New Zealand's housing is some of the poorest quality and hardest to heat in the developed world. The private rented sector in particular offers the worst quality accommodation to the country's poorest and most vulnerable tenants. Previous research has established a range of economic and socio-cultural explanations for the prevalence of poor conditions in private rented accommodation with the 'principal-agent problem' dominating the debate. This paper reports the findings from research in Dunedin, a city with some of the coldest conditions and least energy efficient properties in the country. The study was undertaken in 2015 and involved 30 in-depth interviews with landlords exploring their attitudes towards improving the thermal performance and energy efficiency of their properties. The results revealed a shift in attitudes amongst landlords over a period of about 5 years, with many becoming more amenable to investing in insulation and low energy heat sources. This shift has ostensibly been driven by pressure from tenants who appear to be departing from established cultural norms and becoming intolerant of cold homes and high bills. The study highlights how socio-cultural factors, such as growing expectations regarding warmth and comfort in the home, can disrupt established cultural norms and economic rationales to bring about change.
