Pukekohe's winters and homes
Frost on calm nights
Pukekohe EWS averages 4.2 ground frosts in June and 4.9 in July. Air frosts are rare, at 0.7 a year, but the ground-level cold is real.
Still, humid air
NIWA gives the station a mean wind speed of 9 km/hr, half Auckland Airport's 18, and a mean 9 am humidity of 90% in June and July.
The July average low
Wikipedia's table of NIWA's 1991 to 2020 normals gives Pukekohe a July mean daily minimum of 6.7 degrees, and July is the wettest month at 146.5 mm.
A town on a hill
Pukekohe sits on the northern slopes of Pukekohe Hill, part of the South Auckland volcanic field, and its fertile volcanic soils made it a market gardening centre.
Growing every year
Occupied dwellings rose from 8037 in 2018 to 9195 in 2023, and 341 new dwellings were consented in the year to March 2026.
Renters and wood smoke
36.0% of Pukekohe households didn't own their home in 2023, against 34.0% nationally. Across the Franklin Local Board area, 29.9% of homes burned wood as a main heat source.
What Pukekohe homes usually need
A heat pump that holds up near freezing. EECA says that where nights reach 2 degrees or lower, the heating capacity at 2 degrees should equal or beat the 7 degree figure. It also says that below 5.5 degrees the unit gives up some capacity to defrost the outdoor coil.
An outdoor unit with room to breathe. BRANZ asks for at least 500 mm clear on the air inlet and outlet sides and 100 mm of ground clearance. Mitsubishi Electric NZ says the more moisture in the air, the more freezes on the coil, so keep it out from under the deck.
A first heat pump in a new house. With hundreds of homes consented each year, plenty of jobs are new builds, and a ducted heat pump is simpler to plan while the ceilings are still open.
Moving off wood. If you're weighing a heat pump against another burner, the heat pump vs other heating comparison puts them side by side. EECA no longer takes new Warmer Kiwi Homes applications for wood burners.

What we'd do
If it were our Pukekohe house
We'd choose the model on its 2 degree heating figure, not the headline number, and put the outdoor unit on a north or west wall with clear air all round, as BRANZ suggests for the best heating. If it's a rental, we'd run Tenancy Services' heating assessment tool for the main living room before getting quotes, so every installer prices the same size.
