Step 1 — timeframe first, risk band second
Every NZ fund files a risk indicator from 1 (lowest) to 7 (highest) in its Product Disclosure Statement, computed from its own return volatility. Regulator-published guidance pairs shorter horizons with lower indicators: money needed within a couple of years generally sits in cash or conservative funds; horizons of a decade or more can carry growth or aggressive funds because there is time to sit through downturns. Deciding "when will I need this money" answers most of the risk question before any fund is looked at.
Step 2 — pick the category, then compare inside it
NZ retail funds group into categories — cash, fixed interest (NZ and international), diversified (conservative through aggressive), Australasian equities, international equities, listed property. Fee and return comparisons only mean something within a category: a cash fund charging 0.30% and an international-equity fund charging 1.20% are not alternatives to each other. Category pages on this site list every fund with its disclosed annual fund charge and 5-year after-fee return.
Step 3 — read three numbers per fund, from its own filings
For each candidate fund: the annual fund charge (from the PDS), the after-fee return record (from its Quarterly Fund Update — including the year-by-year figures next to the market index the manager nominated), and the risk indicator. All three are regulated disclosures, so they are comparable across managers. Ignore marketing pages; the QFU is the document the numbers must legally come from.
Step 4 — choose the access route: direct, or via a platform
Most NZ funds can be bought directly from the manager (application form on their website) or through an investment platform such as InvestNow or Sharesies. Direct usually means the manager's stated minimum investment; platforms often lower minimums substantially and put multiple managers' funds behind one login, sometimes adding their own transaction or account fees for certain products. Each fund page on this site shows where that fund is available. Neither route changes the fund's own annual charge — compare total cost across the routes for your balance size.
Step 5 — the paperwork: ID checks and your PIR
Opening any fund account triggers two standard pieces of compliance. First, AML/CFT identity verification — name, date of birth and address, verified against documents like a passport or licence; this is a legal obligation on the manager, not a discretionary hurdle. Second, you supply your IRD number and Prescribed Investor Rate (PIR) — 10.5%, 17.5% or 28%, determined by your income in the last two tax years. An incorrect PIR gets squared up by IRD at year end, but supplying the right one keeps your tax final as you go.
After you invest: what to actually monitor
Fund managers must publish a fund update every quarter and audited financial statements annually — those, not daily unit prices, are the sensible monitoring cadence for most investors. Check that fees have not drifted, that the fund still sits in the risk band you chose, and — for active funds — how the after-fee return tracked the fund's own index. Switching between funds in the same manager is usually a form; switching managers means a redemption (a few business days) and a new application.
