EECA test results of electric hot water cylinders
In 2018/19, the Energy Efficiency and Conservation Authority (EECA) tested 12 commonly installed hot water cylinders against NZ's Minimum Energy Performance Standards (MEPS) to ensure they meet the requirements of the regulations. Of the 12 tested, only 4 met the NZ standards.

An article published on Stuff discusses the test results and the implications.
