On a $70,000 gross salary in New Zealand, the RBNZ’s DTI 6x limit sets your theoretical maximum mortgage at $420,000 — assuming no other debts. Here is exactly what that means for your purchasing power, repayments, and the properties you can realistically target.
On a $70,000 gross salary with no existing debt, the DTI 6x maximum mortgage is $420,000. With a 20% deposit of $105,000, you could purchase a property up to $525,000. Monthly repayments on $420,000 at 5.50% over 30 years are approximately $2,385/month. The bank's serviceability stress test at ~7.5-8.5% may reduce this if your living expenses are high.
Your Salary in NZ Context
A $70,000 salary is close to the NZ mean and sits in roughly the 50th–55th percentile of earners. Common roles at this level include experienced tradespeople, registered nurses, junior engineers, and team leaders.
Your approximate take-home pay at $70,000 gross: around $1,054/week after PAYE income tax and ACC earner levy.
Maximum Borrowing Capacity
Under the RBNZ DTI 6x rule:
| Scenario | Amount |
|---|---|
| DTI maximum mortgage | $420,000 |
| Maximum purchase price (20% deposit) | ~$525,000 |
| 20% deposit required | $105,000 |
| Monthly repayment (5.50%, 30yr) | $2,385 |
| Weekly repayment (5.50%, 30yr) | $550 |
What reduces this? Any existing debt — student loans, car loans, credit card limits — is subtracted from your DTI capacity. A $30,000 car loan reduces your maximum mortgage by $30,000. A $10,000 credit card limit (regardless of balance) reduces it by approximately $10,000.
Repayments on $420,000 at Different Rates
| Rate | Monthly | Fortnightly | Weekly |
|---|---|---|---|
| 5.20% | $2,306 | $1,064 | $532 |
| 5.50% | $2,385 | $1,101 | $550 |
| 5.80% | $2,464 | $1,137 | $569 |
| 6.20% | $2,572 | $1,187 | $594 |
| 6.50% | $2,655 | $1,225 | $613 |
Serviceability Stress Test
The DTI 6x limit is one constraint. The bank also applies a serviceability test: can your income cover the mortgage repayment at a stress-test rate of approximately 7.5%–8.5%, after all assessed living expenses?
Stress test repayment on $420,000 at 8.0%, 30 years: approximately $3,082/month.
If your gross income is $70,000 and your take-home is ~$1,054/week (~$4,567/month), the stress test repayment of $3,082/month represents approximately 67% of your net monthly income — before other living expenses. Banks benchmark total committed expenses (including mortgage) against income; where expenses are high, the actual offer may be below the DTI maximum.
What Can You Buy on $70,000?
At $525,000, you can access Christchurch (median ~$680k for house, lower for units), many Dunedin properties, and some Hamilton options. Auckland and Wellington remain above this range for most houses.
25 vs 30 Year Term
On $420,000 at 5.50%:
- 30-year term: $2,385/month — total interest $438,497
- 25-year term: $2,579/month — total interest $353,750
- Saving with 25-year term: $84,747 in total interest
The 25-year term costs $194/month more but saves $84,747 in total interest. Worth considering if your income comfortably covers the higher payment.
