Heat Pump Installation Cost NZ – 2026 Auckland Price Guide
Quick answer: A standard wall-mounted heat pump in New Zealand costs between $1,500 and $4,000 installed in 2026, including both the unit and professional installation — with most Auckland households paying $2,500 to $3,500 for a mid-range hi-wall unit suitable for a standard living area.

Heat pumps are the cheapest way to heat a home in New Zealand, and EECA says so in plain terms: the average heat pump “can put out three times more heat than the power they consume”, they deliver about three to five times the heating of a gas heater for the same input energy, and they cost roughly a quarter as much to run as a bar or column heater. In Auckland’s mild but often damp climate, that efficiency is what makes a heat pump the default choice rather than a luxury.
But the price range is wide, and it depends entirely on what type of system you need, how big your space is, and how complex the installation is. A small bedroom unit is a very different investment from a ducted system that heats and cools an entire house.
This guide breaks down current 2026 pricing for heat pump installation in Auckland, from single-room hi-wall units through to multi-split and ducted systems, and it covers what the Healthy Homes heating standard actually requires if the property is a rental. We size and fit heat pumps for Auckland homes and rentals through our licensed trade network, alongside the rest of our property maintenance services.
Heat Pump Installation Costs by System Type
| System Type | Total Installed Cost | Best For |
|---|---|---|
| Small hi-wall (2.5–3.5kW) | $1,500–$3,000 | Bedrooms, small offices |
| Medium hi-wall (5–7kW) | $2,500–$4,000 | Standard living areas, open-plan |
| Large hi-wall / floor console (7–9kW) | $3,500–$5,500 | Large living areas, poor insulation |
| Multi-split (2–4 indoor units) | $5,000–$12,000 | Multiple rooms, compact footprint |
| Ducted system | $7,000–$20,000+ | Whole-house heating and cooling |
Hi-Wall Units — The Most Common Choice
A standard hi-wall unit is the system most Auckland homes end up with. One indoor unit on the wall, one outdoor unit directly behind it through the wall. This “back-to-back” installation is the simplest, fastest and cheapest setup, typically taking 4–6 hours. EECA’s own installation guidance points the same way: the indoor unit should sit high on an exterior wall away from corners, and the outdoor unit ideally within about 15 metres of the indoor air outlet with clear space either side for airflow.
For a medium-sized living area (25–40m²), a 5–7kW hi-wall unit from a quality brand like Mitsubishi, Daikin, or Fujitsu costs $2,500–$4,000 installed. That’s the sweet spot for most Auckland households.
Floor Console Units
Floor consoles sit low on the wall near floor level. They’re a good choice for rooms with limited wall space or where you want heat delivered lower in the room. They typically cost $500–$1,000 more than an equivalent hi-wall unit due to the different installation requirements.
Ducted Systems — Whole-House Comfort
Ducted heat pump systems distribute heated or cooled air through ceiling or underfloor ducts to every room in the house. They’re the premium option at $7,000–$20,000+ depending on home size and the number of zones, but they provide even comfort throughout and are invisible inside the home.
Ducted systems make the most sense in new builds or major renovations where ductwork can be installed during construction. Retrofitting ducts into an existing Auckland home is possible, but it is more disruptive and more expensive.
One clarification worth making early, because the search results mix them up constantly: a hot water heat pump is a different product from a space-heating heat pump. It heats the cylinder rather than the room, it costs and saves different amounts, and it is covered in our guide to hot water cylinder replacement costs.
💡 Property tip: Many homeowners assume a multi-split system (one outdoor unit serving several indoor units) is cheaper than two separate single-split systems. It usually is not. Multi-split outdoor units are more expensive and more complex to install. Get quotes for both before deciding.
Ducted and Multi-Split Heat Pumps: What They Cost and When They Are Worth It
Once you move past heating one room, the question stops being “which unit” and becomes “how many rooms, and how do you get heat to them”. EECA splits the choices three ways, and the money follows the same split.
Single-split is one outdoor unit connected to one indoor unit heating one room. Multi-split connects one outdoor unit to several indoor units heating different rooms, which EECA describes as suiting larger homes. Ducted blows heated air through a duct system into multiple rooms, and EECA notes plainly that it can be more expensive upfront than the other options.
| Whole-home option | Installed cost | What you are actually paying for |
|---|---|---|
| Two or three separate hi-wall units | $5,000–$12,000 (using the hi-wall bands above) | Independent control per room, cheapest per room, several outdoor units on the wall |
| Multi-split (2–4 indoor units) | $5,000–$12,000 | One outdoor unit, tidier exterior, more pipework inside walls and ceilings |
| Ducted, single zone | $7,000–$20,000+ | Ceiling or underfloor ductwork, nothing visible on the walls, whole-house comfort |
| Ducted, multi-zone | Upper end of the $7,000–$20,000+ band | Zone dampers and controllers so you can heat the bedrooms and the living areas separately |
When Ducted Actually Pays
Ducted makes the most sense in a new build or a major renovation, where the ductwork goes in while the ceiling is open. Retrofitting ducts into a finished Auckland home is possible, and it happens regularly in single-storey homes with a generous roof cavity, but it means ceiling access in several rooms and it is more disruptive than any other option in this guide.
