ETFs vs Managed Funds in New Zealand: Choosing the Right Structure

An exchange traded fund (ETF) is a managed fund whose units trade on a stock exchange. An unlisted managed fund is the same pooled vehicle bought directly from the manager at a price set from the value of its assets. Both can spread your money across many investments, although diversification depends on what the particular fund holds, and both come in index-tracking and actively managed varieties. The underlying machine is identical. What differs is how you buy, how you sell, and how the tax is worked out along the way.

For most New Zealand investors making regular contributions, particularly anyone on a prescribed investor rate below 28%, the unlisted fund is usually the lower-friction structure. For lump sums, for exposures only an exchange offers, and for anyone comparing ongoing fees rather than entry costs, an ETF can be the cleaner tool. The choice turns on your tax position, your cash-flow pattern, and whether the exposure you want exists in both forms. Each needs a local answer. Much of what you will read on this question is written for Americans, and the tax logic reverses somewhere over the Pacific.

What listing changes

A managed fund is the umbrella term: a pooled vehicle run by a licensed manager who invests for everyone holding units. Listing is the only structural difference. ETF units are bought and sold on an exchange, the way you would trade shares in a company. Unlisted units are applied for directly with the manager, or through an investing platform, and redeemed the same way.

Passive versus active is a separate axis. Index funds, which track a market benchmark instead of trying to beat it, exist in both listed and unlisted form, and so do actively managed funds. Conflating ETF with index fund is a common error. The question here is which structure serves you better once you have decided what to hold.

How you buy, and how the price is set

ETF units trade on an exchange at prices moving through the day. You need a broker or platform, which may charge brokerage on each trade or recover its costs in other ways, and you transact at whatever price a willing counterparty offers. The gap between the buying and selling price, the bid-ask spread, is a cost even though it never appears on an invoice. A market maker usually keeps ETF prices close to the value of the underlying assets. On large liquid funds the spread is thin. On smaller or more exotic ones it can be surprisingly wide.

Unlisted fund units are priced at each valuation point, usually daily, from net asset value. Most funds transact at or very near this price. The application or redemption price may include a disclosed buy/sell spread or transaction charge covering the fund's own trading costs, so the product disclosure statement and latest fund update govern. The trade-off is control. An ETF lets you set a limit price and move while the exchange is open. With an unlisted fund you receive the day's price, whatever it turns out to be, and orders can take a day or two to settle. If you make a scheduled contribution every fortnight, you are unlikely to notice the difference.

Tax: where New Zealand parts company with the global commentary

In the United States, ETFs carry a genuine structural tax advantage over traditional mutual funds, which is why American commentary defaults to recommending them. The advantage stops at the border. New Zealand runs its own regime, the portfolio investment entity (PIE), and the listed versus unlisted distinction cuts quite differently inside it.

Multi-rate PIEs, the most common type and the usual structure for unlisted funds, deduct tax at each investor's own prescribed investor rate (PIR). The rates Inland Revenue currently publishes are 10.5%, 17.5%, and 28%, worked out from your taxable income in the two previous income years and capped at 28%. The rates and thresholds sit on Inland Revenue's prescribed investor rate page and change from time to time, so confirm yours when your income changes. For anyone whose PIR lands below 28%, automatic deduction at your own rate is the single most concrete advantage of the unlisted form: the right amount comes out, and nothing needs claiming back.

Listed PIEs, which include the New Zealand-listed ETF ranges, work on a different mechanism entirely. They are companies. They pay tax at their own basic rate, the 28% company rate, and your PIR never enters the calculation. They pay dividends without resident withholding tax, usually with full imputation credits attached, and Inland Revenue confirms resident individuals can choose whether to include the fully credited dividend in their income tax return. Whether including it helps depends on your income tax position for the year. Suppose a fully imputed cash dividend of $72 arrives carrying $28 of imputation credits, representing $100 of gross income. A person on a 17.5% marginal rate who includes it owes $17.50 of tax while holding $28 of credits, and the $10.50 left over sets against tax on their other income for the year. A person on a marginal rate above 28% who included it would owe more than the credits cover, so they can simply leave the dividend out of the return, as the rules allow. The benefit runs through your marginal income tax rate, which can differ from your PIR because the PIR looks back at two earlier years. And how much value any excess credits deliver depends on the rest of your return, so the election is something to check against your own numbers or with your accountant rather than assume.

Offshore-domiciled ETFs bought through a platform sit outside the PIE regime altogether. Your personal income tax position applies, and the foreign investment fund (FIF) rules can too. Individuals get a de minimis exemption. If your attributing offshore interests cost less than NZ$50,000 in total when you acquired them, whatever they are worth now, you do not need to calculate income under the FIF rules. Above the threshold, tax is generally calculated on a deemed rather than actual return under one of several permitted methods, each with its own conditions, and the administration is yours. Budget 2026 proposed lifting the threshold to $100,000 from 1 April 2026. The change had not been enacted as at August 2026, so $50,000 governs. Inland Revenue's page carries the current position and is worth checking before you rely on either figure. ETFs listed on overseas exchanges can also operate under different investor protections and disclosure standards than New Zealand-offered funds, a point the Financial Markets Authority makes in its guidance on exchange-traded funds.

