Insulating in Manawatū
Why insulation performs differently in Manawatū
Palmerston North and the Manawatū sit in H1 climate zone 3, a step colder than Whanganui in zone 2. The region is exposed and windy, and an evenly filled cavity does more here than the mild average temperature suggests. Blown loosefill fills the cavity evenly and gets into the awkward places batts leave open, which is where most of the heat actually goes.

H1/AS1 moved to its sixth edition on 27 November 2025 and the schedule method was removed, so required R-values now come from the calculation method rather than a fixed table. Read the R-value guide or use the insulation calculators to work out what your build needs.
Manawatū is in Healthy Homes zone 1 and 2. Every rental property must meet these minimums above and below all living spaces.
Walls are not covered by the standard, and in an uninsulated older home they are where most heat is lost. See retrofit wall insulation.
