Hon Dr MEGAN WOODS: We know that the poor quality of some of New Zealand's housing stock has led to an unacceptable amount of avoidable hospitalisations linked to cold, damp, and mouldy houses. In 2011, a Motu study on the benefits of insulation found that the benefit-cost ratio was $4.66 for every $1 spent in comfort and wellbeing. It is my intention to update this study to also look at the impact of heat pumps under the programme, which were introduced in 2019.
