Quick Answer
Rental yield is the annual rent income expressed as a percentage of a property's purchase price. In New Zealand, a gross yield of 5–7% is generally considered strong for residential investment property. Gross yield divides annual rent by purchase price and ignores expenses; net yield deducts running costs (rates, insurance, property management, maintenance) and typically runs 1.5–2.5 percentage points lower. Regional cities like Gisborne (7.5–8.5% gross) and Palmerston North (6.5–7.5%) offer the highest NZ yields; Auckland is the lowest at 3.5–4.5%.
What Is Rental Yield?
Rental yield is the annual return you earn from a property as a percentage of its value. It is the single most useful number for quickly comparing investment properties — a higher yield means more income relative to what you paid.
There are two versions: gross yield, which uses rent alone, and net yield, which deducts all your running costs. Both matter, but they tell you different things.
How to Calculate Gross Yield
Gross yield is the quick-and-easy benchmark. It only uses rent and purchase price — no expenses. Useful for screening properties at speed, but it overstates your actual return.
$28,600 ÷ $620,000 × 100 = 4.61%
How to Calculate Net Yield
Net yield is what you actually earn after paying the costs of owning the property. It is a more honest measure of performance — two properties with the same gross yield can have very different net yields depending on rates, insurance, and management costs.
Expenses to include:
- Council rates — typically $2,500–$5,000 per year depending on property and region
- Building and landlord insurance — typically $1,500–$3,500 per year
- Property management fees — typically 7–10% of gross rent if you use an agent
- Maintenance and repairs — budget 1% of property value per year as a rule of thumb
- Vacancy allowance — assume 2–4 weeks per year of no rent
- Accounting and legal fees — annual tax return preparation, lease renewals
- Body corporate fees — for apartments, add annual levies
Gross yield was 4.61% — net yield is 2.19%. The gap is larger than most new investors expect.
Yield calculations do not include mortgage interest payments. Yield measures the return on the asset — not on your equity. Cash flow (income minus all costs including mortgage) is the separate metric that tells you whether the property puts money in your pocket each week.
When to Use Gross vs Net Yield
Use it for quick screening
Gross yield is fast to calculate and lets you compare dozens of listings quickly. Use it to filter out clearly low-yielding properties before doing deeper analysis. Most published yield benchmarks and city comparisons use gross yield because the data is easier to standardise.
Use it for real decisions
Net yield is what you should base purchase decisions on. It reflects what the investment actually earns after costs. Two properties with the same gross yield can have very different net yields — an older home may need far more maintenance than a new build, and an apartment has body corp fees a house doesn’t.
What’s a Good Yield in New Zealand?
A gross yield of 5% or above is generally considered solid for NZ residential property. Below 4% gross is weak — you are relying heavily on capital growth to make the numbers work. Regional cities consistently out-yield Auckland and Wellington, often by 2–3 percentage points.
Regional cities offer stronger yields but tend to deliver more modest capital growth. Auckland and Wellington have historically shown stronger long-term capital appreciation but low yields — meaning investors rely on property values rising to make returns work. The right choice depends on your strategy: income now or wealth later.

What Affects Rental Yield?
Understanding what drives yield helps you spot opportunities and avoid traps when evaluating a property.
How to Use Yield to Compare Properties
Yield is most powerful when used to compare multiple properties on a like-for-like basis. Here is a structured approach:
- Start with gross yield to shortlist. Filter out anything below your minimum threshold (e.g. 5% gross) before spending time on deeper analysis.
- Use market rent, not the current tenancy rent. If an existing tenant is paying below-market rent, calculate yield on what the property would realistically rent for today — not what is currently being received.
- Calculate net yield before making an offer. Get actual quotes for rates, insurance, and management fees before committing. Assumptions can be wildly off for different property types.
- Check yield at different purchase prices. If you negotiate $30,000 off the asking price, recalculate yield at the new price — the improvement can be meaningful.
- Never compare yield alone across different cities. A 6% yield in Gisborne carries different risk and liquidity characteristics than 6% in Christchurch. Yield is one input, not the whole picture.
Yield Mistakes That Cost Investors
- Using current rent on a below-market tenancy. If the tenant has been there 5 years, their rent may be 15–20% below market. Calculate yield on current market rent, not the existing rate.
- Ignoring vacancy. Even in tight rental markets, vacancy happens. A property that sits empty for 4 weeks costs you nearly 8% of your annual rental income in that year.
- Treating gross yield as the real return. Gross yield is a shortcut, not a result. Investors who skip net yield calculations often find their actual return is half what they expected.
- Forgetting maintenance on older properties. A 1% annual maintenance allowance is conservative for homes over 30 years old. Budget higher, especially for weatherboard, iron roofing, or timber joinery.
- Calculating yield on RV instead of purchase price. Rateable Value (RV or capital value) is often significantly below or above market. Always use what you actually paid, or the price you are negotiating to pay.
