Legal and Due Diligence Costs When Buying a House in New Zealand

Why these costs exist

Buying a house in New Zealand involves a series of professional services and reports that protect you as a buyer. Some of these are legally required (you need a solicitor to settle a property purchase). Others are strongly recommended to avoid buying a property with hidden problems. Skipping them to save money is rarely wise — the cost of discovering a defect after settlement is far higher than the cost of the due diligence that would have found it beforehand.

Solicitor / conveyancer fees

A property solicitor or conveyancer handles the legal work involved in transferring ownership to you: reviewing the sale and purchase agreement, conducting title searches, liaising with your bank, managing the settlement funds and registering the change of title at Land Information New Zealand (LINZ). This is not optional — you legally need a solicitor for a property purchase.

Typical conveyancing fees for a standard residential purchase in NZ range from $1,500 to $2,500, including disbursements (the direct costs the solicitor passes on — title searches, LINZ registration fees and so on). Complex transactions — properties with unusual easements, unit title issues, leasehold land, or multiple conditions on the agreement — can push costs higher. Some firms charge fixed fees for straightforward purchases; others bill hourly.

It's worth getting quotes from two or three solicitors. Conveyancing is a competitive market and fees vary. The cheapest firm isn't always the best choice — look for experience with residential property transactions and clear communication, not just the lowest price. Mistakes in conveyancing can be expensive to fix.

LIM report

A LIM (Land Information Memorandum) is a report prepared by the local council listing all the information it holds about a property. This includes:

• Building consents issued (and whether they were signed off as complete)
• Drainage and stormwater connections
• Zoning (what the land is designated for under the district plan)
• Natural hazard status (flood zones, liquefaction risk, cliff risk)
• Any notices or orders issued in relation to the property (including by the council itself)
• Rates status

The LIM does not guarantee there are no problems — it only discloses what the council knows. An unconsented addition that the council doesn't know about won't appear. But a LIM will reveal whether the consents that were issued match what's on the property, which is a valuable starting point.

LIMs cost between $300 and $500, depending on the council, and typically take 5–10 working days. Urgent LIMs cost more. You need to apply directly to the relevant council — your solicitor can do this on your behalf.

Building inspection report

A pre-purchase building inspection gives you an independent assessment of the property's structural condition, cladding, roofing, plumbing, electrical, drainage and weathertightness. A qualified building inspector walks through the property and provides a written report identifying any defects, areas of concern and maintenance issues.

For an existing home, a building inspection is strongly recommended. The NZ property market has seen widespread weathertightness issues (the "leaky building" crisis that peaked in the 2000s), and unconsented additions and deferred maintenance are common. A building report can identify issues that allow you to negotiate a price reduction, request remediation or walk away if the problems are too serious.

Inspections typically cost $500–$1,000 for a standard residential property, with larger or more complex properties at the upper end or beyond. The cost reflects the inspector's experience and the thoroughness of the report — a four-page tick-box report is not the same as a detailed 30-page assessment with photos. Ask for a sample report before engaging an inspector.

New builds generally don't require a pre-purchase building inspection in the same way, as the consenting and inspection process during construction covers much of this ground. However, a builder's walk-through before accepting a new build is still worthwhile.

Registered property valuation

For most standard residential purchases, a formal registered valuation isn't required. Banks often use automated valuation models (AVMs) or desktop valuations to confirm the purchase price is reasonable. However, a full registered valuation (carried out by a registered valuer in person) may be required for:

• Properties in smaller towns or rural areas where comparable sales data is limited
• Properties with unusual features or mixed uses
• Purchases significantly above recent comparable sales
• Some leasehold or cross-lease properties

A registered valuation typically costs $700–$1,200. If you commission one independently (rather than through your bank), you'll need to check whether your lender will accept it or whether they want to commission their own.

Mortgage registration fee

When your bank registers the mortgage against the property title at LINZ, there's a registration fee. This is typically in the range of $150–$200 and is usually included in your solicitor's disbursements rather than appearing as a separate line item.

Summary of typical costs

Cost item	Typical range	Required?
Solicitor / conveyancer fees	$1,500 – $2,500	Yes
LIM report	$300 – $500	Strongly recommended
Building inspection	$500 – $1,000	Strongly recommended
Registered valuation	$700 – $1,200	Sometimes required
Mortgage registration fee	$150 – $200	Yes (via solicitor)
Typical total (existing home)	$2,500 – $5,200

The costs of properties that fall over

One thing many first home buyers don't budget for is the cost of a purchase that doesn't proceed. If you commission a building inspection or LIM on a property and then find a serious defect — or the vendor doesn't accept your offer — you've spent $800–$1,500 on reports for nothing. This is a normal part of the buying process and can happen multiple times before you successfully purchase.

Budget for at least one "failed" property's worth of due diligence costs as part of your overall buying budget. If you're competing in an auction environment without conditions, it becomes even more important to complete due diligence before the auction date, as you can't add conditions after the hammer falls.

KiwiSaver withdrawal: the timing issue

If you're using KiwiSaver for your deposit, remember that your due diligence costs still need to be in cash. The KiwiSaver withdrawal goes directly to your solicitor's trust account as part of the deposit at settlement — it's not available to pay for a building inspection three weeks earlier. Keep a cash buffer separate from your KiwiSaver for the pre-settlement due diligence costs.
