernel’s 11 funds are (with the index they track in brackets):

New Zealand funds

  • NZ 20 (S&P/NZX 20 Index) – Invests in the 20 largest companies listed on the NZX.
  • NZ Small & Mid Cap Opportunities (S&P/NZX Emerging Opportunities Index) – Invests in 42 smaller NZX listed companies outside the S&P/NZX 20 Index. Example holdings are Air New Zealand, Vital Healthcare Property, and My Food Bag.
  • NZ Commercial Property (S&P/NZX Real Estate Select Index) – Invests in the eight major Real Estate Investment Trusts (REITs) listed on the NZX. Example holdings are Goodman Property, Kiwi Property Group, and Investore.

Global funds

  • Global 100 (S&P Global 100 Ex-Controversial Weapons Index) – Invests in ~100 of the largest global companies across the world’s sharemarkets. Examples holdings are Apple, Nestle, and Samsung Electronics.
  • Global Infrastructure (Dow Jones Brookfield Global Infrastructure Index) – Invests in 105 companies that derive at least 70% of their revenues from infrastructure type businesses such as transportation, water, or communications. Examples are American Tower Corp, Sydney Airport, and Transurban Group.
  • Global Dividend Aristocrats (S&P Developed Ex-Korea Dividend Aristocrats Quality Income Index) – Invests in 89 companies from around the world that have a strong, stable or growing dividend yield. Example holdings are Exxon Mobil, Pfizer, and Verizon.

Thematic funds

  • Electric Vehicle Innovation (S&P Kensho Electric Vehicles Index) – Invests in 44 companies involved in the electric vehicle ecosystem including manufacturers, and providers of charging infrastructure. Example holdings are Tesla, Blink Charging, and NIO.
  • Moonshots Innovation (S&P Kensho Moonshots Index) – Invests in 49 companies involved in emerging and disruptive sectors such as cyber security, genetic engineering, and space. Example holdings are Virgin Galactic, Dropbox, and iRobot.

Sustainable funds

  • NZ 50 ESG Tilted (S&P/NZX 50 Portfolio ESG Tilted Index) – Invests in the companies of the S&P/NZX 50 index, excluding SKYCITY (for gambling) and Z Energy (for fossil fuels). Each company is weighted up or down according to their ESG score – companies with positive environmental, social, and governance practices make up a larger proportion of the fund, compared to companies with less positive practices. The fund’s largest holdings are Auckland Airport, Meridian Energy, and Fisher & Paykel Healthcare.
  • Global Green Property (Dow Jones Global Select Green Real Estate Securities Index) – Invests in 242 real estate companies from around the world with a heavier weighting towards those who demonstrate high ESG standards. Example holdings are Goodman Group, Scentre, and Simon Property Group.
  • Global Clean Energy (S&P Global Clean Energy Index) – Invests in 71 companies involved in producing clean energy or providing clean energy technology and equipment. Example holdings are Plug Power, Contact Energy, and First Solar.

Quality of funds

Eleven funds isn’t a huge offering, but we wouldn’t consider this a weakness of Kernel as there’s much to like about their range. Most funds offer something unique and there isn’t much overlap between them. Some of their funds are broadly invested funds (like the NZ 20 and Global 100 funds), others are more specialised and exciting (like the Moonshots Innovation and Global Clean Energy Fund) – This makes their range suitable for a core-satellite approach to investing, where a core portfolio of broad market funds is supplemented by a satellite of specialised investments (to spice up what could be a somewhat boring portfolio).

Kernel also take a quality over quantity approach when it comes to their funds. Their focus on quality and efficiency is evident in some of their funds which may appear unusual at first glance. For example:

  • NZ 20 – Most of Kernel’s competitors offer funds based on the broader and more popular NZX 50 index. Kernel chose to offer a NZX 20 fund given the index captures a similar sector composition to the NZX 50 (so are closely correlated in how they move) – but because the NZX 20 has fewer companies, poor performing ones drop out of the index (and therefore the fund) faster than the NZX 50. This is one of the reasons the NZX 20 has outperformed the NZX 50 by 1.58% p.a. over the last 11 years.
  • Global 100 – Global index funds tend to contain thousands of companies, but Kernel’s core global offering contains just 100 companies! Their reasoning is that 100 companies already provides plenty of diversification (e.g. adding a 101st company to a portfolio of 100 will have barely any impact on diversification), is highly correlated to the broader indices that contain thousands of funds, and reduces costs (as there’s fewer companies to buy and sell).

A few of Kernel’s other funds stand out as unique. For example, the NZ Small & Mid Cap Opportunities Fund is the only index fund which invests in companies outside the NZX 50, and their Electric Vehicle Innovation Fund is one of the first EV funds in the world. Kernel is super transparent about their funds too, posting each fund’s entire list of holdings on their website.

