Insulating in Southland

Why insulation performs differently in Southland

Southland sits in H1 climate zone 6, the coldest zone in the country, alongside Central Otago. The heating season is the longest in New Zealand, which is why insulation pays back faster here than anywhere else. Blown loosefill fills the cavity evenly and gets into the awkward places batts leave open, which is where most of the heat actually goes.

New builds, Building Code H1

Southland sits in H1 climate zone 6, the coldest zone in the country, alongside Central Otago. The heating season is the longest in New Zealand, which is why insulation pays back faster here than anywhere else.

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.

Rentals, Healthy Homes standard

Southland is in Healthy Homes zone 3. 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.