The PIE structure is no tax haven. For international shares held through a New Zealand PIE, listed or unlisted, a substantial part of the tax calculation generally happens inside the fund on a deemed rather than actual return. Hold the offshore ETF directly instead and a similar calculation may become yours to perform personally, subject to the exemption and method conditions above. The listed versus unlisted gap concerns accuracy, timing, and administration more than the amount of tax ultimately owed. The difference is modest if you are already on 28%, and larger if you are below it.

Trading costs, spreads, and drag

Kernel, an unlisted fund manager and therefore an interested party, argued in an October 2022 article by its founder Dean Anderson the exchange-traded format erodes returns for New Zealand investors. Its estimates, as at 2022: typical retail brokerage between 0.20% and 1.00% per trade, and platform currency conversion around 0.40% per trade on offshore purchases. It also put tax leakage on some internationally invested ETFs, meaning unclaimed credits and treaty benefits, at 0.50% or more a year. Platform pricing has moved considerably since, several platforms now offer low or zero brokerage on selected ETFs, and your own rates sit in black and white on your platform's current fee schedule.

Returns of listed funds can lag their index through tracking difference. The Financial Markets Authority notes it can arise from timing misalignments when assets are bought and sold, and income awaiting distribution as cash is one source. How much it matters varies fund by fund. Because a listed PIE settles tax at company level, how the liability affects the fund's cash holdings and tracking depends on the individual fund. Any claim about drag belongs to a specific fund's quarterly updates, which show its tracking against the index, rather than to the category. The other direction deserves the same treatment. Spreads on the big liquid funds are slim, some ETFs charge lower management fees than their unlisted equivalents, and for a disciplined lump-sum investor on a low-brokerage platform, trading friction shrinks to very little.

What $13,000 a year costs to invest

Take a saver contributing $500 a fortnight, $13,000 a year, into broad international shares. The figures are illustrative placeholders for the ones on your own platform's fee schedule and in each fund's product disclosure statement. Assume brokerage of 0.50% per trade, currency conversion of 0.50% each way, and a bid-ask spread of 0.10% on listed purchases. Annual management fees run at 0.20% for the offshore ETF, 0.30% for the New Zealand listed ETF, and 0.45% for the unlisted fund.

Start with an offshore-domiciled ETF bought directly. Each $500 contribution surrenders about $5 in brokerage and conversion before it reaches the market, roughly $130 a year, with similar charges on the way out plus a conversion back to New Zealand dollars. The fund fee is the lowest of the three, and the tax administration is entirely yours. Your personal income tax position applies, plus a personal FIF calculation once the holdings cost more than $50,000, which this saver reaches during year four.

A New Zealand listed PIE ETF looks different. Brokerage runs about $65 a year at the assumed rate, or nothing where a platform offers zero-brokerage buys on the fund, plus roughly $13 of spread and a 0.30% fund fee. Distributions arrive as cash for you or the platform to reinvest. Tax settles inside the fund at the 28% company rate, and the dividend election above is available where your income tax position makes it worthwhile.

A New Zealand unlisted multi-rate PIE is different again. No brokerage, any buy/sell spread the product disclosure statement discloses, and a 0.45% fee on these assumptions. Tax comes out automatically at your PIR, income is usually reinvested without another transaction, and no FIF calculation lands on you.

Your annual cost is transaction charges on the year's contributions, plus the management fee multiplied by your whole balance, plus spreads on anything traded, plus any tax friction. Transaction charges scale with what you add each year. The fee scales with everything you have already added. Early on, the unlisted route's clean entry wins, delivering about $78 more of each year's contributions to market than the listed route on these assumptions. The listed fund's fee here is 0.15 percentage points lower, and 0.15% of a growing balance eventually beats a fixed $78. Divide one by the other and the crossover lands near $52,000. Below that balance the unlisted fund costs less each year. Above it the cheaper ETF pulls ahead, and it keeps pulling ahead as the balance compounds over two decades. The saver above crosses in roughly year four, sooner with growth. Flip the fee assumption, with the unlisted fund cheaper, and the unlisted route wins at every balance. The formula travels. The inputs come from your own current documents.

What only an exchange can give you

Breadth is the first thing an exchange buys you. Sector, country, and thematic exposures often exist in ETF form long before any unlisted New Zealand fund offers them. Where the exposure you want lives only on an exchange, the debate is over. Control is the other. Live unit prices and market depth are visible while the exchange is open, and limit orders let you set your entry and exit price. Portfolio transparency is a separate matter. New Zealand-offered funds publish quarterly updates showing top holdings, and how much more a manager discloses, and how often, varies fund by fund. Check the documents if full visibility matters to you.

