Buying your first home in New Zealand involves understanding deposits, LVR ratios, KiwiSaver HomeStart grants, borrowing capacity, and the complete purchase process. This guide walks you through every step from saving to settlement, with real NZ examples and costs.
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 |
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.
Government grant for first home buyers (not a loan, doesn't need repayment):
| Years in KiwiSaver | Existing Home | New Build |
|---|---|---|
| 3 years | $1,000 per person | $2,000 per person |
| 4 years | $2,000 per person | $4,000 per person |
| 5+ years | $5,000 per person | $10,000 per person |
Couple scenario: Both in KiwiSaver 5+ years buying new build = $20,000 grant!
Can withdraw KiwiSaver savings (not employer/government contributions) for first home:
How much can you borrow? Banks assess:
Banks stress-test at higher rates:
Budget for these annual costs:
| Cost | Annual Amount | Notes |
|---|---|---|
| Mortgage repayments | $35,000+ | Depends on loan size |
| 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 |
1. Save aggressively: Every extra $10K deposit saves $50/month in repayments
2. Get HomeStart grant: Free $5K-$10K per person
3. Buy within means: Don't max out borrowing capacity
4. Consider new builds: Lower deposit (5%), HomeStart grant doubles
5. Location matters: Balance price vs commute vs growth potential
Purchase price: $750,000
Can only save 10% deposit:
Taking advantage of 5% deposit rules:
$500,000 loan over 30 years at different rates:
| Rate | Monthly | Annual | Total Paid | Total Interest |
|---|---|---|---|---|
| 5.5% | $2,838 | $34,056 | $1,021,680 | $521,680 |
| 6.5% | $3,160 | $37,920 | $1,137,600 | $637,600 |
| 7.5% | $3,496 | $41,952 | $1,258,560 | $758,560 |
| 8.5% | $3,845 | $46,140 | $1,384,200 | $884,200 |
Key insight: 1% rate increase = $322/month or $3,864/year more!
$550,000 loan at 6.5%:
Alex & Jordan, both 28, combined income $140,000
Priya, 32, income $95,000
Mike & Sarah, maxed out borrowing capacity
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.
