For most New Zealanders, property and shares represent the two main paths to long-term wealth. The debate is vigorous, the opinions are strong, and the correct answer depends heavily on individual circumstances. Here’s an evidence-based comparison.
Both have created wealth for NZ investors over the long run. Property benefits from leverage (you borrow to invest) and is tangible. Shares are more accessible, more liquid, more diversified, and have lower ongoing costs. The "best" choice depends on your deposit size, ability to service debt, risk tolerance, and time available to manage a property. Many investors ultimately hold both.
Historical Returns: NZ Property vs Shares
NZ property (residential, nationwide)
- Average capital growth: approximately 5–7% p.a. over 30 years (nominal; includes significant 2010–2021 period of exceptional growth)
- Rental yield: 3–5% gross (before costs and tax), varies significantly by location and property type
- Total gross return: approximately 8–12% p.a. (capital + yield) for leveraged investors in strong periods
- Key caveat: Leverage amplifies these returns. An investor who put in $100,000 deposit and borrowed $400,000 to buy a $500,000 property benefits from returns on the full $500,000 value — not just their $100,000.
NZ and global shares (unhedged)
- NZX 50: approximately 7–9% p.a. total return (capital + dividends, nominal) over 20 years
- Global shares (NZD): approximately 9–12% p.a. over 20 years (including currency movements favourable to NZ investors)
- No leverage required: You invest exactly what you have
The Role of Leverage
This is the key structural difference. Property investors typically borrow 60–80% of the purchase price. Shares investors typically don’t borrow.
Example — $100,000 to invest, 10-year horizon, 8% annual return on the asset
| Strategy | Asset value | Your equity | 10-year return on equity |
|---|---|---|---|
| Shares: invest $100k directly | $100,000 | $100,000 | ~$116% ($216k) |
| Property: $100k deposit, borrow $300k | $400,000 | $100,000 | ~415% ($515k equity after 10yr) |
Highly simplified. Property return calculated assuming 8% growth on full asset value minus mortgage repayment cost at 6.5%. No rental yield included in this simplified example.
The leverage effect explains why property has created so much wealth in NZ — investors used bank debt to control large assets. But leverage amplifies losses just as it amplifies gains. A 20% property price fall on a 80% LVR investment wipes out the entire equity.
True Costs: Shares vs Property
Shares’ costs are simple. Property’s costs are substantial and often underestimated.
Shares costs (annual)
- Fund fee: 0.10%–0.50% p.a.
- No other ongoing costs for index funds
Property investment costs (annual)
- Mortgage interest (at 6.5%: $19,500/year on $300,000 loan)
- Insurance: $2,000–$4,000/year
- Rates: $3,000–$5,000/year
- Property management (if used): 8%–10% of rent
- Maintenance/repairs: 1%–2% of property value/year
- Vacancy periods: 2–4 weeks/year average
On a $500,000 rental property, total ongoing costs (excluding mortgage) can easily reach $15,000–$25,000/year. Net rental yield after these costs is often 1–3% — much lower than the gross yield.
Tax: How Each Is Treated
Shares (PIE funds)
- Tax paid at PIR rate (10.5%, 17.5%, or 28%) on fund returns annually
- No capital gains tax on sale for NZ investors
- Dividends taxed at PIR within PIE funds
Rental property
- Rental income taxed at marginal rate (up to 39%)
- From 2024, mortgage interest is again deductible (interest deductibility was removed 2021–2024, now being phased back in; 80% deductible in 2024, 100% from April 2026)
- Repairs and maintenance deductible
- Bright-line test: Properties sold within 2 years trigger income tax on gains (bright-line dropped from 10 to 2 years from July 2024)
- No capital gains tax on sale beyond 2-year bright-line test
The return of mortgage interest deductibility in 2026 significantly improves rental property economics vs 2022–2024.
Liquidity and Flexibility
Shares: Can be sold in 1–3 business days. Partial sales are easy — you can sell $5,000 of a $50,000 fund without disrupting the rest. Low minimum to add or reduce investment.
Property: Selling takes weeks to months. Significant transaction costs (agent fees 2%–3%, legal fees ~$2,000, potential conveyance). Cannot sell 10% of a property. Capital is locked in until sale.
For investors who may need access to capital, shares win significantly on liquidity.
Time and Effort
Shares (index funds): Minimal. Set up auto-invest, review annually, do nothing else.
Property: Substantial. Tenant screening, maintenance coordination, compliance (healthy homes standards, Residential Tenancies Act), dealing with vacancies, repairs, disputes. Even with a property manager (additional cost), property requires active engagement.
Concentration Risk
A single rental property in Auckland puts a significant portion of your net worth in:
- A single asset
- A single city
- A single asset class
- Illiquid form
An index fund spreading $100,000 across 1,500 global companies across 20+ countries has near-zero concentration risk. A single Auckland apartment that needs $80,000 in earthquake repairs or has a problem tenant for 6 months is devastating.
Property vs Shares: By Situation
| Situation | Lean toward |
|---|---|
| Have $500k+ in home equity to leverage | Property (leverage access) |
| Starting out with $10k–$50k | Shares (accessible, diversified) |
| High income, good at managing tenants | Property |
| Time-poor, want passive investment | Shares |
| Want liquidity in 5–10 years | Shares |
| Long time horizon (15+ years), can access leverage | Either — personal preference |
| Already own a home, want diversification | Shares (home provides property exposure) |
| Strong local property knowledge, active investor | Property |
The Combined Approach
Most NZ wealth-builders don’t make a binary choice. A common profile:
- Own and pay off a home (property exposure, forced savings via mortgage)
- Invest surplus income into global index funds (diversification, liquidity, low cost)
- If they want additional property exposure: consider REITs (listed property trusts) rather than direct ownership — the liquidity and diversification benefits of shares with property as the underlying asset
This approach avoids concentration in either direction and captures the compounding benefits of both.
Frequently Asked Questions
Is Auckland property still a good investment in 2026? Auckland property prices have corrected 15–20% from their 2021 peak and have stabilised in 2025–2026. Gross rental yields in Auckland remain low (3–4%) relative to other NZ cities. Strong population growth supports long-term demand. It can be a good investment for the right investor but requires significant capital and management commitment.
What about the bright-line test? Properties sold within 2 years of purchase have gains taxed as income. Properties held longer have no capital gains tax. This favours long-hold investment strategies. See Bright-Line Test NZ.
Should I pay off my mortgage before investing in shares? At a 6.5% mortgage rate, paying down the mortgage gives a guaranteed 6.5% return. Historical share returns of 8–10% suggest investing has a slightly higher expected return — but with no guarantee. A common middle path: make minimum mortgage overpayments AND invest simultaneously, splitting the surplus.
