Buying a $1,000,000 property in New Zealand requires a clear understanding of the income required under the RBNZ’s DTI rules, the deposit you need, and what your repayments will look like month to month.
To buy a $1,000,000 home in NZ with a standard 20% deposit ($200,000), you need a gross annual income of at least $133,333 under DTI 6x. Monthly repayments on the $800,000 loan at 5.50% over 30 years are approximately $4,542/month. The bank serviceability stress test at ~7.5-8.5% may set a different limit depending on your expenses and other debts.

Minimum Income Required
Under the RBNZ’s DTI threshold of 6× gross annual income, the minimum income needed to service a $1,000,000 purchase is:
With a 20% deposit ($200,000):
- Loan amount: $800,000
- Minimum gross income: $800,000 / 6 = $133,333 per year
With a 10% deposit ($100,000):
- Loan amount: $900,000
- Minimum gross income: $900,000 / 6 = $150,000 per year
These are DTI floors only. Student loans, car loans, and credit card limits all reduce borrowing capacity — meaning you may need a higher income if you carry any existing debt.
The bank’s serviceability stress test at approximately 7.5%–8.5% may be the binding constraint for some borrowers with high living expenses.

Saving the Deposit
Saving a 20% deposit of $200,000 is the biggest challenge for most first home buyers. Realistic timelines at different weekly savings rates:
| Weekly savings | Months to reach $200,000 |
|---|---|
| $300/week | 154 months (12.8 years) |
| $500/week | 92 months (7.7 years) |
| $750/week | 62 months (5.1 years) |
| $1,000/week | 46 months (3.8 years) |
KiwiSaver contributions count toward your deposit — a first home withdrawal can provide $15,000–$60,000+ depending on your balance, significantly accelerating the timeline.

Affordability at the Minimum Income
At $133,333 gross income (the DTI minimum) with a $4,542/month mortgage:
- Monthly gross income: $11,111
- Mortgage as % of gross income: 40.9%
- Adding rates (~$400/month) and insurance (~$250/month): 46.7% of gross income
At the DTI minimum, housing is expensive relative to income. A higher income or larger deposit significantly improves cashflow comfort.
