New Zealand manages noise under the Resource Management Act 1991 through district plans. Councils set daytime residential limits around 50–55 dBA and nighttime limits of 40–45 dBA (LAeq) plus a maximum LAFmax at night. Excessive noise can trigger an immediate abatement direction and equipment seizure. Workplace exposure is capped at 85 dBA over 8 hours.

Enforced by: Resource Management Act, district councils, WorkSafe NZ. These figures are typical national or widely-adopted municipal guidance for education only — your local ordinance is what actually applies, and limits often differ between residential, mixed and industrial zones.

How New Zealand's limits compare

Most developed countries converge on a similar pattern: roughly 55 dB by day and 40–45 dB at night in residential areas, protecting a night-time window for sleep. The WHO recommends keeping bedroom noise below about 40 dB (Lnight) outside, which is why nighttime limits cluster there. The table shows how New Zealand sits against others.

What to do about a noisy neighbour

The universal first step is to keep a dated log of the noise and, where possible, a rough level from a sound meter. Most authorities will not act on a single complaint but will on a documented pattern. If the noise is inside your home, reducing what reaches you can be faster than waiting on enforcement — our soundproofing guide covers what actually blocks sound.

Soundproofing & noise reduction

Mass and sealing beat foam. Acoustic panels tame echo inside a room; blocking sound between rooms needs mass-loaded vinyl, door seals and heavy curtains.