They also write blog posts detailing the considerations they’ve made in crafting each fund, and the indexes behind them. They’re worth reading to get a good understanding of each fund and how they might fit into your portfolio. Examples are:

However, their quality offering won’t suit all investors. All of Kernel’s funds invest in shares, so are best suited for longer-term investors – in fact, Kernel’s minimum suggested investment timeframe on all their funds is 5-10 years (and 7-10 years for their thematic and Global Clean Energy funds). Shorter-term investors may find bond and cash investments more appropriate, which Kernel doesn’t offer.

2. Fees

Fund management fee

Kernel charges a percentage based management fee on all their funds:

  • Most funds – 0.39% p.a.

The exceptions are:

  • NZ 50 ESG Tilted – 0.25% p.a.
  • Electric Vehicle Innovation, Moonshots Innovation, and Global Clean Energy – 0.55% p.a.

If you invest over $25,000 with Kernel, they’ll give you a rebate of 0.10% on the management fee, which is paid out in cash to your Kernel wallet every month. This brings their already competitive management fees down to an effective fee of between 0.15%-0.45% p.a.

There’s no transaction fees like spreads, brokerage, or foreign exchange associated with their funds.

Account fee

If you invest $1,000 or more through Kernel, you’ll be charged an account fee of $3 per month ($36 per year). This can be a bit high for smaller balances – for example, $36 equates to a 3.60% fee on a $1,000 account.

The below table shows the total annual fees (fund management fee + account fee) for investing various amounts of money into the NZ 20 Fund:

Amount investedTotal fee
$500$1.95 (0.39%)
$1,000$39.90 (3.99%)
$10,000$75 (0.75%)
$25,000$108.50 (0.43%)
$50,000$181 (0.36%)
$100,000$329 (0.33%)

This fee structure would suit those who are:

  • Just trying out Kernel (or investing in general) with a small amount of money.
  • Investing a large amount of money – especially over $25,000 to qualify for the 0.10% fee rebate.
  • Committed to growing their portfolio larger over time, so that the $36 fee is spread across a larger portfolio.

However, Kernel would be expensive for those planning to invest only a couple of thousand dollars into their funds.

3. Other considerations

Minimum investment

The minimum investment on Kernel is $1 per fund.

Investment bundles

Kernel offers two investment bundles – a pre-made package of funds which aim to make selecting what to invest in easy:

  • Core Bundle – Contains 3 broadly invested funds – Global 100 Fund, NZ 20 Fund, and NZ Small & Mid Cap Opportunities Fund.
  • High-growth bundle – Contains the above 3 core funds, with smaller allocations towards the Global Infrastructure, Global Green Property, and NZ Commercial Property funds.

The High Growth Bundle is more suitable for those with a significant lump sum ($50,000+) to invest and then further contribute, because the allocation to property and infrastructure should reduce the overall portfolio volatility due to the their lower correlation to other equity sectors.

Kernel’s auto-invest functionality enables you to invest in their funds or bundles automatically on a weekly, fortnightly, or monthly basis.

Order execution

While you can place orders to buy and sell units in their funds at any time, Kernel only execute their orders two times per week on Mondays and Wednesdays (with a cut off time of 12pm on each day). In the worst case, if you placed an order on Wednesday afternoon, it wouldn’t be executed until Monday!

This may seem like an odd process, and some investors won’t be fans of it. But this discourages constant trading, reduces transaction costs, and helps improve efficiency (they keep very little cash in their funds meaning more of your money is invested in shares). A few days delay in processing your order won’t matter if you’re investing for 10+ years as a genuine long-term investor.


All of their funds (except for the thematic and Global Clean Energy funds) pay distributions on a quarterly basis. You can choose to have these automatically reinvested, or paid out in cash.


All of Kernel’s funds are Multi-Rate PIEs so are taxed at your Prescribed Investor Rate. They calculate your tax obligations for you, which is payable after the end of every tax year (31 March) or whenever you sell units of a fund. Any tax liability will be deducted from your Kernel account’s cash balance.

Currency hedging

Most of Kernel’s international funds don’t use currency hedging, so their value will be impacted by exchange rate fluctuations. Only the Global Green Property Fund is hedged to the NZD, which removes most of the exchange rate volatility.

Account types

Kernel offers individual, joint, kids, company, and trust accounts.

User friendliness

Kernel provides a modern, mobile-friendly digital platform for investors to view and manage their investments. If you get stuck, support is available through phone or email.

Investor education

Kernel has a few initiatives to improve people’s investing and financial literacy, and are probably one of the better producers of educational content. They have a good blog, hold regular in-person events (pre-COVID-19 lockdowns), and host webinars. In addition, Cat and Christine from the Kernel team host the It’s No Secret podcast. The podcast isn’t directly Kernel related though – instead covering a broad range of personal finance topics.

