How to Save a House Deposit in New Zealand 2026
Saving a house deposit is the biggest financial challenge most New Zealanders face. With median house prices still well above $700,000 in Auckland, the deposit target can feel impossible — but the maths is workable with the right strategy.
You need a minimum 5% deposit with low-equity lending (LVR above 80%), but 20% is strongly preferred to avoid the low-equity margin charged by banks. For a $700,000 Auckland home that's $140,000. KiwiSaver first home withdrawal and shared ownership schemes can bridge part of the gap.
How Much Deposit Do You Actually Need?
The minimum (5%)
Banks can lend up to 95% of a property’s value under the Reserve Bank’s LVR (Loan-to-Value Ratio) rules — but they’re restricted in how many low-deposit loans they can write. In practice:
- Banks often require at least 10% deposit for existing homes
- New builds can sometimes be financed at 5% deposit more easily
- Low-equity lending attracts a low-equity margin (typically 0.5–1.5% added to your interest rate)
The target (20%)
A 20% deposit means:
- No low-equity margin on your mortgage rate
- Better chance of loan approval
- Lower overall mortgage cost
How much by city?

| Wellington | $700,000 | $70,000 | $140,000 |
| Christchurch | $600,000 | $60,000 | $120,000 |
| Hamilton | $640,000 | $64,000 | $128,000 |
| Dunedin | $540,000 | $54,000 | $108,000 |

KiwiSaver First Home Withdrawal
If you’ve been in KiwiSaver for at least 3 years, you can withdraw most of your balance (minus $1,000 to keep the account open) to buy your first home.
Key points:
- Eligible for: first home only (in most cases — exceptions for certain “second chance” buyers)
- Can use it for: deposit or settlement
- Employee + employer contributions included (plus earnings)
- Apply through your KiwiSaver provider — takes 10–15 working days
For a buyer who’s contributed for 10 years on an average salary, a KiwiSaver balance of $40,000–$80,000 is realistic.

What About the First Home Grant?
The Kāinga Ora First Home Grant was closed in May 2024. No new applications are being accepted. If you applied before closure you may still be processing, but new applicants cannot access this grant.
Don’t factor the First Home Grant into your savings plan — it no longer exists.
Deposit Savings Strategies
1. High-interest savings accounts
The most straightforward option. In 2026, the best NZ online savings accounts offer 4.5–5.5% p.a. (conditions apply — usually requires regular deposits or no withdrawals). Relevant banks:
- Kiwibank Notice Saver — competitive rates for 32-day notice
- ASB FastSaver / Savings Plus — bonus interest tiers
- BNZ Rapid Save — no-fee, competitive rate
- Heartland Bank online saver — typically top-tier rates
2. Term deposits
If your timeline is 2+ years, a term deposit locks in a rate. Shop around — rates vary by 0.5–1% between banks. Compare at interest.co.nz.
3. Shared ownership — First Home Partner (Kāinga Ora)
Kāinga Ora’s First Home Partner scheme allows shared ownership — they contribute equity, you pay rent on their share, and buy them out over time. Income and house price caps apply. Available for new builds only.
4. Family assistance
Gifted deposits or family guarantees (where a parent uses their home equity as security) can bridge a gap. Gifted deposits need to be disclosed to the bank and confirmed as non-repayable.
5. Help to Buy / government schemes
Check the Kāinga Ora website for current schemes — products change. As of 2026, First Home Loans (through participating lenders) are still available, requiring only 5% deposit with mortgage insurance underwritten by Kāinga Ora.
How Long Will It Take?
Assuming you can save $1,500/month net after all expenses:
| Target deposit | Time to save |
|---|---|
| $50,000 | ~2.8 years |
| $80,000 | ~4.4 years |
| $100,000 | ~5.6 years |
| $140,000 | ~7.8 years |
| $190,000 | ~10.6 years |
Excludes investment returns. A 5% return on savings materially shortens these timelines.
Accelerate the timeline
- Increase savings rate — review your budget and cut recurring costs
- Boost income — a pay rise, side income, or overtime has compounding effect on timeline
- Reduce rent costs — flatting, living with family, or relocating to a lower-cost area
- KiwiSaver at 3% minimum — at minimum, keep contributing to build the withdrawal balance
Common Mistakes to Avoid
- Saving in a regular bank account at 0.1% when savings accounts offer 5%
- Counting on the First Home Grant — it’s closed
- Underestimating total purchase costs — add legal fees ($1,500–$2,500), building inspection ($500–$800), LIM report ($250–$400), valuation ($600–$1,000), and moving costs
- Treating KiwiSaver as emergency fund — it’s not accessible until first home or 65
- Buying the maximum the bank will lend — leave a buffer
Your Next Steps
- Calculate your actual target deposit using current prices in your target area (CoreLogic, OneRoof, TradeMe Property)
- Check your KiwiSaver balance and eligible withdrawal amount through your provider
- Open or optimise a high-interest savings account and automate deposits on pay day
- Check current Kāinga Ora First Home Loan eligibility at kaingaora.govt.nz
- Get a mortgage pre-approval to understand what a bank will lend you
