First Home Buyer Guide - NZ Property Purchase Calculator
๐ First Home Buyer Guide - New Zealand
Buying your first home in New Zealand involves understanding deposits, LVR ratios, the KiwiSaver first home withdrawal, the Kainga Ora First Home Loan, borrowing capacity, and the complete purchase process. This guide walks you through every step from saving to settlement, with real NZ examples and costs.
The Complete Cost Breakdown
Example: Purchasing a $650,000 home
| Cost Item | Amount | Notes |
|---|---|---|
| Purchase price | $650,000 | Agreed sale price |
| Deposit (20%) | $130,000 | Your savings + KiwiSaver |
| Mortgage amount | $520,000 | What you borrow |
| Legal/conveyancing | $2,000 | Lawyer fees |
| Building report | $650 | Pre-purchase inspection |
| LIM report | $300 | Council property info |
| Valuation | $800 | Bank requirement |
| Moving costs | $1,500 | Truck/movers |
| Initial setup | $3,000 | Appliances, furniture |
| Total cash needed | $138,250 | Deposit + costs |
Deposit Requirements
Standard Deposit (Existing Homes):
New Build Deposit:
Loan to Value Ratio (LVR)
LVR is the percentage you borrow vs property value:
| LVR Level | Deposit | Implications |
|---|---|---|
| 80% LVR | 20% | Standard lending, best rates, no LMI |
| 85% LVR | 15% | Low equity, LMI applies (+0.5-0.75% rate) |
| 90% LVR | 10% | Low equity, higher LMI (+0.75-1.00%) |
| 95% LVR | 5% | New builds only, high LMI |
LVR over 80% = LMI applies
LMI protects the bank (not you) if you default. Adds 0.5-1.0% to your interest rate annually until LVR drops below 80%. On $500K loan, LMI costs extra $2,500-$5,000/year. Pay down to 80% LVR quickly to remove LMI premium.
First Home Grant (formerly KiwiSaver HomeStart Grant) - discontinued
The First Home Grant, previously known as the KiwiSaver HomeStart Grant, closed to new applications on 22 May 2024 as part of Budget 2024. It is no longer available, so you cannot count it towards your deposit.
For context, it used to pay $1,000 for each year of KiwiSaver membership, up to $5,000 per person for an existing home or $10,000 per person for a new build. A couple could previously receive up to $10,000 (existing home) or up to $20,000 (new build). That option has now ended.
What remains available: the KiwiSaver first home withdrawal (covered next) and the Kainga Ora First Home Loan, which lets eligible buyers purchase with as little as a 5% deposit.

| Rates (council tax) | $2,500-$4,500 | Varies by location |
| Insurance | $1,200-$2,000 | House + contents |
| Maintenance | $3,000-$6,000 | 1% of property value/year |
| Body corp (if applicable) | $2,000-$8,000 | Apartments/townhouses |
The Purchase Process
Step 1: Get Pre-Approved (4-6 weeks before house hunting)
- Approach multiple banks for pre-approval
- Provide income proof, deposit evidence, ID
- Get approved amount in writing
- Pre-approval typically lasts 90 days
Step 2: Find Your Property (2-6 months)
- Attend open homes
- Research suburb prices, schools, transport
- Check property history (homes.co.nz, QV)
- Don't rush - average search takes 3-4 months
Step 3: Make an Offer (1-2 weeks)
- Submit offer through agent or directly
- Include conditions: finance, building report, LIM
- Typical condition period: 10-15 working days
- Negotiate price and terms
Step 4: Due Diligence (10-15 days)
- Order LIM from council ($300, 10 working days)
- Book building inspection ($500-$800)
- Confirm finance with bank
- Review all reports carefully
- Renegotiate or withdraw if issues found
Step 5: Go Unconditional (Day 1 after conditions met)
- Remove all conditions once satisfied
- Pay deposit (usually 10% of purchase price)
- Deposit held in trust until settlement
- Sale becomes binding
Step 6: Settlement (20-30 days after unconditional)
- Bank pays balance to vendor's lawyer
- You pay remaining costs to your lawyer
- Keys collected on settlement day
- Property officially yours!
1. Save aggressively: Every extra $10K deposit saves $50/month in repayments
2. Use your KiwiSaver: Withdraw most of your balance (leaving a minimum $1,000) towards your deposit
3. Buy within means: Don't max out borrowing capacity
4. Consider new builds: Lower deposit (5%), and the Kainga Ora First Home Loan can also help with a 5% deposit
5. Location matters: Balance price vs commute vs growth potential

๐ Real-World First Home Buyer Stories
Alex & Jordan, both 28, combined income $140,000
Their Situation:
The Numbers:
With the First Home Grant no longer available, the couple needed to save a further $17,000 before they could complete this purchase.
Outcome:
- Purchased apartment
- Mortgage: $520,000 at 6.5%
- Monthly: $3,287 + $450 body corp
- Left $1,000 in KiwiSaver for both
- Restarted KiwiSaver contributions at 3%
Priya, 32, income $95,000
Challenge:
Solution: New Build:
Funding:
Mike & Sarah, maxed out borrowing capacity
The Mistake:
What Happened:
- Hot water cylinder failed: $2,500
- Roof leak: $4,000
- Rates bill: $3,800/year (didn't budget)
- Had to use credit cards
- Financially stressed within 6 months
The Lesson:
Don't borrow maximum approved amount. Leave 15-20% buffer for unexpected costs and rate increases. Better to buy below budget than stretch too far.

Benefits:
- Strong negotiating position (large deposit)
