How to Find a Reliable Heat Pump Installer in NZ (2026)
Heat pumps are the most popular home heating and cooling solution in New Zealand, and for good reason -- they are highly efficient, clean, and effective in NZ's climate. With government subsidies available through the Warmer Kiwi Homes programme and rising electricity prices making efficiency more valuable than ever, 2026 is a popular year to install. This guide explains how to find a reliable installer and avoid the pitfalls.

Licensing Requirements for Heat Pump Installation
Heat pump installation in NZ involves both refrigeration/HVAC work and electrical work. Both elements require licensed professionals:
- Electrical connections: must be carried out by an EWRB-registered electrician
- Refrigerant handling: must be carried out by a person with an HVAC/R licence under the Refrigerant Handling Licence scheme
Most professional heat pump installation companies have both qualified electricians and licensed HVAC technicians on their teams. Always confirm both qualifications before proceeding.
What to Look for in a NZ Heat Pump Installer
- Both EWRB and HVAC/R qualifications on the installation team
- Experience with the brand they are installing: heat pump brands vary in installation complexity and the installer should have brand-specific training
- Correct sizing: an undersized heat pump will not heat your space adequately; an oversized one is inefficient. A good installer does a proper heat load calculation before recommending a unit.
- Warranty support: confirm that both the product warranty and the installation warranty can be supported locally
- Clean installation: refrigerant lines and electrical cables should be neatly run in conduit, not exposed or roughly taped
Warmer Kiwi Homes Subsidy in 2026
The Warmer Kiwi Homes programme provides subsidies toward the cost of heat pumps and insulation for eligible NZ homeowners. In 2026, eligible households may receive up to 80 percent of the cost of a heat pump installation. Eligibility is based on income, location, and home type.
| Check your eligibility Visit energyefficiency.govt.nz to check whether your household qualifies for the Warmer Kiwi Homes subsidy before engaging an installer. You must use an approved supplier for the subsidy to apply. Ask your installer whether they are registered under the programme. |
Questions to Ask a Heat Pump Installer
1. Are your installers both EWRB-registered and HVAC/R licensed?
2. How do you calculate the right sized unit for my space?
3. Are you a registered installer under the Warmer Kiwi Homes programme?
4. What brand and model are you recommending and why?
5. What does the installation warranty cover and for how long?
6. How will the refrigerant lines be run and finished?
Top Heat Pump Brands Available in NZ in 2026

- Daikin: strong reputation for quality and wide product range
- Fujitsu: popular mid-range option with good NZ service network

Brand matters, but installer quality matters more. A well-installed system from a reputable mid-range brand will outperform a poorly installed system from a premium brand.
Frequently Asked Questions
Do I need a building consent to install a heat pump in NZ?
Generally no for a standard wall-mounted heat pump. However, if installation requires penetrating an exterior wall in a way that affects the building envelope significantly, or if it is part of a larger project, consent may be required. Your installer should advise you.
How long does heat pump installation take in NZ?
A standard single split system installation takes 3 to 6 hours. Multi-split and ducted systems take 1 to 3 days. The outdoor unit location, cable run distance, and wall construction all affect the time required.
How often should a heat pump be serviced in NZ?
Most manufacturers recommend a service every 1 to 2 years. A service includes cleaning filters and coils, checking refrigerant levels, inspecting electrical connections, and testing performance. Regular servicing extends the life of the unit and maintains efficiency.
