Transport and Wellbeing of Public Housing Tenants—A Scoping Review
The role of public housing in improving wellbeing for tenants and society is an important public policy issue. Public housing tenants in Aotearoa New Zealand have constrained incomes and their mode of transport has implications for their budgets, their wellbeing, and carbon emissions. Tenants’ daily life choices and wellbeing are influenced by the set of transport options available to them and the constraints and opportunities these options entai…
Travel Behaviour and Carbon Emissions of Residents of Public Housing Areas in Aotearoa, New Zealand
Public housing tenants in many countries have multiple challenges, often including socioeconomic disadvantage, family health and disability limitations, and compromised potential to earn income. An understanding of this group’s travel behaviours is particularly salient when policies to limit carbon emissions are being considered because such policies can exacerbate transport inequities. The current study makes use of an ongoing national travel su…
Population health, health equity and health system impacts of light vehicle electrification
BACKGROUND: Electrification of the light vehicle fleet is a core component of decarbonisation policy globally. As transport is an important determinant of health, this process will likely impact a range of pathways to population health, outside of averted climate change. METHODS: A transport-health multistate lifetable model for Aotearoa/New Zealand was used to model changes in the vehicle fleet and transport behaviour patterns that could be expe…
Adolescents’ perceptions of food outlets in the school neighbourhood and their unhealthy snacking behaviour on the way to and from school
Objective: To understand the relationship between adolescents’ unhealthy snacking behaviour during their school journey and their perceived and objective measures of food outlet availability in the school neighbourhood. Design: A cross-sectional survey enquired about socio-demographic information, school transport modes, perceived presence of food outlets in the school neighbourhood and unhealthy food purchase and consumption on the school journe…
Framing home injury
Like many countries in the OECD, Aotearoa NZ does not comprehensively regulate or enforce the safety of rental housing, despite evidence that the significant scale of home injury can be reduced through cost-effective home modifications. We examine the framing of home injury in media, political, and organisational discourse to identify barriers to creating and enforcing laws for safer rental homes. We find progress in addressing safety via rental …
Dietary Pattern Indicators among Healthy and Unhealthy Weight Adolescents Residing in Different Contexts across the Otago Region, New Zealand
Reported obesity rates for adolescents in different urban and rural areas are inconsistent. We examined indicators of healthy and unhealthy dietary patterns among 1863 adolescents aged 13-18 years with a healthy or excess body weight attending 23 secondary schools in four different settlement types across the Otago region, New Zealand. An online survey included demographics and dietary behaviours. Height and weight were measured, and body mass in…
Inclusive and collective urban home spaces
Housing and urban development in Aotearoa New Zealand. • Response to Government Policy Statement on Housing and Urban Development (GPS-HUD). • Wellbeing benefits of collectively-oriented housing and transport models. • Co-housing and papakāinga as transformational housing typologies. • Multi-year and multi-scale community-based research programmes
The Impact of Transport on Population Health and Health Equity for Māori in Aotearoa New Zealand
The current transport system in NZ, like many other car-dominated transport systems, has substantial negative impacts on health, at a similar level to the effects of tobacco and obesity. Transport contributes to health inequity, as Māori bear greater shares of the negative health impacts. Creating a healthier transport system would bring substantial benefits for health, society and the economy
Towards dwelling energy certification for New Zealand
With the impact of climate change, the use of both energy and resources that lock in future energy use is receiving heightened attention. New Zealand has lagged behind many similar countries in not requiring an explicit energy certification for dwellings. This paper reviews the form of energy certification used by similar countries and discusses the potential impact of applying the various forms to New Zealand dwellings. Specifically, it compares…
A Cost Benefit Analysis of an Active Travel Intervention with Health and Carbon Emission Reduction Benefits
Active travel (walking and cycling) is beneficial for people’s health and has many co-benefits, such as reducing motor vehicle congestion and pollution in urban areas. There have been few robust evaluations of active travel, and very few studies have valued health and emissions outcomes. The ACTIVE before-and-after quasi-experimental study estimated the net benefits of health and other outcomes from New Zealand’s Model Communities Programme using…

Measuring the Effect of Housing Quality Interventions
In New Zealand, as in many other countries, housing in the private-rental sector is in worse condition than in the owner-occupier housing sector. New Zealand residential buildings have no inspection regime after original construction signoff. Laws and regulations mandating standards for existing residential housing are outdated and spread over a range of instruments. Policies to improve standards in existing housing have been notoriously difficul…
Increasing active travel
BACKGROUND: There is increased interest in the effectiveness and co-benefits of measures to promote walking and cycling, including health gains from increased physical activity and reductions in fossil fuel use and vehicle emissions. This paper analyses the changes in walking and cycling in two New Zealand cities that accompanied public investment in infrastructure married with programmes to encourage active travel. METHOD: Using a quasi-experime…
An analysis of changes in mobility and safety of older drivers associated with a specific older driver on-road licensing test
Along with other relevant studies comparing older driver licensing policies across different jurisdictions, this study does not support the generalised use of on-road testing as an assessment mechanism for all older drivers
Increasing active travel
This multidisciplinary study provides a strong design for evaluating an intervention to increase walking and cycling in a developed country with relatively low baseline levels of active travel. Its strengths include the use of data from control cities as well as intervention cities, an extended evaluation period with a reasonable response rate from a random community survey and the availability of instrumental variables for sensitivity analyses
Modelling the effects of low indoor temperatures on the lung function of children with asthma
INTRODUCTION: While many epidemiological studies have shown that low outdoor temperatures are associated with increased rates of hospitalisation and mortality (especially for respiratory or cardiovascular disease), very few studies have looked at the association between indoor temperatures and health. Such studies are clearly warranted, as people have greater exposure to the indoor environment than the outdoor environment. OBJECTIVES: To examine …
O4-1.2 Identifying an optimal exposure metric for measuring the short-term effects of low indoor temperatures on asthmatic children's lung function
Introduction Many epidemiological studies have shown that low outdoor temperatures lead to increased mortality and hospitalisation, generally finding the strongest association to be with temperature below a given threshold measured at a lag of 7–14 days. In contrast, very little work has been done on the health effects of exposure to low indoor temperatures, and none on the best metric of this exposure, despite the fact that people have greater e…
P1-495 Measuring the placebo effect in unblinded randomised community trials
Introduction The double blinded randomised control trial has been developed to provide gold standard estimation of causal effects. However, in many circumstances it is impossible to design studies that meet this standard of blinding and placebo effects potentially affect the estimates. One example of a study where it was impossible to blind the participants is the Heating Housing and Health Study (HHHS). Here the intervention was the installation…
Assessing housing quality and its impact on health, safety and sustainability
BACKGROUND: The adverse health and environmental effects of poor housing quality are well established. A central requirement for evidence-based policies and programmes to improve housing standards is a valid, reliable and practical way of measuring housing quality that is supported by policy agencies, the housing sector, researchers and the public. METHODS: This paper provides guidance on the development of housing quality-assessment tools that l…