The honest test is the count. If you are heating one living area and a bedroom, ducted is hard to justify against two hi-wall units. Once you are heating four or more rooms and you want even temperatures without units on every wall, the ducted number starts to look reasonable rather than extravagant. Zoning is what pushes a ducted quote up, and it is also what makes ducted worth having: heating four bedrooms overnight that nobody is in is how a ducted system develops a reputation for being expensive to run.
Where a Ducted Quote Varies Most
Three things move a ducted price around more than the brand does. Roof cavity access and height, because a tight cavity slows every metre of duct. Number of zones, because each zone adds a damper, a sensor, and controller programming. And the return-air path, which in a retrofit often means a grille in a hallway ceiling and a discussion about where it can go.
Ask for the quote to be broken out by unit, ductwork, zoning and electrical. A ducted quote presented as a single number is impossible to compare against another single number.
What Affects Heat Pump Installation Cost in Auckland?
Installation Complexity
Standard back-to-back installation labour runs $900–$2,000. This covers about 90% of Auckland homes where the outdoor unit sits directly behind the indoor unit through a timber-framed wall with up to 3 metres of refrigerant pipe.
Non-standard installations push costs higher. A long pipe run from indoor to outdoor unit (more than 3m), a concrete or brick wall requiring core drilling, a multi-storey installation with the outdoor unit at ground level, or restricted access for the outdoor unit all add to the bill.
Electrical Requirements
Most heat pumps need a dedicated electrical circuit. If your switchboard has no spare way, or it needs upgrading to carry the load, electrical work can add $200–$600 to the installation cost. Older Auckland homes, particularly pre-1980s ones, sometimes need a switchboard upgrade as part of a heat pump install, and that is far better found at the quote than on install day.
Brand and Size
The three dominant brands in NZ are Mitsubishi Electric, Daikin, and Fujitsu. All three make excellent products and have strong NZ service networks. Premium brands with higher COP (Coefficient of Performance) ratings cost more upfront but deliver greater energy efficiency, which means lower power bills across the unit’s working life. EECA puts the life of the technology at around 15 years, so a difference of a few hundred dollars in running cost per year is not a rounding error.
Getting the size right matters. An undersized unit struggles to heat the room and runs constantly (high power bills, short lifespan). An oversized unit cycles on and off too frequently (inefficient, less comfortable). A good installer will calculate the correct size based on your room dimensions, insulation level, window area, and Auckland’s climate data.
Where Auckland Sits Against the Rest of the Country
Auckland quotes generally land at the upper end of the national ranges in the table above, for the ordinary reasons: labour rates, demand, and travel time across a spread-out city. Jobs on the rural fringe often carry a travel charge on top. Ask for it to be shown as a separate line rather than buried in the installation figure, so you can compare two quotes properly.
What a Heat Pump Installation Actually Costs in Auckland
Put the pieces together and a typical Auckland job lands in a predictable range. For the standard back-to-back install that covers most Auckland homes, budget $2,500 to $4,000 all-in for a 5–7kW living-area unit, covering the unit, standard bracketry, up to 3m of pipe, and commissioning. A small bedroom unit fitted the same way sits nearer $1,500–$2,500. Worth holding against that: EECA’s national figure for a heat pump is around $4,400 including purchase price and installation, which is a useful sanity check on any quote that comes back well outside these bands in either direction. Where the number climbs in Auckland specifically is core-drilling through brick or block, long pipe runs on two-storey homes, or a switchboard with no spare ways. Get those flagged at the quote stage rather than discovered on install day.
💡 Property tip: A heat pump only performs to its rating if the room holds the heat. Sorting ceiling and underfloor insulation at the same time lets you fit a smaller, cheaper unit and cuts the running cost — the two jobs are far better booked together than a year apart.
Heat Pumps for Rental Properties — Healthy Homes Requirements
If you’re a landlord, this section is the one that matters most.
