Heat pumps are one of the most energy-efficient ways to heat and cool your home in New Zealand. They improve indoor air quality, reduce your carbon footprint, and help cut energy bills—all while maintaining year-round comfort.
But how much do heat pumps cost to install and run in New Zealand? And what should you expect to pay based on your home size, layout, and preferences?
This guide from OneAir, New Zealand’s trusted HVAC professionals, breaks down the average cost of heat pumps in NZ, the key pricing factors, and tips to help you make the most informed decision.
What Affects the Cost of a Heat Pump in NZ?
When budgeting for a new heat pump, it’s essential to understand the variables that influence total cost—from the unit itself to installation and long-term savings.
Here are the 6 biggest factors that affect heat pump costs in New Zealand:
Heat Pump Type and Size
Heat pumps come in various types:
High wall (split system) heat pumps – best for single rooms
Ducted heat pumps – ideal for whole-home heating and cooling
Multi-split systems – connect multiple indoor units to one outdoor unit
The bigger your home or the more rooms you want to heat or cool, the larger or more complex your system needs to be. That means higher upfront costs.

Installation Requirements
The complexity of installation significantly impacts your overall cost. Factors that drive up installation costs include:
Limited access to roof, crawlspaces, or ceilings
Homes without existing electrical infrastructure or needing upgrades
Multi-storey buildings
Need for extra ducting, drainage, or wall brackets
A basic back-to-back installation is typically cheaper than a custom or multi-unit setup.
Energy Efficiency Rating
More energy-efficient heat pumps come with a higher price tag—but they consume less power, helping you save more in the long run. Look for:
Energy Efficiency Ratio (EER)
Seasonal Energy Efficiency Ratio (SEER)
Higher-rated units are better for the environment and your electricity bill.
Brand and Build Quality
Top-tier brands (e.g., Mitsubishi Electric, Daikin, Panasonic) usually cost more—but offer superior performance, better materials, quieter operation, and longer-lasting components. A reputable brand also typically includes longer and more reliable warranty support.
Smart Features and Add-Ons
Modern heat pumps may come with:
Wi-Fi control via mobile app
Programmable timers
Motion sensors
Advanced air purification filters
These add convenience but also increase the cost.
Warranty and After-Sales Support
Manufacturers' warranties vary from 2 to 5 years for parts and/or labor, depending on the brand and installer. Some providers offer extended warranty plans that include regular servicing. This might cost more upfront but can be worth it for peace of mind.
