How Much Does a Heat Pump Cost to Install in NZ?
Installing a heat pump is one of the smartest investments you can make for a New Zealand home. They heat more efficiently than electric heaters, cool in summer, and can significantly reduce your power bill year-round. But what does heat pump installation actually cost in 2025?
Average Heat Pump Installation Costs
| System Type | Supply & Install Cost | |---|---| | Single-room (wall-mounted) | $1,200 – $2,500 | | Multi-head (2–3 rooms) | $3,500 – $6,000 | | Multi-head (4+ rooms) | $5,500 – $10,000+ | | Commercial or ducted | $5,000 – $20,000+ |
These prices include the heat pump unit, refrigerant lines, electrical work, and installation labour. Always get at least three quotes — prices vary significantly between brands and installers.
Top Heat Pump Brands in NZ
New Zealand's most popular heat pump brands are:
- Mitsubishi Electric — widely regarded as the gold standard for reliability and efficiency
- Daikin — excellent energy efficiency ratings, very popular in NZ homes
- Fujitsu — solid mid-range option with good after-sales support
- Panasonic — strong performer, often competitively priced
- Haier and Samsung — budget-friendly options worth considering for smaller rooms
For most NZ homes, Mitsubishi and Daikin dominate the market due to their robustness in varying climates from Northland to Southland.
What Affects the Price?
Unit size (kW): A 2.5kW unit suits a small bedroom; a 7kW+ unit is needed for large open-plan living areas. Bigger units cost more to buy and install.
Brand: Premium brands like Mitsubishi or Daikin cost more upfront but often have better energy efficiency (higher star ratings = lower running costs).
Installation complexity: A straightforward back-to-back install (unit on an exterior wall with a short refrigerant run) is cheapest. Long refrigerant runs, difficult access, or high-rise installs add cost.
Electrical work: If your switchboard needs upgrading or a new circuit is required, expect an additional $300–$800 from an electrician.
Number of indoor heads: Multi-head systems sharing one outdoor unit are more cost-effective per room than separate systems.
The Warmer Kiwi Homes Subsidy
If you own and live in your home, you may be eligible for the Warmer Kiwi Homes programme, which provides up to 80% off the cost of a heat pump or insulation for eligible homeowners.
To qualify, your home generally needs to be:
- Built before 2000
- Owner-occupied
- In a lower income or high health-need area
Check your eligibility and find approved installers at the EECA website. This is a genuine subsidy that could reduce a $2,000 installation to under $400 — absolutely worth checking before you pay full price.
Heat Pumps vs Electric Heaters: Running Costs
A heat pump is 3–5x more efficient than a standard electric heater. For every 1 kW of electricity consumed, a heat pump produces 3–5 kW of heating. This means:
| Heating Method | Annual Running Cost (typical NZ home) | |---|---| | Electric panel heaters | $1,800 – $3,000+ | | Heat pump (quality brand) | $400 – $900 | | Gas heating | $900 – $1,800 |
Over 5–10 years, the running cost savings easily outweigh the installation cost.
Tips for Getting the Best Heat Pump Quotes
- Get three quotes — prices can vary by $500–$1,500 for the same job
- Ask about efficiency ratings — higher COP (Coefficient of Performance) = lower power bills
- Check the installer is certified — look for F-Gas certification and ensure they use licensed electricians
- Ask about warranties — most brands offer 5-year parts warranties; some installers offer extended cover
- Ask about servicing — annual filter cleans and checks extend unit life significantly