Healthy Homes compliance note — the standard is a capacity figure, not a temperature: Tenancy Services states the heating standard as “one or more fixed heaters that can directly heat the main living room”, each at least 1.5 kW, together meeting the minimum heating capacity calculated for that specific room. There is no “gets the room to 18 degrees” test to pass — you calculate a required kW figure using the Heating Assessment Tool or the formulae in Schedule 2 of the Residential Tenancies (Healthy Homes Standards) Regulations 2019, then install heating that meets it. Open fires and unflued combustion heaters (a portable LPG bottle heater, for example) do not qualify at all, and a heat pump or electric heater must have a thermostat. Landlords in breach face financial penalties of up to $7,200. See the Tenancy Services heating standard and the options for calculating heating capacity.
Working Out the Capacity You Actually Need
This is where landlords get caught, because the number is not a guess and it is not the installer’s opinion. Tenancy Services offers three routes to the required capacity for the main living room: the online Heating Assessment Tool, the formulae set out in Schedule 2 of the Residential Tenancies (Healthy Homes Standards) Regulations 2019, or a professional assessment. The tool produces a report, and that report is what helps prove the property meets the requirement. There are two formulae, and the tool decides which one applies from your answers, with a newer formula used for properties that meet its definition of a modern dwelling.
Their own warning is worth repeating. An alternative tool or formula “cannot guarantee that the calculation will be correct under the healthy homes heating standard”, because a different tool may underestimate the capacity required. If a unit gets sized off a rule of thumb and the room needs more, the property fails on a figure, not on comfort.
Existing Heating, Top-Ups, and the Trap at Replacement Time
If the property already has heating, you may not need to add anything. Tenancy Services says you do not need more heating where one or more existing heaters were installed before 1 July 2019, each has a heating capacity greater than 2.4 kW, each meets the standard’s requirements (so no open fire, no unflued combustion heater), none is an electric heater other than a heat pump where the required capacity is over 2.4 kW, and the total is at least 80 per cent of the required capacity.
There is also a narrow top-up allowance. You can add a smaller fixed electric heater to top up existing heating if that heating was installed before 1 July 2019, the required capacity is more than 2.4 kW, and the top-up needed is 2.4 kW or less. Tenancy Services gives the worked example: a pre-July-2019 heat pump rated 3.6 kW in a room needing 6.0 kW can be topped up with a fixed 2.4 kW electric heater with a thermostat.
Here is the part that costs landlords money later. Tenancy Services is explicit that once that existing heat pump needs replacing through wear and tear, the concession goes with it, and you must then install qualifying heating that meets the full required capacity. A portfolio sitting comfortably on grandfathered heating today therefore has a capital cost queued up behind every ageing unit, and it is bigger than a like-for-like swap. Budget for the capacity you will need, not the capacity you have.
When the Standard Does Not Apply
There are heating-specific exemptions. They cover the case where it is not reasonably practicable to install a qualifying heater, and the case where the rental is a certified passive building. “Not reasonably practicable” has a defined meaning: a professional installer cannot access the area without substantial building work, without causing substantial damage to the property, or without creating greater health and safety risks than is normally acceptable. There is also a partial exemption where the landlord does not own the entire building, an apartment being the common case.
Two things do qualify that landlords often assume do not. Central heating meets the standard as long as it provides heat directly to the main living room and meets the required capacity. Geothermal heating can qualify in some properties, mainly around Rotorua. What you should not do is self-certify an exemption off a paragraph in a blog post. The exemptions are narrow, and they are read narrowly.
Which Heat Pump Suits a Rental, and What It Costs
For most Auckland rental properties, a 5–7kW hi-wall heat pump in the main living area is the most cost-effective way to achieve Healthy Homes heating compliance, assuming the capacity calculation supports it. At $2,500–$4,000 installed, it’s a one-off investment that keeps you compliant, reduces tenant complaints, and adds value to the property.
We work with landlords across Auckland who need heat pumps installed as part of a Healthy Homes compliance programme, usually bundled with ceiling and underfloor insulation, ventilation and the rest of the list through a single point of contact. Heating is only one of the five standards. If the ventilation rule is the next one on your list, our comparison of DVS, HRV and SmartVent systems for Auckland rentals covers what does and does not comply, the full Healthy Homes standards guide runs through all five, and the heating standard guide goes deeper on this one. If you are budgeting a portfolio rather than a single property, the breakdown of annual rental maintenance costs is the wider picture, and landlord repair obligations covers what has to happen when the heating fails mid-tenancy.
