“ETF” and “managed fund” are terms NZ investors often see together, but they’re not interchangeable: they describe two ways of holding a fund, with different pricing, costs and access. Managed funds NZ covers how managed funds work and their PIE tax in full.
Both ETFs and managed funds can be index funds (passive). The key difference is how you buy them: ETFs are bought and sold on a stock exchange (NZX) during trading hours, like shares. Managed funds are bought directly from the fund manager or a platform (like InvestNow or Kernel) at the end-of-day price. Directly-accessed managed funds (such as those on InvestNow, Kernel, and Simplicity) support regular automated investing without brokerage.
The Core Distinction
| ETF (Exchange-Traded Fund) | Managed Fund (Unit Trust) | |
|---|---|---|
| How to buy | Via a stock exchange (NZX or US) through a broker | Directly via fund manager or platform |
| Pricing | Real-time during trading hours | Once per day (NAV, end of day) |
| Minimum investment | 1 unit on the exchange, or a dollar amount on platforms that take fractional orders; $500 direct with Smart (formerly Smartshares) | Varies: $1 (Kernel), $250 (InvestNow), $1,000 (Simplicity) |
| Auto-invest | Through brokers that offer it, or Smart’s regular plan | Built into most platforms |
| Brokerage | Yes: typically $1 to $30 per trade | No brokerage on managed funds |
| PIE tax status | Most NZ ETFs are PIEs | Most NZ managed funds are PIEs |
Are ETFs Always Index Funds?
In NZ, most ETFs are passive (index-tracking). Smart ETFs (formerly branded Smartshares; renamed September 2024), for example, all track indices. In the US, the vast majority of popular ETFs are also index funds (SPY, VOO, IVV).
However, actively managed ETFs exist globally. And many managed funds are actively managed (Milford, Fisher Funds).
The term “index fund” describes the strategy (passive, tracks an index). The terms “ETF” and “managed fund” describe the structure (how you access it).
What ETFs Offer
The same account as your shares. Sharesies and Tiger Brokers, which sell NZX shares, also sell Smart ETFs (such as USF, TWF and NZG, formerly branded Smartshares), so they can be held alongside shares without a new account.
Intraday pricing. ETFs can be bought or sold during NZX trading hours at the market price. Managed funds process applications and redemptions at an end-of-day price.
Exchange trading for large orders. On a large order, the bid/ask spread and how the order is executed affect the price paid.
What Direct Managed Funds Offer
Regular auto-invest. InvestNow, Kernel and Simplicity take regular contributions into their funds. ETFs can be auto-invested through a broker that offers it (Sharesies’ plans, for example, cover a set value of auto-invest orders each month) or through Smart’s regular plan.
No brokerage. A Smart ETF bought through a broker carries the broker’s fee: Sharesies charges a 1.9% transaction fee on orders below its caps ($25 NZD for NZ shares), checked 14 October 2026. Managed funds bought on InvestNow or Kernel carry no brokerage, though some InvestNow funds charge a buy/sell transaction fee (see the cost comparison below). On small regular amounts, a percentage brokerage fee is charged on every contribution.
Dollar amounts. Managed funds accept a dollar amount and issue fractions of a unit. On the exchange itself ETFs trade in whole units, but some NZ platforms take fractional orders: Sharesies’ pricing page (checked 14 October 2026) describes “limit buy orders in whole or fractional shares”.
No trading hours. Applications go in at any time and are processed at the next end-of-day price.
NZ ETF vs Managed Fund: Cost Comparison
Scenario: $5,000 initial investment, $200/month regular contribution, global index fund
Smart Total World ETF (TWF, via Sharesies) — formerly Smartshares
- ETF fee: 0.40% p.a. → ~$20/year on a $5,000 balance
- Sharesies platform fee: $0 ongoing (Sharesies dropped its % AUM platform fee; it now charges per-trade brokerage instead)
- Brokerage: 1.9% per order (capped at $25 NZD) — on a $200 monthly purchase that’s $3.80/month, ~$46/year; plus a one-off ~$25 on the initial $5,000 lump sum
- Total effective ongoing cost on $5,000: ~$66/year (plus a one-off ~$25 brokerage charge when first investing the lump sum)
InvestNow Foundation Series Total World Fund
- Fund fee: 0.06% p.a. (plus a 0.50% buy/sell transaction fee on each contribution)
- InvestNow platform fee: $0
- Brokerage: $0
- Total effective ongoing cost on $5,000: ~$3/year, plus the one-off 0.50% transaction fee on each amount invested (e.g. $25 on the initial $5,000, $1/month on a $200 contribution)
In this scenario the InvestNow fund costs less each year, mainly because the ETF route pays brokerage on every monthly purchase and has a higher annual fund fee. A larger balance, fewer purchases or a paid broker plan changes the gap.

NZ-Accessible Global ETFs (US-listed)
US-listed ETFs like VOO (Vanguard S&P 500, 0.03%) can be bought via Hatch, Stake, or Tiger Brokers. Their fund fees are low, and their tax treatment differs:
- FIF tax applies above $50,000 in overseas shares
- Not PIE funds: dividends are taxed at your marginal rate
- Currency risk without hedging option

How They Compare by Situation
| Situation | What the structures offer |
|---|---|
| Regular automated investing (DCA) | Managed funds (e.g. on InvestNow or Kernel) support auto-invest without brokerage; ETFs through a broker’s auto-invest or Smart’s regular plan |
| Already have an NZX broker (Sharesies/Tiger) | Smart ETFs (TWF or NZG, formerly Smartshares) can be bought through it |
| Large lump sum, want immediate execution | Little practical difference between the two |
| Lowest annual fee in this comparison | Foundation Series US 500 Fund (InvestNow, 0.03%) and Foundation Series Total World Fund (InvestNow, 0.06%) |
The differences come down to how often you invest, how much at a time, and what you want to hold.
