Top Legal Considerations for NZ Commercial Property Investors | NZ Legal

Investing in commercial property in New Zealand can generate strong returns — long lease terms, commercial tenants who typically bear outgoings, and (for most investors) no capital gains tax on commercial property held long term. But commercial property investment is also legally more complex than residential investment. The due diligence required, the lease structures involved, the GST implications, and the ownership structure decision each carry real financial consequences if they are not handled correctly.

This article covers the top legal considerations that every NZ commercial property investor should understand before they commit.

1. Due Diligence — More Than a Title Search

For commercial property, due diligence goes well beyond what is standard in a residential purchase. A thorough commercial property due diligence covers:

Title and registered interests: Obtain a current Record of Title from LINZ. Review all registered interests — easements (particularly where they affect access or development), covenants (which may restrict permitted use), consent notices, and any caveats. Confirm the legal description matches what you are purchasing.

LIM report: A Land Information Memorandum from the local council provides information on zoning, rates, consents and compliance (including any outstanding notices), hazard information, and any council records relating to the property. For commercial property, outstanding building consents or enforcement notices can be deal-breakers.

Zoning and permitted use: Confirm the property is zoned for its current use under the relevant district plan and the Resource Management Act 1991. If you intend to change the use, investigate whether resource consent is required. Auckland Council’s GIS viewer and district plan are publicly accessible. Check that the tenant’s current use is a permitted activity (or has the necessary consent) — a tenant operating without resource consent creates risk for the landlord.

Building condition: Commercial buildings present risks that do not arise in residential transactions — asbestos, earthquake-prone building status, weathertightness issues, seismic strengthening obligations under the Building (Earthquake-prone Buildings) Amendment Act 2016. Commission an independent building inspection and review any engineer’s reports before going unconditional.

Lease review: Review the existing lease thoroughly. Key terms to assess include: the remaining term and any options to renew, the rent review mechanism, the permitted use clause, the outgoings and who pays them, maintenance obligations, make-good provisions, and the tenant’s right to assign or sublet.

“

The investment thesis for a commercial property is only as strong as the lease underpinning it. A long-term lease to a creditworthy tenant with favourable review mechanisms is a very different asset from a monthly tenancy with no covenant strength.

2. GST — The Transaction Traps

GST is one of the most important and most misunderstood aspects of commercial property transactions in New Zealand. Getting it wrong can mean paying 15% more (or less) than you expected.

The zero-rating rules

Under the Goods and Services Tax Act 1985, the sale of commercial property is generally subject to GST at 15%. However, where both the vendor and purchaser are GST-registered and the property is being used to make taxable supplies (i.e., commercial rental income), the transaction is typically zero-rated for GST. This means no GST is added to the purchase price — both parties must confirm their GST status in the sale and purchase agreement.

The key rule: If the purchaser is not GST-registered (or does not intend to use the property to make taxable supplies), GST at 15% applies on top of the purchase price. For a $3 million commercial building, that is an additional $450,000 — a cost that can destroy the investment’s financial model if not identified in advance.

Practical steps

• Confirm your GST registration status before agreeing to purchase price
• The sale and purchase agreement must correctly record whether the transaction is zero-rated or standard-rated
• If you are purchasing through a new entity (company, trust, or LTC), ensure the GST registration is in place before settlement
• Obtain tax advice early — a lawyer can review the GST clauses in the agreement, but a tax accountant should confirm the broader GST position

Depreciation

Commercial buildings can be depreciated for tax purposes (unlike residential buildings since 2010). The depreciation rate is 2% diminishing value or 1.5% straight-line for non-residential buildings. Depreciation provides a tax deduction against rental income, reducing the net cost of the investment. Note that depreciation is clawed back (taxed as income) on sale if the building is sold for more than its depreciated value — a factor to consider in the overall investment model.

3. Bright-Line Test and Capital Gains

New Zealand does not have a general capital gains tax. However, the bright-line test under the Income Tax Act 2007 taxes gains on the sale of “residential land” (defined by reference to zoning and use) sold within a specified period of acquisition. The current bright-line period for new builds is five years; for other residential property, it depends on when it was acquired.

