Construction costs in New Zealand have shown an upward trend. In September, costs increased by an average of 0.2%, as price drops in plasterboard linings and GIB products were offset by rising expenses in plumbing, waterproofing, and diesel. Timber was a primary driver of inflation, with structural timber rising by 4.4% and plywood cladding by 5.6%.

By the third quarter, residential building costs in New Zealand rose by 1.7%, marking the fastest quarterly increase since late 2022 and bringing the annual growth rate to 4.8%. This increase, which exceeds the long-term average of 4.0%, is attributed to higher costs for materials, freight, and fuel, specifically noting price hikes in structural steel, PVC, sealants, and petroleum-based plumbing products.
