Managed fund in one sentence
A managed fund is a legal structure that pools money from many investors and hires a professional manager to invest it under a published mandate (the investment objective and investment policy sections of the PDS). You buy units in the fund, each representing a proportional slice of the underlying portfolio. The unit price moves with the market value of the portfolio, less fees. You can buy more units (contribute) or sell units (withdraw) on the fund's normal dealing schedule — typically daily for retail unlisted funds, real-time during market hours for NZX-listed ETFs (which are technically also managed funds).
What a managed fund is NOT
A managed fund is not a bank deposit (no Reserve Bank deposit-takers regime cover), not a guaranteed-return product (the unit price can fall), not the same as direct share ownership (you don't own the underlying shares — the fund does, on your behalf), and not the same as KiwiSaver (although every KiwiSaver scheme fund is itself a managed fund — KiwiSaver is the regulatory wrapper around a specific kind of retirement-savings managed fund). It is also not an insurance product, not a derivative, and not a managed account / SMA / wrap platform (those are personalised arrangements; a managed fund is a pooled, identical product for every investor).
How managed funds work — the mechanical bits
Unit pricing: the fund manager calculates a single unit price each business day, typically at 5pm NZ time, based on the closing market value of every holding in the portfolio divided by units on issue. Subscriptions and redemptions: when you buy, the manager issues new units at that price (priced forward — your buy executes at the next available unit price, not the one you saw on the website). When you sell, the manager cancels your units at the next unit price and pays out proceeds usually T+3 to T+7. Mandate enforcement: the manager must invest within the asset-allocation bands and exclusions disclosed in the PDS. A licensed supervisor (trustee) holds the underlying assets in a separate trust structure — if the manager goes broke, your investment is ring-fenced. Distributions: some funds reinvest all income; others pay distributions (monthly, quarterly, or annually) as cash to your nominated account.
Who regulates managed funds in NZ
The Financial Markets Conduct Act 2013 (FMC Act) is the master statute. The Financial Markets Authority (FMA) licenses every fund manager (as a Manager of a Registered Scheme) and supervises ongoing compliance. The FMA Disclose register is the public source of truth — every retail managed fund must have a current Product Disclosure Statement (PDS) + Other Material Information (OMI) + Statement of Investment Policy and Objectives (SIPO) lodged there. Funds also publish a Quarterly Fund Update (QFU) with returns, fees, top 10 holdings, and asset mix. The Inland Revenue Department (IRD) runs the PIE tax regime. The licensed supervisor (typically Public Trust, Trustees Executors, or a specialist firm) holds the assets and watches the manager.
How NZ managed funds are typically structured
A scheme is the legal entity registered with the FMA. One scheme can contain multiple funds — e.g., the Milford Investment Funds scheme (SCH10772) holds Active Growth, Aggressive, Balanced, Conservative, Diversified Income, and other Milford retail funds. Each fund inside the scheme has its own PDS section, mandate, and unit price. Most NZ retail schemes are PIE-structured (Portfolio Investment Entity), which means the wrapper pays tax on your investment income at your PIR (Prescribed Investor Rate, capped at 28%) instead of your marginal rate. Australian-domiciled funds offered to NZ investors are usually NOT PIEs — they're FIF (Foreign Investment Fund), which means you file an annual IR3 return.
Why people use managed funds
Five common reasons. (1) Diversification at small ticket sizes — NZ$1,000 buys exposure to 100-500 underlying companies, which is impossible to replicate with direct share-buying without huge transaction costs. (2) Professional management — for active strategies, you outsource stock selection to people who do it full-time; for passive strategies, the manager handles index reconstitution + dividend reinvestment automatically. (3) PIE tax efficiency — 28% PIR cap saves 5-11 percentage points of tax vs marginal rates for higher earners. (4) Set-and-forget convenience — direct debit fortnightly, automatic dividend reinvestment, single annual tax statement. (5) Access to asset classes that are hard to buy direct — emerging-market bonds, global infrastructure, sustainable-investment portfolios, private credit, etc.
Active vs passive (briefly)
Two main strategy types. Passive / index-tracking funds aim to replicate a published index (e.g., S&P/NZX 50, MSCI World) and charge low fees (~0.07-0.50% per year) because they require minimal stock-picking. Active funds employ analysts and portfolio managers to make stock selections aimed at outperforming a benchmark; they charge higher fees (~0.80-1.80%) and may also charge a performance fee when they beat their hurdle. Neither is universally better. Most NZ investors hold a mix. See our active vs passive guide for the longer comparison.
Costs you need to understand
The annual fund charge (also called MER or total fund charges) is disclosed as a single percentage — it covers management fee, supervisor fee, audit, custody, and underlying-fund expenses, but not transaction costs (brokerage when the fund trades) and not performance fees. A performance fee is an additional charge paid when the fund outperforms a hurdle (e.g., the OCR + 5%), usually capped and subject to a high-water mark. Buy/sell spreads are a one-time charge (5-25 basis points) when you contribute or withdraw, designed to cover the fund's own transaction costs and protect existing unit-holders from dilution. Member fees are flat NZ$ annual charges (e.g., NZ$36/year) — rare on retail managed funds, more common on KiwiSaver. Always compare all-in cost, not just the headline %.
How to start
Three common paths. (1) Direct from the manager — open an account on the manager's website (Milford, Fisher Funds, Generate, Simplicity, Kernel, etc.), verify your ID, set up direct debit. NZ$500-1,000 typical minimum first investment, NZ$50-100 typical regular contribution. (2) Via an online platform — InvestNow, Sharesies (managed-fund channel), Kernel platform — one login across many managers, often lower-cost than going direct. (3) Via a financial adviser — required only for complex situations (estate planning, FIF + PIE combined, large lump sums); an adviser holds a Financial Advice Provider (FAP) licence. For most NZ investors starting out with under NZ$50,000, going direct or via InvestNow / Sharesies is the lowest-friction path.
