Background The Aotearoa/New Zealand Government is aiming to end the tobacco epidemic and markedly reduce Māori:non-Māori health inequalities by legislating: (1) denicotinisation of retail tobacco, (2) 95% reduction in retail outlets and (c) a tobacco free-generation whereby people born after 2005 are unable to legally purchase tobacco. This paper estimates future smoking prevalence, mortality inequality and health-adjusted life year (HALY) impacts of these strategies. Methods We used a Markov model to estimate future yearly smoking and vaping prevalence, linked to a proportional multistate life table model to estimate future mortality and HALYs. Results The combined package of strategies (plus media promotion) reduced adult smoking prevalence from 31.8% in 2022 to 7.3% in 2025 for Māori, and 11.8% to 2.7% for non-Māori. The 5% smoking prevalence target was forecast to be achieved in 2026 and 2027 for Māori males and females, respectively. The HALY gains for the combined package over the population’s remaining lifespan were estimated to be 594 000 (95% uncertainty interval (UI): 443 000 to 738 000; 3% discount rate). Denicotinisation alone achieved 97% of these HALYs, the retail strategy 19% and tobacco-free generation 12%. By 2040, the combined package was forcat to reduce the gap in Māori:non-Māori all-cause mortality rates for people 45+ years old by 22.9% (95% UI: 19.9% to 26.2%) for females and 9.6% (8.4% to 11.0%) for males. Conclusion A tobacco endgame strategy, especially denicotinisation, could deliver large health benefits and dramatically reduce health inequities between Māori and non-Māori in Aotearoa/New Zealand.

The transport system influences everyone’s wellbeing on a daily basis. These impacts are both positive and negative and are borne directly and indirectly at a range of spatial and temporal scales and across different groups in society. Furthermore, they are often distributed unfairly and the people who are least able to use transport networks frequently bear the greatest costs. People also have various transport needs and these needs change throughout their lives. Due to these complexities, there is no straightforward answer as to how we should provide transport fairly. Policies and actions to decarbonise the transport system are urgently needed, but their equity effects are also important. We give a brief overview of distributive justice and equity in transport literature. We then develop a conceptual framework of distributive justice and a set of four principles to guide the application of the framework to transport policy. We then apply these to recent transport policies in Aotearoa/New Zealand, a country that shares common features with most highly motorised countries. We apply the Capabilities Approach to transport policy in a novel way that conceptualises transport policy as a social conversion factor which influences people’s ability to convert resources and opportunities into the things (‘beings and doings’) that they have reason to value. The consideration of transport policy as a conversion factor, rather than focusing on a specific capability, emphasises the role of transport policy as a promoter of a wide range of capabilities and highlights the inequitable distribution of positive and negative effects on people’s health and wellbeing. It also illuminates issues of power structures and procedural fairness in transport policy that are otherwise not covered by distributive justice approaches. Taking a broader view of distributive justice theory in transport provides a clearer picture of the impacts of transport on wellbeing and provides theory-based guidance on the actions to improve transport justice that can be readily integrated into existing policy institutions.

Environments play a critical role in enabling and supporting practices, and thus in creating and embedding social norms. For example, dispensing cigarettes to soldiers and providing ashtrays in public areas signalled smoking’s acceptability, reinforced its normativity within specific settings and helped entrench it as a social practice.6–8 However, environments may also discourage and extinguish social practices. More recently, smoke-free signage has declared that smoking is not acceptable within designated settings,9 10 while removal of large in-store tobacco displays sharply differentiated tobacco from normal consumer goods.11 12

Racial discrimination is recognised as a key social determinant of health and driver of racial/ethnic health inequities. Studies have shown that people exposed to racism have poorer health outcomes (particularly for mental health), alongside both reduced access to health care and poorer patient experiences. Most of these studies have used cross-sectional designs: this prospective cohort study (drawing on critical approaches to health research) should provide substantially stronger causal evidence regarding the impact of racism on subsequent health and health care outcomes. Participants are adults aged 15+ sampled from 2016/17 New Zealand Health Survey (NZHS) participants, sampled based on exposure to racism (ever exposed or never exposed, using five NZHS questions) and stratified by ethnic group (Māori, Pacific, Asian, European and Other). Target sample size is 1680 participants (half exposed, half unexposed) with follow-up survey timed for 12–24 months after baseline NZHS interview. All exposed participants are invited to participate, with unexposed participants selected using propensity score matching (propensity scores for exposure to racism, based on several major confounders). Respondents receive an initial invitation letter with choice of paper or web-based questionnaire. Those invitees not responding following reminders are contacted for computer-assisted telephone interview (CATI). A brief questionnaire was developed covering current health status (mental and physical health measures) and recent health-service utilisation (unmet need and experiences with healthcare measures). Analysis will compare outcomes between those exposed and unexposed to racism, using regression models and inverse probability of treatment weights (IPTW) to account for the propensity score sampling process. This study will add robust evidence on the causal links between experience of racism and subsequent health. The use of the NZHS as a baseline for a prospective study allows for the use of propensity score methods during the sampling phase as a novel approach to recruiting participants from the NZHS. This method allows for management of confounding at the sampling stage, while also reducing the need and cost of following up with all NZHS participants.

Ethical publishing practices are vital to tobacco control research practice, particularly research involving Indigenous (Indigenous peoples: For the purposes of this Special Communication, we use the term Indigenous people(s) to include self-identified individuals and communities who frequently have historical continuity with precolonial/presettler societies; are strongly linked to the land on which they or their societies reside; and often maintain their own distinct language(s), belief and social-political systems, economies and sciences. The authors humbly acknowledge, respect and value that Indigenous peoples are diverse and constitute many nations, cultures and language groups. Many Indigenous peoples also exist as governments in treaty relations with settler-colonial societies, and all Indigenous peoples have inherent rights under international law. The language and terminology used should reflect the local context(s) and could include, but are not limited to, terms such as Aboriginal, Bagumani, Cherokee, First Peoples, First Nations, Inuit, Iwaidja, Kungarakan, Lakota, Māori, Mѐtis, American Indian, Navajo, Wagadagam, Wiradjuri, Yurok, etc) people. These practices can minimise, correct and address biases that tend to privilege Euro-Western perspectives. Ethical publishing practices can minimise and address harms, such as appropriation and misuse of knowledges; strengthen mechanisms of accountability to Indigenous peoples and communities; ensure that tobacco control research is beneficial and meaningful to Indigenous peoples and communities; and support Indigenous agency, sovereignty and self-determination. To ensure ethical practice in tobacco control, the research methodology and methods must incorporate tangible mechanisms to include and engage those Indigenous peoples that the research concerns, affects and impacts.Tobacco Controlis currently missing an ethical research and evaluation publishing protocol to help uphold ethical practice. The supporters of this Special Communication call onTobacco Controlto adopt publication practice that explicitly upholds ethical research and evaluation practices, particularly in Indigenous contexts. We encourage researchers, editors, peer reviewers, funding bodies and those publishing inTobacco Controlto reflect on their conduct and decision-making when working, developing and undertaking research and evaluation of relevance to Indigenous peoples.Tobacco Controland other publishers, funding bodies, institutions and research teams have a fundamental role in ensuring that the right peoples are doing the right work in the right way. We call forTobacco Controlto recognise, value and support ethical principles, processes and practices that underpin high-quality, culturally safe and priority-driven research, evaluation and science that will move us to a future that is commercial tobacco and nicotine free.
