Sales and efficiency data

Publication date: October 2025

For the past 25 years EECA has brought energy savings to homes and businesses.  

EECA regulates energy-using products, and each year we report on the energy savings that were achieved as a direct result of these products being sold. 

See the Energy Efficiency (Energy Using Products) Regulations 2002(external link) 

These regulations continue to provide significant energy and carbon savings for New Zealand homeowners and businesses.

Sales trends 2005-2025

In early 2025 we commissioned an in-depth analysis looking back over the last two decades of sales data for residential and commercial products.  

These reports outline a number of trends over time, in terms of sales volumes and product efficiencies. They also consider how external factors, such as Covid lockdowns, cost-of-living pressures, fluctuations in the number of new homes being built, and changes in interest-rates may have all have influenced consumer decisions when buying new appliances and equipment.
