Typical Costs for Heat Pump Installation in New Zealand in 2025

Heat pump installation costs can vary depending on the system type, capacity, installation complexity, and the size of your home. Here’s a general overview based on recent information:

• Single split systems: Commonly used for heating or cooling a single room or open-plan area; installation costs generally range from NZD $1,500 to $3,500.
• Multi-split systems: These connect multiple indoor units to one outdoor unit, allowing temperature control in several rooms; costs typically start around NZD $4,500.
• Ducted systems: Designed for heating and cooling an entire home with concealed ductwork, with installation costs ranging from about NZD $6,750 up to over $19,000.

For example, in Wellington, installation costs typically fall between NZD $2,500 and $4,500 depending on home size and specific system models.

Factors Affecting Installation Costs

Several elements influence the overall price of heat pump installation, including:

• Installation complexity: Situations that require longer refrigerant pipe runs, difficult access, or roof/wall mounting tend to increase installation expenses.
• Heat pump capacity and home size: Larger or less insulated homes generally need more powerful units, which can lead to higher costs.
• Additional features: Models offering Wi-Fi connectivity, air purification, or smart home integration may involve higher initial expenses, potentially offering energy savings over time.
• Regional differences: Prices may vary by location, with cities such as Auckland often showing higher charges compared to Christchurch or Hamilton, reflecting the local cost of living.

Government Support: Warmer Kiwi Homes Subsidy

To assist with heat pump installation costs, the Warmer Kiwi Homes programme provides subsidies that can cover up to 80% of installation expenses, with a maximum grant of NZD $3,000.

Eligibility for the Subsidy

To potentially qualify for this subsidy, the following conditions generally apply:

• The home must have been constructed before 2008.
• You need to be the owner-occupier of the property.
• The main living areas should not currently have a fixed heating source.
• The property must be located in EECA-eligible zones, or the occupant holds a Community Services Card, or the home is in a low-income area.
• The home should be insulated adequately, or considerations are made if insulation is structurally not possible.

If eligible, this subsidy can significantly reduce your personal expenditure on heat pump installation.

Choosing Heat Pump Systems for Your Home

Selecting an appropriate heat pump depends on your home’s layout and your heating and cooling needs:

• Single Split Systems: Suitable for smaller homes or individual rooms; generally more affordable and simpler to install.
• Multi-Split Systems: Appropriate for multiple rooms with independent temperature control; involve a higher initial investment but provide greater flexibility.
• Ducted Systems: Designed for whole-home climate control with discreet ductwork; installation is more complex and usually costs more.
