The appropriate system depends on factors like your home’s size, existing setup, budget, and heating/cooling requirements.

Types of Heat Pumps and Associated Costs

Air Source Heat Pumps

Air source heat pumps, which extract heat from the outdoor air, are a widely used option in New Zealand. These include:

• Split systems: Consisting of one outdoor and one indoor unit, typically used for heating or cooling specific rooms.
• Multi-split systems: Use one outdoor unit connected to multiple indoor units, allowing temperature control in several rooms without ductwork.

Prices for air source heat pumps usually range from NZD 1,500 to NZD 6,000, providing affordable options for many homes.

Ducted Heat Pump Systems

Ducted systems condition entire homes through ducts and ceiling vents and often feature zoning options for different areas. They provide quieter operation without visible indoor units.

Installation costs in New Zealand typically range from NZD 8,000 to NZD 15,000 for average-sized homes. For larger or more complex homes, or where premium brands and features are selected, prices may reach NZD 15,000 to NZD 25,000. These estimates generally include equipment, ductwork, controls, and labour.

Ground Source (Geothermal) Heat Pumps

Ground source heat pumps use pipes buried underground to extract heat, and due to more involved installation requirements, prices start around NZD 10,000 and can go up to NZD 30,000.

Water Source Heat Pumps

These systems, usually applicable in commercial settings or specific residential cases with access to natural water sources, tend to be less common and often have higher costs.

Pricing for Daikin Heat Pumps in 2025

Daikin is a recognized heat pump brand in New Zealand, noted for reliability and energy efficiency.

• Single-split Daikin heat pumps typically cost between NZD 2,500 and NZD 6,000, varying by model, capacity, and features such as inverter technology and smart integration.
• Multi-split and ducted Daikin systems generally start around NZD 10,000, with prices varying according to system size and installation requirements.

Costs may also vary by region due to factors such as labour rates and demand, with places like Auckland generally seeing higher prices than Christchurch.

Factors Affecting Installation Costs

Various elements influence installation expenses:

• Home size and layout: Larger or multi-level homes generally need bigger systems and more ductwork.
• Existing ductwork: Homes already equipped with ducts may have lower installation costs.
• Installation complexity: Structural challenges, limited roof space, or heritage home considerations can increase labour and material costs.
• Insulation and ceiling height: Poor insulation or high ceilings might require more powerful systems.
• Timing: Installation during off-peak seasons (spring or autumn) may result in more competitive pricing.
• Brand and features: Premium brands and advanced controls often carry higher initial costs but may offer improved efficiency and durability.

Expected Running and Maintenance Costs

• Annual maintenance is commonly estimated at NZD 150 to NZD 300, covering activities such as filter cleaning and system checks to maintain efficiency.
• Operating costs for basic split systems can range from approximately NZD 400 to NZD 800 per year, depending on factors like home insulation, climate, system size, and usage habits.

Regular maintenance plays a role in prolonging system life and maintaining energy efficiency.

Available Financial Incentives and Support in New Zealand

To promote energy-efficient home improvements, New Zealand offers various rebates and grants, including:

• Warmer Kiwi Homes program
• Retrofit Your Home Scheme

Additionally, certain local utility companies provide incentives for installing energy-efficient heat pumps. It is advisable to review the eligibility criteria for these programs and apply when considering your budget.

Suggestions for Managing Heat Pump Costs in 2025

• Plan installation during less busy contractor periods to potentially access better rates.

Regional Variations in New Zealand

While this overview provides general pricing information relevant across New Zealand, cost variations occur regionally. For example, Auckland often has higher installation and equipment prices compared to cities like Christchurch, reflecting differences in living costs, labour charges, and market demand.
