Updated 29 Oct 2026

A heat pump is one of the few home upgrades you notice every day of the year. The decision that matters most is size: too small and the unit works hard for little reward, too large and you pay for capacity you never use.

The price table sets out typical installed prices for a standard back-to-back job, drawn from published price guides. Put your own quote beside those figures, size for size, to see whether it is fair.

Large high-wall, about 8 kW (open-plan living)	$3,500 to $5,500

A rule of thumb NZ installers use, for a room with a standard 2.4 m ceiling. High ceilings, big windows and open-plan spaces need more, so an installer should confirm it.

What a heat pump costs to install in Pukekohe

A standard back-to-back install means the indoor unit sits on an outside wall with the outdoor unit directly behind it, as close as the property allows. That is the arrangement behind the installed prices, and it covers most rooms in a typical home.

The small high-wall unit, around 2.5 kW, suits a bedroom or small room. The medium unit, around 5 kW, suits a lounge, and the large one, around 8 kW, is for open-plan living. A ducted system covers the whole house.

The energy label is the place to start. It shows heating output at 7°C and 2°C outside and cooling at 35°C, so ask for quotes on those same figures rather than one headline number. The sizing guide matches a unit to a room, and the national cost guide sets these figures in context.

What pushes a heat pump quote up or down

Two jobs can look alike on paper and land far apart once someone has walked the property. What moves a quote:

A short back-to-back run, easy access and a switchboard with room to spare pull the other way.

Get the quote in writing and check what it leaves out. Under the Fair Trading Act a quote must not mislead, hidden costs included, and under the Consumer Guarantees Act, where no price has been set, you pay only a reasonable price.

A longer pipe run between the indoor and outdoor units
Awkward access or height for the outdoor unit
A wall bracket or a floor-level pad for the outdoor unit
Extra electrical work, such as a new circuit or a switchboard upgrade
Removing an old unit
A larger unit, or a ducted system in place of a high wall

Paying for a heat pump in Pukekohe

One Pukekohe installer mentions finance on its website, so a payment plan is worth asking about directly.

Warmer Kiwi Homes, run by EECA, funds heat pumps for eligible owner-occupiers, and eligibility depends on holding a Community Services Card or SuperGold Combo Card, or living in a qualifying area. None of the Pukekohe installers mention the scheme on their websites, so ask when you call. The grants guide explains who qualifies and how an application works.

Heat pump cost questions in Pukekohe

Does it matter if an installer is tied to a brand?

No Pukekohe installer lists itself as an authorised dealer for a particular brand on its website, so a quote can name more than one make. Ask which brands are on offer, which one the price is based on, and who handles a claim if the unit fails.

Will frost change which heat pump I choose?

Frosts can occur anywhere in New Zealand, and inland and southern towns see colder winters. Ask how a unit behaves on a cold morning and whether the outdoor unit has anything to protect it from ice. That question is better raised before you sign than after.

Is a floor console better than a high wall unit?

Where wall space is tight, a floor console sits under a window and pushes heat out at floor level. Two Pukekohe installers name floor consoles on their websites and 3 name high wall units, so both can be quoted locally. Ask to see photos of each in a finished room.

What should I ask about the warranty?

Warranty terms appear on the websites of 3 Pukekohe installers, so the detail is worth pinning down before you commit. Ask what the cover includes, whether labour comes with the parts, and whether keeping it valid depends on servicing. Have the answer written into the quote.
