🏠 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.

                Key Point: First home buyers need a 20% deposit to avoid Lenders Mortgage Insurance (LMI), but can borrow with as little as 10% deposit (5% for new builds or through the Kainga Ora First Home Loan). You can boost your deposit with the KiwiSaver first home withdrawal (withdraw most of your balance, leaving a minimum $1,000). Note: the First Home Grant (formerly the KiwiSaver HomeStart Grant) closed to new applications on 22 May 2024 and is no longer available. Total costs include deposit, legal fees ($1,500-$3,000), building reports ($500-$800), LIM ($300), moving costs, and initial setup. Budget $5,000-$10,000 on top of deposit.
            

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):

Minimum 10% deposit (Low Equity Loan - LMI applies)

Recommended 20% deposit (No LMI, better rates)

Example: $600K home needs $120K for 20% deposit

New Build Deposit:

Minimum 5% deposit for new builds

Government supports new build lending

Example: $700K new build needs $35K for 5%

Loan to Value Ratio (LVR)

LVR is the percentage you borrow vs property value:

LVR = Loan Amount ÷ Property Value × 100

Example: Borrow $480K on $600K home

LVR = $480,000 ÷ $600,000 × 100 = 80%

20% deposit = 80% LVR

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

⚠️ Lenders Mortgage Insurance (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.

KiwiSaver Withdrawal

Can withdraw KiwiSaver savings (not employer/government contributions) for first home:

Must leave $1,000 in KiwiSaver account

Can withdraw all member contributions + returns

Example: $45,000 in KiwiSaver, withdraw $44,000

Borrowing Capacity

How much can you borrow? Banks assess:

Income Assessment:

Combined household income

Job stability (probation periods matter)

Other income sources (rental, side business)

Debt-to-Income (DTI) Ratio:

Total debt ÷ Annual income < 6x (NZ guidance)

Example: $100K income → max $600K total debt

Includes car loans, student loans, credit cards

Servicing Calculation:

Banks stress-test at higher rates:

Current rate: 6.5%

Test rate: 8.5-9.0% (stress test)

Must afford repayments at test rate

Ensures buffer if rates rise

Ongoing Property Costs

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

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!

💡 First Home Buyer Tips

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

🌍 Real-World First Home Buyer Stories

Young Couple - Auckland Apartment

Alex & Jordan, both 28, combined income $140,000

Their Situation:

Target: 2-bed apartment, $650,000

Saved: $55,000 cash

KiwiSaver: $35,000 (Alex), $32,000 (Jordan)

Both in KiwiSaver 5+ years

The Numbers:

20% deposit needed: $130,000

KiwiSaver withdrawn: $66,000 ($33K each)

Cash used: $55,000

Subtotal available: $121,000

Shortfall to save: $9,000 deposit + $8,000 costs = $17,000

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%

Single Buyer - Wellington Townhouse

Priya, 32, income $95,000

Challenge:

Single income = lower borrowing capacity

Bank approved: $500,000 loan max

With 20% deposit: $625,000 max purchase

Solution: New Build:

New build townhouse: $680,000

5% deposit allowed: $34,000

Loan: $646,000 (95% LVR)

Bank approved due to new build exception

Funding:

Savings: $15,000

KiwiSaver: $48,000 (withdraw $47,000)

Total: $62,000

Deposit: $34,000

Costs: $9,000

Remaining: $19,000 (emergency fund + furniture)

Stretched Budget - Learned Hard Way

Mike & Sarah, maxed out borrowing capacity

The Mistake:

Combined income: $120,000

Bank approved: $650,000 loan

Purchased: $800,000 home (max budget)

Monthly mortgage: $4,108

Left no buffer for costs

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.
