Heat pumps
In New Zealand, EECA publishes a single upfront figure for a heat pump including purchase and installation. It is a typical number from that page, not a range and not a quote. Australian split-system prices are not listed here, because this page does not have a government or industry rate to cite for Australia.
A heat pump quote should name the room, the capacity and whether the price is supply and install. Ducted and multi-room systems are different products from a single high-wall unit.
Published figures
Heat pump, purchase and installation
Around $4,400 NZD
EECA's published upfront figure for purchase price and installation together. The page does not give a date for the figure. It is a single typical figure, not a surveyed range, and it is for New Zealand.

After a grant
These amounts are what a household may pay once a grant is applied. They are not the price of the job.
Household share of an eligible Warmer Kiwi Homes heat pump
$400–$700 NZD
EECA says an eligible household can expect to pay this much toward a heat pump, depending on size and brand. The grant is only for households that qualify, and the page says the funded product is a high-wall heat pump sized for one room. This is a co-payment, not the retail price of a heat pump.

What the publisher says about running costs
Heating saving in EECA's worked example
$122 NZD
EECA says a heat pump could save the average household this much a year. The footnote is a 3-person household in Auckland, in a moderately insulated house, heating during the day on 1–2 days a week in cooler months, switching from piped gas, and it excludes daily connection charges.

What changes the price
- One room or the whole house. EECA describes single-split, multi-split and ducted systems, and says ducted systems can cost more upfront. The cited figure is not labelled as a ducted whole-house price.
- Who is allowed to install it. EECA says installation needs a licensed electrician. The outdoor and indoor units also need a sensible run of pipe and a place for the outdoor unit to breathe.
- Grants are not the retail price. Warmer Kiwi Homes can leave an eligible household with a much smaller co-payment. That co-payment is listed separately below. It is not what a heat pump costs to buy and install.
- The room, not the brochure. EECA says a funded high-wall unit is sized for the room it is installed in, not the whole house. A quote that ignores ceiling height, sun and insulation is guessing.
- Running cost is a separate claim. EECA's yearly saving is a worked example for one type of Auckland household switching from piped gas. Read the conditions on that line before you treat it as your bill.
Questions to ask
- Is this a single room unit, a multi-split or a ducted system?
- What capacity is specified for this room, and what is excluded?
- Does the price include supply, installation, pipe runs and an electrical connection?
- Will a licensed electrician do the electrical work?
- If a grant is mentioned, what do I pay, and does my house qualify?
- What are the product and workmanship warranties?
Common questions
Why is there no Australian dollar figure?
The cited install price is EECA's New Zealand figure. This guide does not borrow it as an Australian air-conditioning price. For an Australian quote, use the questions above and compare like for like.
Is the grant co-payment the cost of the heat pump?
No. It is what EECA says an eligible household may pay after funding. The retail install figure is the separate line above it.
