Most people buying a home in New Zealand focus on the deposit and the mortgage. That makes sense — those are the big numbers. But the median house price sits around $800,000 nationally, and in Auckland it’s closer to $1 million. On a $700,000 purchase, transaction costs alone can run between $5,600 and $12,600 before you even set foot inside. That’s before council rates, insurance, or maintenance.

New Zealand is one of the few countries that doesn’t charge stamp duty or a property transfer tax. That keeps the upfront bite lower than in Australia or the UK. But what replaces it is a spread of smaller costs — legal fees, reports, insurance setup, moving — that together land harder than most buyers expect. The difference between what you think you’ll pay and what you actually pay can be several thousand dollars. Here’s what you actually need to know.
Key Takeaways and What “Due Diligence” Actually Means
Most of the costs that trip up first-home buyers aren’t the mortgage — they’re the layers of fees, reports, and adjustments that sit around it. The term you’ll hear for checking these before you buy is due diligence.
What I tend to notice is that buyers who treat due diligence as a box-ticking exercise rather than a genuine investigation end up with the biggest surprises. The difference between a $500 inspection and a $2,000 specialist report can be the difference between buying a sound home and inheriting a leaky building.
What the Upfront Fees Actually Add Up To
Let’s walk through the real numbers. On a $700,000 home, the deposit might be $140,000 at 20%. But the cash you need before settlement includes a stack of other items. The table below shows the typical range for each cost based on current market data.

| Cost Category | Typical Range | Notes |
|---|---|---|
| Conveyancing and legal fees | $1,400–$3,500 | Includes LINZ lodgement and AML checks |
| Building inspection | $400–$1,200 | Rushed for auction purchases; must be done before auction day |
| LIM report | $150–$450 | Takes 5–10 working days; urgent processing costs more |
| Registered valuation | $700–$1,500 | Required by banks for high-LVR loans or unusual properties |
| Home insurance setup | $1,500–$4,000/year | Must be in place before settlement; lender requirement |
| Moving costs | $1,000–$5,000 | Local moves cheaper; inter-city moves cost more |
| Mortgage registration fee | ~$200 | One-off fee charged by the bank |
Add those up and you’re looking at $5,000 to $15,000 on top of your deposit. The wide range reflects transaction complexity — a standard standalone house with a clean title is at the low end; a cross-lease or unit title with trust structures pushes higher.
One cost that doesn’t show up on any pre-purchase checklist is settlement day adjustments. Council rates and body corporate levies that the vendor has already paid need to be reimbursed at settlement. That can add several hundred to a few thousand dollars depending on timing. Your lawyer handles the calculation, but you need cash ready for it.
Where First-Home Buyers Often Misjudge the Numbers
Underestimating the cost of due diligence reports
A building inspection at $500 and a LIM report at $300 feel like optional extras when you’re already stretching for the deposit. But skipping them — or rushing them — is the most common source of post-settlement regret. For auction purchases, all due diligence must be completed before auction day because the bid is unconditional. If you win the auction and later discover unconsented work, weather-tightness issues, or a leaky building, you own those problems. A follow-up specialist report for weather-tightness or asbestos can cost $500 to $2,000 each, but that’s still cheaper than inheriting a $50,000 repair.
Ignoring body corporate fees on apartments and townhouses
Body corporate levies range from $3,000 to $15,000 or more annually depending on the building’s age, amenities, and maintenance plan. That’s on top of council rates and insurance. Buyers focused on the purchase price sometimes overlook these until the first invoice arrives. A newer building with a pool, lift, and gym will have higher fees than a walk-up block with no common areas. Ask for the body corporate’s long-term maintenance plan and sinking fund balance before you commit.
Forgetting that insurance isn’t guaranteed
Older homes, leaky buildings, and properties in high-risk zones (flood, earthquake, coastal erosion) can be difficult or expensive to insure. Some insurers won’t cover them at all. Banks require home insurance before settlement, so if you can’t get a policy, you can’t settle. A property that looks affordable on paper may become unviable if the insurance premium is $4,000 instead of $2,000 — or if no insurer will touch it. Check insurability early, ideally before you make an offer.
Not budgeting for the first-year cash drain
Immediate maintenance, new appliances, lock changes, garden tools, and utility connections can easily eat $5,000 to $10,000 in the first six months. The research suggests keeping a cash buffer of at least three months of total housing costs — mortgage, rates, insurance, and maintenance combined. For a $700,000 home with a $500,000 mortgage at 5%, that buffer is roughly $10,000 to $12,000. Most buyers don’t have it, and that’s where credit card debt starts.
Building a Realistic Budget Around the Full Picture
Step 1: Know your numbers before you look at properties
Start with the KiwiSaver First Home Withdrawal if you’re eligible — you need at least three years of membership and must leave at least $1,000 in the account. Submit the withdrawal application as soon as your offer goes unconditional to avoid settlement delays. For the Kāinga Ora First Home Loan, you can buy with a 5% deposit, but you’ll pay a 1.2% Lenders’ Mortgage Insurance premium rolled into the loan. On a $650,000 purchase, that’s $7,410 added to the debt. Work out what your monthly repayment looks like at current rates and at rates 1% to 2% higher before you decide how much to borrow.
Step 2: Order reports in the right order
Get the LIM report first — it takes 5 to 10 working days and reveals building consents, code compliance certificates, resource consent conditions, outstanding rates, and known hazards. If the LIM shows unconsented work, you can decide whether to proceed before you spend money on a building inspection. The building inspection comes next; it should cover structural integrity, weather-tightness, plumbing, electrical, and drainage. If issues show up, a specialist report (weather-tightness, asbestos, structural) is your next step. A real estate lawyer can review the reports and advise on your options before you go unconditional.
Step 3: Factor in the ongoing costs from day one
Council rates in Auckland run $2,000 to $4,000 annually. Home and contents insurance for a standard three-bedroom home in Auckland is $1,500 to $3,000 per year. Body corporate fees add $3,000 to $15,000. Maintenance at 1% of property value is $7,000 on a $700,000 home. That’s $13,500 to $29,000 per year on top of mortgage repayments — or $1,125 to $2,400 per month. If your mortgage payment is $3,355 per month (on a $650,000 loan at 5%), the total monthly housing cost is $4,480 to $5,755. That’s the number that matters for your budget.
What’s changing: insurance and regulatory shifts
Insurance costs are rising as climate risks become clearer. Properties in flood-prone or coastal erosion zones are seeing higher premiums or coverage exclusions. The Overseas Investment Office (OIO) compliance process for non-citizen or non-resident buyers can add thousands in legal costs. For anyone buying a cross-lease or unit title property, upcoming leasehold and strata reform proposals could affect resale value and ongoing costs. These aren’t reasons to avoid buying — but they’re reasons to factor in a margin for change.

The One Number That Changes Everything
If you only track one figure beyond the purchase price, make it the total monthly housing cost — mortgage repayment plus council rates, insurance, maintenance, and body corporate fees. That’s the number that determines whether homeownership feels manageable or becomes a strain. The research shows that most buyers underestimate ongoing costs by 20% to 30% in the first year. A realistic budget, a cash buffer, and a lawyer who reviews your reports before you go unconditional are the three things that separate a smooth purchase from a stressful one.