Whole ETF units held through a transferable custody arrangement can often be moved between brokers, subject to each platform's transfer rules and fees. Confirm that before you rely on it. When your PIR is 28%, the multi-rate structure no longer offers you a lower rate, so the accuracy argument for the unlisted form narrows to convenience. The listed fund's fees, distribution policy, and imputation treatment still deserve a look alongside your own income tax circumstances.

Convenience that compounds

The unlisted structure wins on cumulative convenience, which suits long-term savers on autopilot. Your PIR is applied automatically. Contributions typically attract no brokerage, so your fortnightly payment goes in whole, subject to any disclosed spread. Currency conversion on international holdings happens inside the fund at rates the manager negotiates. The holding generally creates no personal FIF calculation and usually no fund-related tax-return work, although you may still need a return for other reasons. Most mainstream unlisted funds price and redeem daily, but the Financial Markets Authority notes some funds require notice periods of days or weeks. The product disclosure statement will say which.

If you belong to a KiwiSaver Scheme you already invest through this structure. The underlying funds are typically unlisted multi-rate PIEs, and your KiwiSaver investment is taxed at your own rate without any action from you.

Questions the comparison raises

Does a New Zealand-listed ETF drag you into the FIF rules personally? No. A New Zealand-domiciled PIE, listed or unlisted, counts as a New Zealand investment for your personal FIF position. Any FIF calculation on its offshore assets happens inside the fund. The $50,000 question only arises for holdings that are themselves offshore, such as ETFs domiciled in the United States or Australia.

Does selling create a capital gains bill? New Zealand has no general capital gains tax, and for a long-term investor selling units in either structure does not usually create a separate tax event. The fund-level or FIF treatment above is the tax story. People who buy with a purpose of resale, or who trade habitually, can be taxed on gains under ordinary income rules, a fact pattern worth professional advice.

Do fractional units change anything? Fractional ETF investing is a platform custody arrangement layered over the exchange. Brokerage follows the platform's schedule, sometimes cheaper than whole-unit trading, and fractions generally cannot transfer between brokers the way whole units sometimes can, so a fractional holding usually moves by selling and repurchasing. Platform terms govern.

What we tell clients

In advisory work the structure question almost always arrives out of order. The asset mix drives your investment risk and your likely return. How you hold it merely changes the friction along the way, and your investment horizon determines how much the friction compounds.

"Clients often arrive convinced the structure is the big decision. It is usually third on the list. Get the asset mix right, get the total cost down, then choose the structure. Where it genuinely bites is on autopilot money. If you are contributing every fortnight for twenty years, brokerage, spreads, and tax you have to claim back become a slow leak, and slow leaks sink ships," says Joseph Darby, Chief Executive of Become Wealth.

Become Wealth is independently owned, with no products of our own to sell. Portfolio construction and allocation follow independent third-party investment research rather than any product shelf, so the recommendation follows your tax position and cash-flow pattern.

Settling it against your own documents

Work through these before you commit.

1. Your tax position: a PIR below 28% favours the multi-rate structure's automatic accuracy, while at 28% the comparison shifts to fees, distribution treatment, and whether the listed dividend election suits your income tax return.
2. Your cash flow: regular contributions favour funds with no per-transaction charge, while lump sums narrow the gap considerably.
3. The exposure you want: where only an ETF offers it, the choice is made for you.
4. Your appetite for admin: offshore ETFs can mean personal FIF calculations and currency fees, while a New Zealand PIE keeps the tax work inside the fund.
5. Your need to trade: intraday pricing only matters if you will use it, and a scheduled saver rarely does.

Then verify the answer against current documents. Your platform's fee schedule carries brokerage, conversion, custody, and transfer-out charges. Each fund's product disclosure statement carries fees, any buy/sell spread, distribution policy, and withdrawal terms. The latest quarterly fund update shows the fees charged and the tracking against the index. And the fund's tax structure, meaning New Zealand multi-rate PIE, New Zealand listed PIE, or offshore, determines whether your PIR, a dividend election, or the FIF rules apply. Many investors sensibly end up with both: an unlisted fund as the workhorse for regular savings, and an ETF or two for exposures the local unlisted market has yet to offer.

What you own matters more than how you own it

The loudest voices in this debate are usually the people selling one structure or the other. What you own will drive nearly all of your result. How you own it decides the friction along the way, and friction is the part you can still control after the market has finished with you.

If you would like a second pair of eyes on those judgements, our investment management team looks at your tax position, cash flow and goals alongside the question of how to hold it. A complimentary initial consultation is the usual starting point. Financial freedom is built on exactly these unglamorous choices, made well and made early.