Commercial property is not “residential land” for the bright-line test’s purposes — so in most cases, commercial property is not subject to bright-line tax on sale. However:

• Mixed-use buildings (e.g., commercial premises with residential apartments above) may have components that are residential land
• Land acquired or developed with the intention of sale (the “dealer” or “developer” intention rules) can be taxed on sale regardless of property type
• Subdivision and development can trigger income tax on the gain even without a bright-line period

Before purchasing commercial property with a view to future development or resale, obtain tax advice on the applicable income tax rules. The answer is almost never “no tax — it’s commercial.”

4. Ownership Structure

How you hold a commercial property affects your tax position, liability exposure, succession planning, and ability to bring in other investors or partners.

Structure	Tax treatment	Liability	Best suited for
Individual / joint ownership	Marginal rate (up to 39%)	Unlimited personal liability	Simple purchases, entry-level investors
Company (standard)	28% flat corporate rate	Limited liability	Ongoing commercial investment; multiple shareholders
Look-through company (LTC)	Tax-transparent — flows to shareholders at personal rates	Limited liability	Investors wanting tax transparency; note loss-ring-fencing rules
Family trust	Trustee rate (33%) or distribution to beneficiaries	Assets separate from personal estate	Estate planning; asset protection; multi-generational holding
Limited partnership	Tax-transparent to partners	General partner: unlimited; limited partners: limited	Joint ventures; development projects

Why structure matters before you buy

Transferring a commercial property from one structure to another after purchase triggers a disposal for tax purposes (potentially income tax or bright-line) and legal costs. It is almost always significantly cheaper to establish the right structure before the purchase completes.

Key questions to resolve with your tax adviser and lawyer before signing:

• Will the property generate losses in early years? (Relevant to LTC vs company structure)
• Do you need limited liability protection? (Rules out individual ownership)
• Are there multiple investors? (Company or limited partnership)
• Is long-term estate planning a priority? (Family trust)
• What is the investor’s marginal personal tax rate? (If high, a company’s 28% rate may be preferable)

Look-through companies and loss ring-fencing

LTCs were popular for property investment because losses could be offset against personal income. The loss-ring-fencing rules introduced in October 2019 changed this: rental losses from residential rental properties held through LTCs (and most other structures) can no longer be offset against personal income — they are ring-fenced to the rental activity.

These rules do not apply to commercial property in the same way as residential rental. But the distinction requires careful tax advice to confirm.

5. Commercial Leases — What to Review as a Landlord Investor

If the property is tenanted, the lease is the investment’s income engine. Critically review:

Remaining term and options to renew: A property with three months left on the lease and no renewal options is a vacant property risk, not a tenanted investment. Confirm the term, options, and how much notice is required.

Tenant covenant strength: Who is the tenant? Is it a major corporate, a franchise, an owner-operated business? The creditworthiness of the tenant drives the income security of the investment. Request financial information or make it a condition of purchase.

Rent and rent review mechanism: What is the current rent relative to market? What is the review mechanism (fixed, CPI, market) and when is the next review? A long lease with a hard ratchet and above-market rent is a different risk profile from a short lease with a market review pending.

Outgoings (OPEX): Under a net lease, the tenant pays outgoings. Confirm what is and is not included, and review the last actual OPEX statement to understand the true annual cost base.

Make-good obligations: At lease end, will the tenant be required to strip out their fit-out and reinstate the property? If so, the property should return to a lettable condition. If there is no make-good obligation, factor in refurbishment costs between tenancies.

6. Body Corporate (Unit Title Commercial Properties)

Commercial properties in unit title buildings — office suites, industrial units, retail units in a shopping complex — are subject to the Unit Titles Act 2010 and body corporate governance. Before purchasing:

• Obtain and review the body corporate’s financial statements and levy schedule
• Review the long-term maintenance plan — particularly for older buildings with deferred maintenance
• Check whether any special levies have been assessed or are anticipated
• Review the body corporate rules for restrictions on use, signage, or alterations

Special levies for major building works (cladding, lifts, roofing) can run to tens or hundreds of thousands of dollars per unit — a risk that must be priced into the acquisition.
