Insulating in the top of the South

Why insulation performs differently in the top of the South

Nelson, Tasman and Marlborough sit in H1 climate zone 3, one of the milder zones in the country. The whole territory is in Healthy Homes zone 3, so every rental here needs the higher R3.3 ceiling. 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

Nelson, Tasman and Marlborough sit in H1 climate zone 3, one of the milder zones in the country. The whole territory is in Healthy Homes zone 3, so every rental here needs the higher R3.3 ceiling.

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

The top of the South is in Healthy Homes zone 3. Every rental property must meet these minimums above and below all living spaces.

Wall insulationnot required

Walls are not covered by the standard, and in an uninsulated older home they are where most heat is lost. See retrofit wall insulation.
