New Zealand recorded 33,554 new dwellings consented in the year ended April 2025, according to Stats NZ, with subsequent monthly readings showing seasonally adjusted increases of 5.4 percent in July and 2.8 percent in November as the building cycle stabilised after a period of contraction. The data reflects a market where homeowners have increasingly prioritised renovating, retrofitting and adding to existing dwellings rather than rebuilding, a behavioural pattern that has supported sustained category growth for residential wellness equipment alongside more conventional renovation expenditure on kitchens, bathrooms and outdoor living spaces. Within this broader context, home thermal therapy infrastructure has emerged as one of the more consistent performers as buyers seek to integrate recovery and wellness functionality into existing properties.

The global infrared sauna market reached an estimated USD 2.08 billion in 2026 and is projected to expand to USD 3.64 billion by 2033, growing at a compound annual growth rate of 9.8 percent, according to Coherent Market Insights. Within the category, the residential application held the largest share of demand at 57.3 percent in 2025 according to Persistence Market Research, reflecting a sustained consumer shift toward home-based thermal wellness infrastructure. Alongside the broader category growth, electromagnetic field mitigation has emerged as a defining purchase criterion among health-focused buyers, with safety certification and independently verified low-EMF technology now ranking among the most consistently cited factors in residential sauna purchase decisions.
