You’ve found the perfect commercial space in New Zealand. The base rent looks manageable. But the real cost of leasing a commercial property often sits outside that headline number. In Auckland, office outgoings alone averaged $137 per square metre in late 2025, with a 6.8% year-on-year increase, according to a Bayleys report. That’s on top of your rent. For a 200-square-metre office, that’s an extra $27,400 a year before you’ve paid a single dollar in utilities or repairs. Here’s what you actually need to know.
These figures aren’t just numbers on a spreadsheet. They represent the gap between what you budget for and what you actually pay. Many tenants focus on the rent and overlook the operating expenses, known as outgoings, that landlords pass through. The result? A lease that looks affordable on paper but strains cash flow from month one. I’ve seen businesses sign up for spaces only to discover their total occupancy cost is 30–40% higher than they planned. Understanding these costs before you sign is the difference between a lease that works for you and one that works against you.
This guide breaks down the hidden costs in NZ commercial leases — what they are, how they’re calculated, where landlords have room to move, and what you can do to protect your bottom line. A commercial rental checklist is a good place to start, but you need to dig deeper.
What Outgoings Actually Cover and Why They Vary
Outgoings are the operating expenses of the building you’re renting. They cover everything from local authority rates and building insurance to common area cleaning, landscaping, and the building’s Warrant of Fitness (WOF). The landlord pays these bills upfront, then passes them through to tenants based on a proportionate share. That share is typically calculated using your net lettable area as a percentage of the total building, though some leases use gross floor area or a fixed percentage.
What I tend to notice is that tenants underestimate how much these costs vary between buildings. A green-certified office might have lower utility bills, but its overall outgoings can be higher due to elevated rates and premium location costs. The composition matters as much as the total. For example, utilities are the fastest-growing outgoing category, but rates remain the largest component and are largely outside anyone’s control — they’re tied to property valuations and council policy. Exploring emerging commercial rental hotspots might save you on base rent, but outgoings can eat those savings if you’re not careful.
Why These Costs Matter More Than You Think
The total occupancy cost — rent plus outgoings — is the real measure of what a lease costs you. And outgoings aren’t static. Auckland office outgoings jumped 6.8% in a single year, according to the Bayleys report. For a tenant paying $137 per square metre, that’s an extra $9.32 per square metre annually. On a 300-square-metre lease, that’s nearly $2,800 more each year without any change to your space or usage.
Consider a practical scenario. You’re looking at two industrial units. Unit A has a base rent of $180 per square metre with outgoings of $30 per square metre. Unit B has a base rent of $170 per square metre with outgoings of $40 per square metre. Unit B looks cheaper until you add them up — $210 per square metre total versus $210 per square metre. They’re identical. But Unit B’s outgoings are higher and more volatile because industrial properties tend to have unpredictable repairs and maintenance costs. Over a five-year lease, that volatility could cost you thousands more if those costs spike.
There’s also a demographic angle worth noting. Smaller businesses and startups often lack the negotiating power to push back on outgoings clauses. Larger tenants with multiple locations can demand caps and audit rights. If you’re a single-location business, you’re more likely to accept whatever the landlord puts in front of you. That’s where the real cost accumulates — not in the rent, but in the line items you didn’t question. Choosing the right warehouse space involves comparing total occupancy costs, not just rent.
Where Tenants Get Tripped Up
Capital expenditure disguised as outgoings
One of the most common issues I see is landlords passing through capital improvements as operating expenses. A new roof, an HVAC replacement, or structural upgrades are capital items — they improve the building’s value and should be the landlord’s responsibility. But some leases define outgoings broadly enough to include them. If your lease says “all costs associated with the building,” that’s a red flag. You want it to say “operating and maintenance costs only.” The distinction matters because capital expenditure can run into hundreds of thousands of dollars, and your share could be substantial.
Excessive management fees
Property management fees are a legitimate outgoing, but they need to be reasonable. Some landlords charge a percentage of total outgoings as a management fee, which creates a perverse incentive — the higher the outgoings, the higher their fee. A 10% management fee on $200,000 in outgoings is $20,000. If the landlord controls which costs are included, they have little reason to keep them low. Your lease should specify the management fee structure and ideally cap it as a fixed amount or a lower percentage.
Not checking the reconciliation
Landlords are supposed to provide annual budgets and year-end reconciliations showing what was actually spent versus what was estimated. Many tenants never look at these. If the landlord overestimated and collected more than needed, you’re owed a credit. If they underestimated, you get a bill. But without reviewing the reconciliation, you won’t know if the numbers are accurate. You have the right to question or audit outgoings expenses if they seem unclear or unreasonable. Smart tips for renting a commercial space include understanding your audit rights.
Ignoring the make-good clause
At the end of your lease, you’re typically required to reinstate the space to its original condition — this is the “make good” obligation. If you installed partitions, wiring, or custom fittings, you’ll need to remove them and repair any damage. These costs can be significant, especially for fit-outs that cost tens of thousands of dollars. Some tenants budget for fit-out but forget about de-fit. The lease should specify what “make good” means in detail, not just a vague reference to “original condition.”

How to Budget and Negotiate Your Way Through Outgoings
Request historical data before you sign
Before committing to a lease, ask the landlord for the last two to three years of outgoings statements. This gives you a baseline for what to expect. Look for trends — are costs rising faster than inflation? Are there one-off items that won’t repeat? If the landlord hesitates or says they don’t have the data, that’s a warning sign. A transparent landlord will provide this information without pushback. You can also ask for a breakdown of each category so you understand where your money is going.
Negotiate a cap on annual increases
One of the most effective protections is a cap on how much outgoings can rise each year. A typical cap might be 5% or the Consumer Price Index (CPI), whichever is lower. This doesn’t eliminate increases, but it prevents shock jumps. Without a cap, a 6.8% increase like Auckland’s office outgoings becomes your problem entirely. With a 5% cap, you limit the damage. Some landlords will resist, especially in tight markets, but it’s worth pushing for. If they won’t cap the total, try capping specific categories like management fees or maintenance.
Understand what’s included and excluded
Your lease should list every outgoing item specifically. Vague language like “all building costs” is dangerous. You want a schedule that names each item: rates, insurance, cleaning, utilities, maintenance, management fees, and so on. Equally important is what’s excluded. Capital improvements, legal costs for lease preparation, and costs related to vacant spaces should not be passed through to you. If the landlord has vacant units, their share of outgoings should be their responsibility, not spread among the remaining tenants.
Audit the reconciliation annually
Once you’re in the lease, review the year-end reconciliation every year. Compare actual spending to the budget. If there’s a significant variance — say, 10% or more — ask for an explanation. You have the right to audit the landlord’s records, though you may need to cover the cost of an independent review. This isn’t about being adversarial; it’s about making sure you’re only paying your fair share. Many tenants skip this step and end up overpaying for years without realising it. The open-plan versus private office debate is another factor that affects your total occupancy cost through layout and fit-out expenses.

Know Your Total Occupancy Cost Before You Sign
The headline rent is only half the story. Your total occupancy cost — rent plus outgoings, plus fit-out, plus make-good — is what determines whether a lease is sustainable for your business. Auckland’s outgoings are rising at 6.6–6.8% annually, and rates are the largest and least controllable component. The businesses that manage this well are the ones that ask for historical data, negotiate caps, and review reconciliations every year. They treat outgoings as a negotiable part of the lease, not a fixed cost they have to accept.
Your next step is simple: before you sign any lease, ask the landlord for three years of outgoings statements. If they can’t or won’t provide them, that tells you something about how they operate. If they do, you have the data you need to budget accurately and negotiate from a position of knowledge.
