Buying a $1,500,000 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 $1,500,000 home in NZ with a standard 20% deposit ($300,000), you need a gross annual income of at least $200,000 under DTI 6x. Monthly repayments on the $1,200,000 loan at 5.50% over 30 years are approximately $6,813/month. The bank serviceability stress test at ~7.5-8.5% may set a different limit depending on your expenses and other debts.
The Numbers at a Glance
| 20% deposit | 10% deposit | |
|---|---|---|
| Deposit required | $300,000 | $150,000 |
| Loan amount | $1,200,000 | $1,350,000 |
| Min gross income (DTI 6x) | $200,000 | $225,000 |
| Monthly repayment (5.50%, 30yr) | $6,813 | $7,665 |
| Weekly repayment (5.50%, 30yr) | $1,572 | $1,769 |
Note: The First Home Loan (Kāinga Ora) price cap in Auckland is currently $875,000–$925,000 for existing homes. At $1,500,000, the First Home Loan does not apply (and the First Home Grant closed in May 2024) — standard 20% deposit and bank lending criteria apply.
Minimum Income Required
Under the RBNZ’s DTI threshold of 6× gross annual income, the minimum income needed to service a $1,500,000 purchase is:
With a 20% deposit ($300,000):
- Loan amount: $1,200,000
- Minimum gross income: $1,200,000 / 6 = $200,000 per year
With a 10% deposit ($150,000):
- Loan amount: $1,350,000
- Minimum gross income: $1,350,000 / 6 = $225,000 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 $300,000 is the biggest challenge for most first home buyers. Realistic timelines at different weekly savings rates:
| Weekly savings | Months to reach $300,000 |
|---|---|
| $300/week | 231 months (19.2 years) |
| $500/week | 138 months (11.5 years) |
| $750/week | 92 months (7.7 years) |
| $1,000/week | 69 months (5.8 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.

At $1.5m you’re buying in the top tier of the Auckland market, accessing premium Wellington properties, and acquiring high-value lifestyle or acreage properties elsewhere in NZ.
Affordability at the Minimum Income
At $200,000 gross income (the DTI minimum) with a $6,813/month mortgage:
- Monthly gross income: $16,667
- Mortgage as % of gross income: 40.9%
- Adding rates (~$400/month) and insurance (~$250/month): 44.8% of gross income
At the DTI minimum, housing is expensive relative to income. A higher income or larger deposit significantly improves cashflow comfort.
