Researchers have identified that various character- istics of neighbourhoods exert an influence on the health outcomes and behaviours of local residents. Understanding the processes linking places to health provides con- siderable potential for a range of policy interventions. We review the New Zealand- based neighbourhoods and health research. Consideration is given to the types of neighbourhood characteristics, as well the range of health outcomes that have been studied. Finally, we suggest some priorities for further research into the mechanisms underpinning neighbourhood influences on health in New Zealand. Key words: health, health inequality, neighbourhood, New Zealand. It has long been recognised that the places in for residents’ health: physical (e.g. air pollu- which people live, work and play have direct tion), socio-cultural (e.g. social cohesion) and and indirect impacts on individual-level and community resource access (e.g. recreational population-level health outcomes. These ‘place facilities). effects’ occur independently of individual-level Policy interventions at the area level have a demographic attributes, such as age, sex and long history.
