Gold ETFs for NZ Investors 2026

IAU charges 0.25% TER vs GLD at 0.40% TER. Over a 30-year hold on NZ$10,000 the cost difference compounds to roughly NZ$450. Both hold allocated physical bullion in vaulted storage. GLD has higher liquidity (the most-traded gold ETF globally) which matters for traders. For NZ buy-and-hold investors, IAU is the clear cost choice; for traders, GLD's tighter spreads can be worth the higher TER.

Physical gold tracks the spot gold price directly with no operational risk. Gold mining companies amplify gold-price moves through operational leverage — a 10% rise in gold typically produces 15-25% rise in GDX (large miners) and 20-40% in GDXJ (junior miners). The amplification works both ways: miners fall further than gold in sell-offs. Miners also carry company-specific risk (operational issues, currency, jurisdiction, financing) that physical gold doesn't.

Above NZ$50,000 cost basis, FIF rules apply (FDR method most common — 5% × opening market value × marginal rate). Physical gold ETFs (IAU, GLD) and silver ETFs (SIVR) pay no distributions, so the only NZ tax mechanic is FDR — no dividend complications or US withholding. Gold mining ETFs (GDX, GDXJ) pay annual distributions which carry 15% US withholding under the NZ-US treaty. The decay-style FIF + FDR interaction does NOT apply to commodity ETFs since there is no leverage.

Smartshares offers NZX-listed funds with global commodity exposure (e.g. Smartshares Total World, which includes some gold-mining names through its broader index). There is no pure-play NZ-domiciled gold ETF currently. For NZ residents wanting gold exposure above the FIF threshold, US-listed (IAU/GLD/GDX) or ASX-listed (GDX.AX, PMGOLD, GOLD.AX) are the available options — both FIF-eligible. ASX-listed gold ETFs have AUD currency layering on top of gold-USD exposure.

Gold has historically had low correlation to equities (-0.1 to +0.3 over 30 years), provides inflation-hedging properties, and can act as a stress-event hedge during currency crises and geopolitical shocks. Typical portfolio allocations are 5-10% of total assets. Gold pays no income, so it costs the FDR floor (5% × MV × marginal rate) every year for NZ residents above the FIF threshold — meaning the diversification benefit must outweigh the after-tax drag. Suitability depends on individual risk tolerance and broader portfolio construction.
