A $900,000 property sits around the Wellington median and the upper range for Hamilton and Christchurch. Here is exactly what you need — income, deposit, and repayments — to buy at this price.
To buy a $900,000 home in NZ with a standard 20% deposit ($180,000), you need a gross annual income of at least $120,000 under DTI 6×. Monthly repayments on the $720,000 loan at 5.50% over 30 years are approximately $4,088/month. Two incomes averaging $60,000 each will meet the DTI threshold — but the bank's serviceability stress test may require more depending on expenses and existing debt.

Minimum Income Required
With a 20% deposit ($180,000):
- Loan amount: $720,000
- Minimum gross income: $720,000 ÷ 6 = $120,000 per year
With a 10% deposit ($90,000):
- Loan amount: $810,000
- Minimum gross income: $810,000 ÷ 6 = $135,000 per year
These are DTI floors only. Student loans, car loans, and credit card limits all reduce borrowing capacity.

Frequently Asked Questions
What salary do you need to buy a $900,000 house in NZ?
With a 20% deposit, a minimum gross income of $120,000 (sole or combined) under DTI 6×. The bank’s serviceability stress test at 7.5%–8.5% may require a higher effective income depending on living expenses and other debt.
Can I buy a $900,000 house with a 5% deposit in NZ?
Potentially — through the First Home Loan scheme, which allows 5% deposit for eligible first home buyers. However, the $900,000 price point exceeds the First Home Loan price caps in most regions. Check the Kāinga Ora website for current regional caps.
How much are the monthly repayments on a $900,000 house in NZ?
With a 20% deposit ($180k) and a $720,000 loan at 5.50%, approximately $4,088/month over 30 years, or $4,432/month over 25 years.
How long does it take to save a $180,000 deposit in NZ?
Saving $800/week takes approximately 4.3 years to reach $180,000. KiwiSaver can add $15,000–$60,000+ through a first home withdrawal, shortening this meaningfully.
Is a $900,000 home affordable in NZ on a combined household income?
At $130,000 combined gross (~$8,400/month net), a $4,088/month repayment is possible but tight. Most financial planners suggest keeping housing costs below 30–35% of net income. That benchmark suggests a target repayment of $2,520–$2,940/month on $8,400/month net — meaning $900k is a stretch. A larger deposit or higher income makes it more comfortable.
