Rental Yield Calculator for New Zealand

Summary

Rental yield measures the annual return from renting out a NZ investment property, expressed as a percentage of the property price. Gross yield is total rent divided by price; net yield deducts all costs. NZ property investors must also navigate the Bright-Line test (capital gains on sales within the hold period) and evolving interest deductibility rules that significantly affect after-tax returns.

How it works

Gross yield vs net yield

Gross yield (%) = (Annual rent / Property price) x 100

Net yield (%) = ((Annual rent - Total annual costs) / Property price) x 100

Annual costs include: property management (typically 7-10% of rent), insurance, rates (council property tax), maintenance, body corporate levies (for apartments), and vacancy allowance.

NZ-specific tax rules

Bright-Line test: Residential investment property sold within 2 years of purchase (from 1 July 2024) is taxed on the capital gain at the seller’s marginal income tax rate. The new-build exemption (previously 5-year bright-line) has been reduced to the standard 2-year period.

Interest deductibility: For residential investment properties acquired on or after 27 March 2021, mortgage interest was fully non-deductible from the 2025-26 income year. However, from 1 April 2024, interest deductibility is being phased back in:

• 2024-25: 80% deductible
• 2025-26: 100% deductible

This restoration significantly improves net yields for leveraged investors.

New builds: Properties with a Code Compliance Certificate issued on or after 27 March 2020 can fully deduct interest for 20 years from the CCC date.

Typical NZ yields

NZ gross rental yields generally range from 3.5% to 6.5%, depending on location:

Worked example

NZ$770,000 property in Wellington, NZ$650/week rent, 35% deposit (investor LVR):

1. Annual rent: NZ$650 x 52 = NZ$33,800
2. Gross yield: (NZ$33,800 / NZ$770,000) x 100 = 4.39%
3. Property management (8%): NZ$33,800 x 0.08 = NZ$2,704
4. Insurance: NZ$2,200
5. Council rates: NZ$3,500
6. Maintenance: NZ$2,000
7. Vacancy (2 weeks): (2/52) x NZ$33,800 = NZ$1,300
8. Total annual costs: NZ$11,704
9. Net rental income: NZ$33,800 - NZ$11,704 = NZ$22,096
10. Net yield: (NZ$22,096 / NZ$770,000) x 100 = 2.87%

With full interest deductibility restored (2025-26), mortgage interest on a NZ$500,500 loan at 5.40% = NZ$27,027 is fully deductible against rental income for tax purposes.

Key differences from other markets

• Bright-Line test functions as a targeted capital gains tax on property — NZ has no general capital gains tax, unlike Australia (CGT with 50% discount after 12 months) or the UK (CGT at 18%/24%).
• Interest deductibility phase-back is unique to NZ — the rules changed three times between 2021 and 2024, creating significant complexity. The UK removed mortgage interest relief entirely for individual landlords (replaced with a 20% tax credit), while Australia allows full interest deductibility with no restrictions.
