How Much Does It Cost to Install a Heat Pump in New Zealand?
Quick answer: $2,000 to $7,500 for a standard single-room unit, $8,000 to $15,000+ for larger or ducted systems. But that range is pretty wide because your specific setup could push it either direction. Let’s break this down a bit further.
Single Room Unit (Most Common)
If you want to heat one room or a small open-plan area, you’re looking at roughly $2,000 to $4,500 fully installed (the unit itself plus labor). Sometimes you see it cheaper, sometimes more expensive. It entirely depends on whether it’s a straightforward “back to back” installation (outdoor unit goes on the wall outside your room, pipes come straight through) or whether it’s a bit more complicated.
A simple “back to back” installation is at a $2,000-ish price. If your installer has to run pipes around corners, up through the ceiling, or deal with difficult wall access, add another $500-$1,500.
In Auckland, most basic single-room installations are running $3,000 to $4,000 all-in. You could be billed less in provincial areas, with some extra tacked on if the installer ran into some complications during the process.

Multi-Room System
Got three bedrooms and a lounge you want climate controlled? A multi-room heat pump is the perfect solution – with one outdoor unit piped to multiple indoor units, you can control the temperature throughout the house with a rather slim HVAC system. You’re looking at anywhere from $4,000 to $7,000, depending on how many rooms and how spread out your house is.
The more indoor units (“heads”) you want to install in the house, the more copper piping, more electrical work, and more installation labor cost will show up on the bill. So, three rooms could be $5,500, five rooms might be $7,000, and so on.
Ducted System (Whole House)
A whole-house ducted system can heat your entire home via a ductwork system. $8,000 to $15,000 is the normal range for such a system. Could be more if you’re building new ductwork from scratch through an older house.
Here’s the thing: if your house already has ductwork (from an old central heating system), installation’s cheaper because your installer can just use the ducts that are already there. But if they need to run new ductwork through walls and ceilings, the costs will jump dramatically. Be prepared to be quoted a few thousands on electrical, too, since these systems are complex electrically and require proper balancing.

What’s Actually Included in That Price?
You need to ask your installer, but typically:
The unit itself (outdoor and indoor components). Labor for installation—physically mounting the unit, running pipes, electrical connections, testing. Materials—copper piping, electrical wire, brackets, thermostatic stuff. Certification once it’s done.
What’s often NOT included: consent from your landlord (if renting), any structural modifications (like drilling large holes), extra refrigerant if the installer’s bad at their job, warranty cover beyond standard. Ask specifically.
What Changes the Price?
- Brand matters a bit. Mitsubishi costs slightly more than Panasonic. Daikin’s somewhere in the middle. We’re talking $300-$800 difference on the equipment cost. Installation cost is usually the same regardless.
- Size matters. A 2.5kW unit for a small bedroom is cheaper than a 7kW unit for your whole open-plan. Labor to install them is similar, but the equipment cost scales.
- Installation complexity. Back to back? Cheap. Running pipes up three stories? Expensive. Through solid concrete? Expensive. Around obstacles? More expensive!
- Location matters. Urban areas like Auckland have more competition so sometimes pricing is tighter. Rural areas might have fewer installers and higher travel costs.
- Electrical work. Some installations need a dedicated circuit from your switchboard (which is right). Some need upgrading. This can be an extra $500-$1,000 if your board’s old.

Those numbers include equipment and labor.
Frequently Asked Questions (FAQs)
Why is there such a big price difference between installers – is the cheapest quote always the best deal?
Not necessarily! A quote that’s significantly lower than others might mean the installer is cutting corners – poor brazing on copper connections, rushing electrical work, or skipping thorough system testing. You often get what you pay for with HVAC work.
Can I install a heat pump myself to save on labor costs?
No. Heat pump installation requires refrigeration qualifications, electrical licensing, and proper system commissioning. DIY attempts typically fail within a year or two, and you’ll void the warranty. The labor cost upfront is far cheaper than emergency repairs or replacement later. Always use a licensed, qualified installer.
If I already have old ductwork from a previous heating system, will my installation cost less?
Yes, potentially significant savings. If your existing ducts are usable and compatible, your installer can adapt them for the new heat pump system rather than running new ductwork from scratch. This saves thousands on materials and labor. Discuss your existing ductwork with your installer during the quote phase – it could make a real difference to the final price.
Do I need to pay for building consent, or is that included in the installation cost?
Building consent isn’t typically included in the installer’s quote – that’s usually your responsibility or your landlord’s (if renting). Most standard single-room and multi-room installations don’t require consent, but larger ducted systems might. Ask your installer whether consent is needed for your specific project and whether they can handle it for you.
What happens if the installer finds problems during installation – will that cost extra?
Possibly. Hidden issues (like inadequate electrical capacity, structural complications, or existing damage) discovered during installation may require additional work and cost. That’s why it’s important to get a detailed quote breakdown upfront and discuss what could go wrong. A good installer will communicate these issues before they become expensive surprises.
The Bottom Line
Installation cost in New Zealand isn’t insane. You’re paying for the unit, the labor to do it properly, and materials. The wide range exists because every house is different.
