The True Cost Index

What is your provider really costing you?

Every way to invest in New Zealand, ranked by what it really costs: fees, hidden FX, tax, and the cost to leave. No spin.

What you're comparing

Switch between shares/ETFs and crypto, then tap a type to show or hide it. DIY broker = you pick the shares; Managed fund = a fund picks them for you; Advised = a person manages it for a fee.

Ranked cheapest-first by all-in cost: every fee, plus the tax you'll pay, minus the interest each platform pays you on idle cash. It's the real yearly cost of having your money there. Prefer just the platform's charge? Switch to Provider fee. Tap any tag for what it means, or a row for the full breakdown.

The fee funds don't put on the poster.

The headline "management fee" isn't the real number. These are the gaps between what each fund advertises and the total annual fund charges in its official FMA Fund Update: performance fees, underlying-fund costs and admin the marketing page skips.

How the Index is calculated

Every product is reduced to one number: all-in cost as a % of your capital, per year. So a DIY broker, a managed fund and an adviser compare on the same ruler:

  • + Per-buy costs: brokerage, FX spread, bid/ask, fund buy/sell spread
  • + Ongoing: total fund charges, platform, advice fee, flat membership
  • + Tax drag: FIF for direct holders (lower of FDR & CV), PIE (capped 28%), or company (28%)
  • + Cost to exit/switch (amortised over your horizon)

Fees are measured on capital deployed. FIF tax is averaged over the horizon: self-directed holders pay FDR in up years but ~$0 in down years (CV election), so more down years lowers their tax. PIE funds pay every year. The 0–100 score is just the all-in %: 0% → 100, 2.5% → 50, 5%+ → 0.

The tax most pricing pages hide.

For New Zealanders this is usually the biggest cost of all:

  • Direct foreign shares (self-directed) → FIF only over a $50k cost basis (Budget 2026 proposes $100k, not yet law; you can switch to it under Adjust assumptions). You pay the lower of FDR (5% of value) and CV (your actual gain). So a flat or down year is ~$0 tax.
  • PIE funds (Kernel, Simplicity, Smartshares) → taxed in-fund, capped at 28% PIR, but FDR-locked, no CV relief in down years.
  • Investment company → 28%, FDR-locked.

See the maths on eccuity's FIF tax calculator. The $100k threshold proposed in Budget 2026 isn't yet law.

General information only. Not personalised tax or financial advice. Tax depends on your circumstances; confirm with IRD or an accountant. Figures last verified Oct 2026; fees change. Always check the provider's current disclosure (linked in each row).

How the transparency score works

A separate 0–100 score (shown on each row, not folded into the cost ranking) for how openly a platform prices and how easily you can leave. Every product starts at 100 and loses points for practices that hide cost or lock you in:

−30Lock-in: No in-specie transfer. You must sell (and trigger tax) to switch provider
−25Hidden FX: Charges an FX margin but bakes it into the rate instead of showing it as a fee
−20Securities lending: Lends out your shares and keeps the revenue
−15Cash drag: Keeps the interest on your idle cash instead of paying it to you
−10No W-8BEN: Direct foreign shares with no US tax form filed → 30% dividend withholding, not 15%

The score is deliberately kept out of the cost ranking. A cheap but opaque platform still ranks cheap, but you can see what it isn't telling you. Weightings are eccuity's judgement, not an external standard.

Sources & data references

Every fee comes from a primary source: the provider's own pricing/disclosure, the FMA's Sorted Smart Investor & Disclose Register, or IRD. Figures last verified Oct 2026; fees change, so always check the provider's current disclosure. "est." marks a figure we couldn't fully confirm from a primary page.

Disclaimer

Published by eccuity, which appears in this ranking. General information, not a recommendation or financial advice. Tax assumes a 7% return in up years (illustrative, not a forecast), and cash earns each platform’s own rate where it pays one. Competitor fees checked Oct 2026 from each provider’s own disclosures; they change, so check the provider’s current pricing. Tax figures use the current $50,000 FIF threshold, unless you switch to the $100,000 proposed in Budget 2026, which isn’t yet law.
