Auckland winters are short. The damp is not.
A heat pump quote is three decisions wearing one price: the unit, the installation, and the electrical circuit behind it. Auckland guides put most homes at $2,500–$3,500 installed for a mid-range hi-wall, and at least one local firm publishes a from-price including the unit. The surprise cost is rarely the heat pump; it is the switchboard that cannot feed it.
Is this your stream?
A first heat pump for a cold living area, replacing a failed unit, adding a second unit to a bedroom, or the dedicated circuit and switchboard work any of those need. Supply-and-install packages keep it to one quote.
Whole-home ducted is a $7,000–$20,000+ project with zoning and ceiling-space questions, and a multi-split sits between the two. If that is the conversation, treat it as a renovation-scale project and get multiple designs, not a single package quote.
What it costs in Auckland
The published Auckland band
Superior Property Services' 2026 guide puts a standard wall-mounted heat pump at $1,500–$4,000 installed in Auckland, with most households paying $2,500–$3,500 for a mid-range hi-wall suited to a standard living area.
The published package
Viper Electrical supplies and installs Mitsubishi Heavy Industries heat pumps from $3,000 including unit and installation, with a $20,000 workmanship guarantee and servicing from $205.55+GST.
The install component
Consumer NZ's survey found install costs alone ranged $750–$1,350. Add $200–$600 of electrical work when the switchboard needs attention (Superior's guide), more if the board itself is due.

Common mistakes
Buying the unit before checking the switchboard: most heat pumps need a dedicated circuit, and Superior Property Services' Auckland guide notes older pre-1980s switchboards can add $200–$600 of electrical work, or a full board upgrade on ceramic fuses. Assess the board before the unit arrives.
Comparing supply-and-install packages on the headline price only: what size unit, which brand, how long the pipe run, and whether the electrical connection is included all sit under the headline. Viper's from-$3,000 package names the brand; ask everyone else the same questions.
Sizing by floor area alone: insulation, ceiling height, window area and which way the room faces all change the kilowatts needed. An undersized unit runs constantly and never quite heats; an oversized one short-cycles. Insist on a proper sizing conversation.
Forgetting the outdoor unit placement: Auckland's townhouses and apartments have body corporate rules and neighbour boundaries to respect, and the outdoor unit's noise and airflow matter. Check body corporate rules before quoting a unit title property.
Skipping the service schedule: heat pumps need regular servicing to hold efficiency. Viper publishes servicing from $205.55+GST, which is the number to compare against a premature replacement.
Assuming ducted is just a bigger hi-wall: ducted systems run $7,000–$20,000+ installed (Superior's guide) and need ceiling space, zoning decisions and a very different install. It is a renovation-scale project, not an appliance swap.
FAQ
How much does a heat pump cost installed in Auckland?
Superior Property Services' 2026 Auckland guide puts a standard wall-mounted unit at $1,500–$4,000 installed, with most Auckland households paying $2,500–$3,500 for a mid-range hi-wall. Viper Electrical publishes supply-and-install packages from $3,000 including a Mitsubishi Heavy Industries unit. Ducted whole-home systems run $7,000–$20,000+.
What does the install alone cost?
Consumer NZ's survey found installation costs varied from $750 to $1,350, more than the units themselves varied. Superior's guide notes the electrical side can add $200–$600 if the switchboard needs work, which is why supply-and-install packages are easier to compare.
Why does the switchboard matter?
A heat pump draws sustained load on its own dedicated circuit. Modern boards usually have the spare way; pre-1980s boards often do not, and ceramic fuse boards may need upgrading first. Get the board checked before the unit is ordered.
Hi-wall, multi-split or ducted?
A single hi-wall ($2,500–$3,500 installed in most Auckland homes) heats one living area. Multi-splits run several rooms off one outdoor unit. Ducted heats the whole house invisibly but costs $7,000–$20,000+ and needs ceiling space. Most households start with one hi-wall in the main living area.
What paperwork or rules apply?
The electrical connection is prescribed work, so the licensed electrician issues a Certificate of Compliance for the circuit. In apartments and townhouses, the outdoor unit usually needs body corporate approval. Beyond that, sizing and placement are the decisions that decide whether the unit actually heats the room.
Most Auckland homes land at $2,500–$3,500 installed for a mid-range hi-wall (Superior's guide), with Viper's Mitsubishi Heavy Industries packages from $3,000 as the published benchmark. Prime covers the east and Waikato, Neon and LB Electric handle the circuit and board side on published rates, and Excel backs installs with 24/7 callout. Check the switchboard first, size the unit properly, and budget the $200–$600 electrical extra on older boards.