Running Costs for a Rental
Running cost is the tenant’s bill, not the landlord’s, but it still matters: a compliant heater a tenant refuses to use because it is expensive to run is a damp-house complaint waiting to happen. EECA puts a heat pump at around a quarter of the running cost of a bar or column heater and about a third of the cost of heating with gas, which is precisely why the standard steers landlords towards them. The detail sits in the running-cost section further down.

Who Is Allowed to Install It
EECA’s guidance is blunt on this point: a heat pump “needs to be installed by a licensed electrician”. Connecting the unit is prescribed electrical work, which means a registered person carries it out and you should receive the electrical Certificate of Compliance that goes with it. Charging and handling the refrigerant is separate specialist work again, which is why heat pump installs are quoted by installers rather than by general handymen.
Two practical consequences follow. A quote that says nothing about certification is a quote worth questioning, because the certificate is the document you need at resale, at an insurance claim, and in a tenancy file. And self-installing voids the manufacturer’s warranty, so the saving is usually theoretical.
💡 Property tip: The major brands run cashback and promotional offers at different points in the year, and installers know which ones are live. Ask before you sign, not after. Ask the same question about the old unit while you are there: some installers include removal and disposal in the price, and some bill it separately.
What a Heat Pump Costs to Run, and How to Keep That Number Down
Running cost is the half of the decision most quotes never mention, and for a heating system you will keep for around 15 years it matters as much as the install price.
EECA’s figures are the ones worth anchoring to, because they are national and independent. A heat pump could save the average household around $122 per year against what it replaces. It is the lowest-cost home heating option available, at around a third of the cost of heating with gas and roughly a quarter of the cost of running a bar or column heater. EECA also publishes a savings calculator that works off your own situation rather than an average, which is more useful than any figure a blog can quote you.
Four Habits That Change the Bill
EECA’s own running advice is unglamorous and it works.
- Set it between 18 and 21 degrees. At or above 18 to fight damp and mould, below 21 to save power. Every degree above that costs energy for comfort you will not notice.
- Do not run it 24/7. EECA is direct that the “leave it on all the time is cheaper” idea is a myth, and that running it constantly uses and loses more energy overall. Run it when you are home.
- Clean the filter monthly through winter. A vacuum or warm water on the removable filter, same principle as the filter in a dishwasher.
- Use the timer and leave the fan on auto. Warm the room just before you get home rather than arriving cold and cranking the temperature. Setting the fan to low for quietness reduces efficiency and raises the bill.
A unit that is serviced and running clean also holds its efficiency, which is the practical argument for getting a heat pump serviced rather than waiting for it to stop working.
Insulation Changes the Running Cost More Than the Unit Does
EECA’s advice on heat pumps opens with insulation for a reason: a well-insulated room means the heat pump does not have to work as hard, which shows up on the bill every month. It also shows up at the quote stage, because a room that holds its heat needs less capacity, and less capacity is a cheaper unit. Sorting ceiling and underfloor insulation at the same time is close to the only way to make a heat pump quote smaller rather than larger.
What a Heat Pump Quote Should Itemise
Most heat pump quotes are one line and a number, which makes comparing two of them guesswork. A quote you can actually assess separates out the following.
| Line item | Why it belongs on the quote |
|---|---|
| Unit make, model and rated heating capacity in kW | Without the kW figure you cannot check the sizing, and for a rental you cannot check compliance |
| How the capacity was determined | Room measurement and calculation, not a glance. For a rental, the Heating Assessment Tool report |
| Pipe run length and whether it exceeds the standard allowance | The single most common source of a variation on install day |
| Wall type and any core drilling | Brick, block and concrete cost more to penetrate than timber framing |
| Electrical scope and switchboard check | A dedicated circuit may be needed, and an old board may have no spare way |
| Certification and commissioning | The paperwork you need at resale, at claim time, and in a tenancy file |
| Removal and disposal of the old unit | Sometimes included, sometimes an extra, rarely stated unless asked |
| Warranty terms on unit and workmanship, separately | These are two different warranties from two different parties |
If two quotes are $800 apart, the gap is almost always hiding in pipe run, electrical scope, or disposal. Ask which, and one of the two quotes usually moves.

How much does it cost to install a heat pump in NZ?
Heat pump installation in New Zealand costs between $1,500 and $4,000 for a standard wall-mounted unit in 2026, including both the heat pump and professional installation. Most households pay $2,500–$3,500 for a mid-range hi-wall unit suitable for a standard living area. Ducted systems range from $7,000 to $20,000+ depending on home size and complexity.
How much does a heat pump cost to run in Auckland?
