Noise is one of the most common complaints in apartment living, and in New Zealand, the rules around it are more layered than many buyers realise. The Building Code sets a minimum standard for sound insulation between adjoining units, but that standard — outlined in Clause G6 — only covers airborne and impact noise between properties that share a wall, floor, or ceiling. It doesn’t guarantee a quiet home. What I’ve noticed over time is that buyers often assume “meets code” means “soundproof,” and that misunderstanding can lead to real frustration after settlement. Here’s what you actually need to know.
The rules that apply to your apartment depend on where it’s built, when it was built, and what’s around it. District plans can add extra requirements — for example, if the building sits near a main road or industrial zone, the council may demand higher external sound insulation. And the body corporate’s role in managing noise complaints is often overlooked until a problem arises. Understanding these layers before you buy is the difference between a home that works and one that doesn’t.
What the Building Code Actually Requires for Sound Insulation
The key thing to understand is that Clause G6 is a minimum. It’s not a guarantee of quiet. A building that meets the Code can still let through enough noise to bother light sleepers or people working from home. What I’d do in your position is ask the seller or developer for the specific acoustic test results — not just a statement that the building “complies.” Those results tell you the actual decibel reduction, and they vary widely even among compliant buildings.
How Noise Affects Apartment Living — and What the Law Says About It
Under the Resource Management Act (RMA), no one is allowed to make “excessive” noise from their property. But what counts as excessive depends on context. A loud party at 2am in a residential suburb is treated differently from the same noise in a central city entertainment district. The council’s noise control officers make that call based on guidelines in the district plan, and they can issue verbal or written directions to reduce the noise immediately.
If the noise continues or repeats within eight days, a police officer can seize the instrument, appliance, or vehicle causing it. That’s a serious step, and it’s not common — but it shows the law does have teeth. For barking dogs, the RMA doesn’t apply; instead, the Dog Control Act 1996 gives the council’s dog control officer the power to issue notices or remove the dog.
One thing that often catches buyers off guard is that some noise sources are exempt from the RMA’s excessive noise provisions. Cars, trucks, and planes on public roads or in flight paths are handled by other agencies — the police traffic branch for vehicles, and the council through district plan controls for airports. If you’re looking at an apartment near a major road or flight path, the Building Code’s external noise requirements in the district plan are what matter, not the RMA’s general rules. I’ve seen buyers assume they can complain about traffic noise after moving in, only to find there’s no legal avenue for it.
Where Apartment Buyers Misjudge Noise Regulations
Assuming “meets code” means soundproof
This is the most common mistake. Clause G6 compliance means the building passed a minimum test — not that you won’t hear your neighbour’s TV. The difference between a compliant building and a well-soundproofed one can be substantial. Ask for the specific acoustic rating (like STC or IIC values) rather than a simple pass/fail statement.
Ignoring the district plan’s external noise rules
If the apartment is in a noisy area — near a motorway, railway, airport, or industrial zone — the council may have extra insulation requirements in the district plan. These are separate from the Building Code and can affect window glazing, wall construction, and ventilation. Not checking these before buying can mean living with noise you can’t fix.
Overlooking the body corporate’s noise rules
Many apartment buildings have their own noise bylaws in the body corporate rules. These can be stricter than the RMA — for example, limiting noise after 10pm or banning certain activities. But they’re only enforceable if they’re properly registered and applied consistently. Buyers often don’t read these rules until a problem arises.
Thinking the council will solve everything
Noise control officers have limited resources and work within guidelines that vary by zone. What’s unreasonable in a suburb may be acceptable in a city centre. If the council can’t or won’t act, your next option is the Environment Court — but that costs around $285 to apply, plus roughly $800 in hearing fees. That’s a significant barrier for most people.

How to Assess Noise Before You Buy an Apartment
Review the acoustic report and building consent documents
For any apartment built after the current Building Code came into effect, the developer should have an acoustic report showing compliance with Clause G6. Ask for it. Look for the specific test results — not just a statement of compliance. If the report isn’t available, that’s a red flag. You can also check the building consent documents lodged with the council, which should reference the acoustic design.
Visit at different times and days
A single visit on a Sunday afternoon won’t tell you much. Go back on a weekday evening, a Friday night, and early in the morning. Listen for traffic, neighbours, common area noise, and external sources like nearby businesses. If possible, talk to current residents about their experience. They’ll often tell you things the seller won’t.
Check the district plan for external noise requirements
Your local council’s district plan will show whether the area has specific noise controls — for example, near airports, motorways, or industrial zones. These can require higher insulation standards than the Building Code. If the apartment is in a designated “noise-sensitive” area, the developer may have had to meet stricter rules. If it’s not, you’re relying on the minimum.
Read the body corporate rules on noise
The body corporate rules often include noise bylaws. These can be more restrictive than the RMA — for example, banning noise after 10pm or requiring carpets in certain rooms. Make sure the rules are registered with the Land Information New Zealand (LINZ) and are being enforced consistently. A rule that’s on paper but never applied is worth little.
Consider a pre-purchase inspection with acoustic testing
For a serious purchase, you can hire a consultant to do basic acoustic testing. This isn’t common, but it’s an option if you’re particularly sensitive to noise or if the apartment is in a potentially noisy location. The cost is usually a few hundred dollars — small compared to the cost of living somewhere you can’t sleep.

Know What You’re Buying Into Before You Sign
Noise regulations in New Zealand apartments are a patchwork of Building Code minimums, council district plans, and body corporate rules. None of them guarantee a quiet home on their own. The most practical step you can take is to do your own investigation before purchase — read the acoustic report, visit at different times, check the district plan, and review the body corporate rules.