4. Kernel vs competing services

It’s quite hard to compare Kernel with other platforms, given many of their funds are unique for the NZ market (and even globally!). But here’s a brief overview of how Kernel stacks up to competing services:


Smartshares is another index fund provider who offer 35 funds, some of which are somewhat close (but not necessarily like-for-like) alternatives to Kernel’s funds:

  • The Smartshares S&P/NZX 50 ETF or NZ Top 50 ETF are alternatives to the NZ 20 or NZ 50 ETF Tilted funds.
  • The Smartshares NZ Mid Cap ETF is an alternative to the Small & Mid Cap Opportunities Fund.
  • The Smartshares Total World ETF or US 500 ETF are alternatives to the Global 100 Fund.
  • The Smartshares NZ Property ETF is an alternative to the NZ Commercial Property Fund.

Though not all of Smartshares and Kernel’s funds overlap. Smartshares has a more comprehensive offering including funds that cover more specific geographies and sectors such Europe, Emerging Markets, and Australian Resources. Smartshares also have a couple of thematic funds in the form of an Automation and Robotics ETF and Healthcare Innovation ETF, and funds that invest in more conservative bond and cash assets. However, a few of Smartshares’ funds overlap with each other and can be confusing for investors. Many of Kernel’s funds like the Global Infrastructure and Global Dividend Aristocrats funds don’t have a Smartshares alternative.

Another key difference is that Kernel’s funds are unlisted, while Smartshares’ funds are ETFs (listed on the NZ sharemarket and available through brokers like Sharesies and platforms like InvestNow). Kernel argues unlisted funds provide a more efficient structure in terms of tax and trading costs, though there isn’t a massive fee difference between the two providers. Smartshares’ fees range from 0.20% to 0.75%, and it’s possible to avoid any account and brokerage fees if you use InvestNow (though you’ll still pay spreads). Ultimately the best option for you will depend on exactly which funds you’re investing in, and how much you’re investing.

InvestNow is a fund platform offering over 150 funds from 27 different fund managers. Most are actively managed, but they still have a decent passive range from AMP, Vanguard, Foundation Series, and the above Smartshares ETFs. Their lack of brokerage or account fees, make for an attractive option.

The key downsides of InvestNow are their higher minimum investment of $50 per fund versus Kernel’s $1 per fund, inferior user interface, and cash drag from not being able to buy fractional units in Smartshares ETFs.

Simplicity‘s key offerings are their diversified funds which contain a mix of local and international shares and bonds. This makes it incredibly simple to put a well-rounded portfolio together without having to worry about what individual funds to pick. Simplicity’s fees are comparable, charging 0.31% + a $20 annual management fee.

However, you lose flexibility in being able to choose exactly what asset allocations to invest in. For example, in their Growth fund you’re stuck with their prescribed allocation of ~22% towards cash and bonds, which some people consider to be not aggressive enough. Meanwhile Kernel allows you to select exactly how you want to allocate your portfolio towards each sector out of their NZ, global, thematic, and sustainable funds.

Sharesies, Hatch, Stake

Sharesies, Hatch, and Stake are not direct competitors to Kernel, given their focus as brokers for individual share and ETF investments. You’ll get much more choice in investment options with these platforms, while Kernel represents a much more simple way to invest.

Some of the US listed ETFs they offer may be compelling alternatives to Kernel’s funds. For example, the Vanguard Total World Stock ETF could be used as an alternative to the Kernel Global 100 Fund and has a lower management fee (0.08% vs 0.39%). But don’t forget you also have to pay foreign exchange and brokerage fees on Sharesies, Hatch, and Stake, compared with none on Kernel. In addition, these platforms may require more work when it comes to taxes given the FIF status of US ETFs. There is no definitively best option, and the one that works best for you will come down to your investing behaviours and preferences.


Kernel doesn’t offer many bells and whistles like the ability to pick from thousands of individual stocks and ETFs, participate in IPOs, or trade in and out of your funds daily – but Kernel isn’t built for that type of investor. They’re best suited to investors wanting to keep their portfolios simple and down-to-earth by investing long-term in a carefully considered range of index funds. And they still have plenty of features like auto-invest, bundles, and easy-to-digest blog posts to help you along on your investing journey.

Kernel’s fees are generally competitive, though investors should be careful of their $36 fee annual account fee which makes them expensive for smaller portfolios. Aiming to invest over $25,000 would provide the best value and make you eligible for their 0.10% fee rebate. Overall, while Kernel’s range of investment options is relatively small and provides less flexibility, their funds are high quality and quite unique. We consider Kernel to be a solid alternative to investing through the likes of Smartshares and InvestNow, and being a relatively new provider we can expect many further refinements and improvements in the coming years.