EECA puts a heat pump at the lowest-cost home heating option available: around a third of the cost of heating with gas, and roughly a quarter of the cost of running a bar or column heater. EECA estimates a heat pump could save the average household around $122 per year against what it replaces, and publishes a savings calculator that works off your own home rather than an average. The biggest levers on the running cost are setting the thermostat between 18 and 21 degrees, running the unit when you are home rather than continuously, cleaning the filter monthly through winter, and insulating the room so the unit does not have to work as hard.
What size heat pump do I need for my living room?
The right size depends on room dimensions, insulation quality, window area, and ceiling height. As a rough guide: 2.5–3.5kW suits bedrooms and small rooms (up to 20m²), 5–7kW suits standard living areas (20–40m²), and 7–9kW is needed for large open-plan spaces or poorly insulated rooms. A qualified installer should calculate the correct size based on your specific room.
Do landlords need to install heat pumps for Healthy Homes?
The Healthy Homes Standards require a fixed heating source in the main living area capable of heating to 18°C. A heat pump is the most common and efficient way to meet this requirement but it is not the only option — wood burners and flued gas heaters also qualify. Open fires and unflued portable LPG heaters are expressly excluded, and a fixed electric heater that is not a heat pump does not qualify where the required capacity exceeds 2.4 kW. The heating must be fixed (not portable) and appropriately sized for the room.
Can I install a heat pump myself?
No. EECA's guidance states that a heat pump needs to be installed by a licensed electrician. Connecting the unit is prescribed electrical work and should come with an electrical Certificate of Compliance, and charging and handling the refrigerant is separate specialist work again. Self-installing also voids the manufacturer's warranty, so the saving is usually theoretical. Use a registered installer and make sure the quote covers certification as well as the unit.
How much does a ducted heat pump cost in NZ?
A ducted heat pump system runs $7,000 to $20,000 or more installed, depending on the size of the home and the number of zones. EECA describes ducted systems as more expensive upfront than single-split or multi-split alternatives, and zoning is what pushes a quote towards the upper end, because each zone adds a damper, a sensor and controller programming. Ducted makes the most financial sense in a new build or a major renovation where ductwork can go in while the ceiling is open. Retrofitting ducts into a finished Auckland home is possible, most commonly in single-storey homes with a generous roof cavity, but it is the most disruptive option. As a rough test: below three or four rooms, two hi-wall units are usually the better value.
Is a multi-split heat pump cheaper than separate units?
Usually not. A multi-split connects one outdoor unit to several indoor units, which gives a tidier exterior and suits larger homes, but the outdoor unit is more expensive and the installation is more complex than fitting separate single-split systems. Multi-split installations run $5,000 to $12,000 for two to four indoor units, which overlaps heavily with the cost of the equivalent number of separate hi-wall units. The genuine advantages are one outdoor unit instead of several and less clutter on the exterior walls. Get quotes for both configurations before deciding.
What heating capacity does a rental need under the Healthy Homes heating standard?
There is no single figure, because the required capacity is calculated for the specific main living room. Tenancy Services requires one or more fixed heaters that directly heat the main living room, each at least 1.5 kW, together meeting the minimum heating capacity calculated using the Heating Assessment Tool, the formulae in Schedule 2 of the Residential Tenancies (Healthy Homes Standards) Regulations 2019, or a professional assessment. Open fires and unflued combustion heaters do not qualify, and a heat pump or electric heater must have a thermostat. You cannot use an electric heater other than a heat pump where the required capacity exceeds 2.4 kW, unless you are topping up qualifying heating installed before 1 July 2019. Landlords in breach can face financial penalties of up to $7,200.
What are the best heat pump brands in NZ?
Mitsubishi Electric, Daikin, and Fujitsu are the three most popular and trusted heat pump brands in New Zealand. All three offer reliable units tailored to NZ conditions with strong warranty coverage and wide service networks. Panasonic is also a quality option. Choose based on your specific needs, room size, and installer recommendation rather than brand loyalty alone.
How long does a heat pump last?
EECA puts the working life of the technology at around 15 years, and good maintenance is what gets a unit to the end of that rather than partway. Professional servicing keeps the refrigerant charge and the electrical side right. Filter cleaning is the owner's job and it matters more than people expect: EECA recommends vacuuming or washing the removable filter monthly through winter. For a rental, plan the replacement rather than waiting for the failure, because once a grandfathered pre-July-2019 heater is replaced the property has to meet the full required heating capacity.
How long does heat pump installation take?
A standard single-room wall-mounted heat pump takes 4–6 hours to install. Complex installations, such as multi-split systems, long pipe runs, or jobs requiring electrical upgrades, may take a full day. Ducted systems can take 1–3 days depending on the home size, the number of zones, and how accessible the roof cavity is.
