Heat Pump Boundary Rules and Consent NZ

On the North Shore, sections are narrow and neighbours are close. Most people do not realise a heat pump install is not just about the indoor unit. It is about the noise at the fence line. Here is exactly what the Auckland Unitary Plan says and how we keep you compliant.

What Do You Actually Need?

Most installs are straightforward. Here is the full picture.

Situation
Requirement
The Craig Standard
Standard high-wall install
No consent required
Craig provides a Certificate of Compliance (COC) from a registered electrician for your records on every single job.
Wall penetrations up to 300mm
No consent required
Standard pipe penetrations through external walls are permitted under the Building Act.
Outdoor unit near a boundary
Noise check required
Auckland has no minimum distance rule, but you must hit 40dB at the boundary at night. Craig measures this at every quote.
Heritage or special character zone
Overlay check
Parts of Devonport, Birkenhead and Northcote Point have extra rules about outdoor unit visibility. Craig checks AUP overlays at quote time.
Hot water heat pump (outdoor)
Building consent required
Unlike space heating heat pumps, outdoor hot water cylinders always need a building consent. Different process entirely.

The "40dB Trap"

The Auckland Unitary Plan does not care how quiet the unit is at the machine. It cares what the volume is at your neighbour's fence.

50 dB Daytime limit at neighbour's boundary
Mon–Sat 7am–10pm, Sun 9am–6pm
About the volume of a normal conversation
40 dB Night-time limit at neighbour's boundary
All other times (the hard one)
About the volume of a quiet library
8 days How long an Excessive Noise Direction now lasts
Changed from 72 hours in August 2025
Repeat breaches can mean forced relocation

Three Things Craig Does at Every Quote

1. The distance test

Craig does not just look at where the unit fits. He measures the actual distance to the boundary and checks the unit's dB rating at that distance. If it is too close for a standard unit, he recommends a quieter model: the Toshiba Shorai Edge at 20dB or the Mitsubishi AP at 18dB, before anything is ordered.

2. Acoustic barriers

Sometimes the best location for heat output is the worst location for noise. Craig can advise on acoustic covers or fence dampening to keep the unit in the right spot and the noise inside the limits. A small barrier at the right angle can drop boundary noise by 3–5dB.

3. The Certificate of Compliance: why it matters for your property value

Every install Craig does is signed off by a registered electrician with a COC. This matters beyond compliance. When you sell your house, a missing COC is a red flag on the building report. It can hold up settlement, reduce your sale price, or require costly retrospective work. Having Craig's COC means the install is 100% legal and fully documented.

Deemed Permitted Boundary Activity

If the best placement would technically infringe a boundary rule, there is a process far simpler than resource consent. Craig manages this for you.

1

Confirm the infringement

Craig confirms the proposed location breaches a boundary rule in the Auckland Unitary Plan but complies with all other rules. The infringed boundary must be private, not a road, reserve or public land.

2

Get written neighbour approval

The owner of the affected property signs a standard approval form. In most cases a brief conversation is all it takes. Craig can help frame this conversation if needed.

3

Apply to Auckland Council

Submit the application online with the signed approval and a plan showing the proposed location. This replaces a full resource consent application. Significantly faster and cheaper.

4

Council responds within 10 working days

If everything is in order, Auckland Council issues a written notice confirming the activity is permitted. Installation can then proceed. In practice, most North Shore installs never reach this step. Craig's first priority is always a fully compliant placement. See what to expect during installation once approval is confirmed.

Boundary Rules FAQ

Do I have to ask my neighbour before installing?

Legally no, as long as it is a permitted activity. But on the North Shore it is always better to be a good neighbour. Craig can provide you with the dB specs of the unit to show them it will not keep them awake. Most neighbours are fine once they see the numbers.

What is a Certificate of Compliance and do I get one?

A Certificate of Compliance (COC) is issued by a registered electrician to confirm all electrical work meets the Electricity Act requirements. Every heat pump Craig installs includes a COC. A correctly installed heat pump with a COC does not appear as unconsented work on a LIM report. An unlicensed install without one can complicate a property sale. See our heat pump installation page for full details on what every install includes, and our installation cost guide for pricing.

What if I am in a heritage zone?

If you are in a special character area (like parts of Birkenhead, Devonport or Northcote Point), there may be rules about where the outdoor unit can be seen from the street. Craig checks Auckland Unitary Plan overlays for every quote. Most heritage zone installs are straightforward once you know where to put the outdoor unit.

Does a heat pump show up on my LIM report?

A standard high-wall heat pump does not. But the electrical work must be done by a registered electrician. If you go to sell and there is no record of a licensed electrician doing the work, it can hold up your settlement. Craig's COC is your proof. Keep it with your house file.

Who handles noise complaints on the North Shore?

Auckland Council's noise control team covers the North Shore. They can visit the property and measure noise levels. Call 09 301 0101 to report persistent noise. If a breach is confirmed, an Excessive Noise Direction is issued and the unit owner must remedy it. More answers in our full FAQ.
