Heat Pump Cost NZ 2026 — Supply, Install & Running Costs
Heat pump costs in NZ 2026 — supply and install prices for hi-wall, multi-split, and ducted systems. Brand comparison, running costs, and how to qualify for Warmer Kiwi Homes subsidy.
A heat pump is the most cost-efficient way to heat and cool a New Zealand home — delivering 3–5 units of heat for every unit of electricity consumed. In 2026, supply-and-install prices for a standard hi-wall unit range from $2,200 to $5,500 depending on brand, size, and location.

Brand Comparison
All major heat pump brands sold in NZ are manufactured in Japan or South Korea and are broadly comparable in reliability. Key differences:
Mitsubishi Electric — widely regarded as NZ's most reliable brand, with the best service network and the strongest range of cold-climate models (important for Southland, Central Otago, and Wairarapa). Premium price.
Daikin — strong reliability, excellent inverter technology, competitive in mid-to-large capacity ranges. Good parts availability.
Fujitsu — competitive pricing, well-established service network. Strong performer in the mid-range.
Panasonic — good value, solid reliability, slightly less dealer penetration than the top three.
LG / Samsung — competitive on price, increasingly common, still building service network depth in regional NZ.
For most NZ homes, any reputable brand from a licensed installer with a local service agent will perform well. The installer's quality and the commissioning process matter more than brand differences for most applications.
Warmer Kiwi Homes Subsidy
The government's Warmer Kiwi Homes programme funds heat pump installation for eligible homeowners. In 2026, qualifying homeowners can receive up to 80% of installation costs covered (up to $2,918 for heat pumps).
Eligibility: - Own and live in the home - Built before 2008 - Not a rental property - Receive a community services card / income-tested benefit OR live in a lower-income area (check by address on the EECA tool)
Check eligibility at warmerkiwihomes.govt.nz before paying full price. Approved providers handle the subsidy paperwork.
Heat Pump Running Costs
A typical 2.5kW heat pump running 6 hours per day in winter costs approximately $1.20–$2.40/day to operate at NZ electricity prices (35–40c/kWh in 2026). This compares to:
- Panel heater (2.4kW): ~$3.40–$4.10/day for the same heat output
- Electric bar heater (2kW): ~$2.80–$3.40/day
- Woodburner: depends heavily on firewood cost, typically $1.50–$3.00/day
Heat pumps are 2–4× more efficient than direct electric heaters. Over a full NZ winter, the running cost saving typically amounts to $300–$800 compared to panel heating.
What Size Heat Pump Do I Need?
Rough sizing guide for a typical NZ home (well-insulated):
| Room Size | Unit Capacity |
|---|---|
| Small bedroom (up to 15m²) | 2.0–2.5kW |
| Medium bedroom / office (15–25m²) | 2.5–3.5kW |
| Open-plan living (25–50m²) | 3.5–6.0kW |
| Large open-plan (50–80m²) | 6.0–9.0kW |
| Poorly-insulated older home | Size up by 20–30% |
A licensed installer should perform a proper heat load calculation before specifying your unit. Undersized units run constantly and don't reach setpoint; oversized units short-cycle and wear faster.
