This presentation discusses outcomes from an evaluation of the Health Sponsorship Council Smokefree Homes campaign, using information from five population surveys conducted annually since 2003. The overall goal of the campaign was to increase the number of parents and caregivers implementing and enforcing strategies to reduce exposure of children to second-hand smoke in homes and cars. Of between 2,000 and 2,500 adults surveyed each year, 500 to 1000 identified as Mäori. The survey data reveal greater responsiveness among Mäori parents and caregivers than people who do not identify as Mäori, with a large reduction in second-hand smoke exposure in Mäori caregivers’ homes.
