“There is staggering evidence that many homes in Aotearoa New Zealand are not meeting the heating and energy needs of their occupants. Data from the 2018 Census showed that this number could be upwards of 460,000 homes. This negatively impacts the incomes, health, and mental well-being of occupants.  Data from the 2021 General Social Survey showed that just under half of all respondents felt that their house was too cold all or some of the time.”
