Colonisation has deeply harmed Maori communities, seriously and consistently undermining their vitality, aspirations and potentials, particularly since the 1860s, at inestimable cost to the entire nation. The British arrival in Aotearoa commenced a relationship between two very different peoples that has profoundly influenced their distinct and collective fortunes ever since. Despite manifest breaches of te Tiriti o Waitangi, this relationship has centred settler interests ensuring that Maori sovereignty has been displaced in favour of colonial hegemony, entrenching longstanding, preventable inequities in health and other important domains of social life. In this paper we trace some broad indicators of relational health and wellbeing in Aotearoa and consider how Maori thinking about whenua, health and wellbeing might lead healing opportunities for people and whenua. We outline ways in which a unified, dynamic, relational Maori concept based on whenua as the determinant of health could contribute. We believe this could expand, strengthen and revitalise prevention, protection and promotion approaches, to counter the injustices of colonisation, contribute toward health equity and move toward just, sustainable shared futures for the benefit of all New Zealanders.

Background Ethnic disparities in cancer survival have been documented in many populations and cancer types. The causes of these inequalities are not well understood but may include disease and patient characteristics, treatment differences and health service factors. Survival was compared in a cohort of Maori (Indigenous) and non-Maori New Zealanders with colon cancer, and the contribution of demographics, disease characteristics, patient comorbidity, treatment and healthcare factors to survival disparities was assessed. Methods Maori patients diagnosed as having colon cancer between 1996 and 2003 were identified from the New Zealand Cancer Registry and compared with a randomly selected sample of non-Maori patients. Clinical and outcome data were obtained from medical records, pathology reports and the national mortality database. Cancer-specific survival was examined using Kaplan–Meier survival curves and Cox hazards modelling with multivariable adjustment. Results 301 Maori and 328 non-Maori patients with colon cancer were compared. Maori had a significantly poorer cancer survival than non-Maori (hazard ratio (HR)=1.33, 95% CI 1.03 to 1.71) that was not explained by demographic or disease characteristics. The most important factors contributing to poorer survival in Maori were patient comorbidity and markers of healthcare access, each of which accounted for around a third of the survival disparity. The final model accounted for almost all the survival disparity between Maori and non-Maori patients (HR=1.07, 95% CI 0.77 to 1.47). Conclusion Higher patient comorbidity and poorer access and quality of cancer care are both important explanations for worse survival in Maori compared with non-Maori New Zealanders with colon cancer.

Alcohol consumption and heavy drinking in young adults have been key concerns for public health. Alcohol marketing is an important factor in contributing to negative outcomes. The rapid growth in the use of new social networking technologies raises new issues regarding alcohol marketing, as well as potential impacts on alcohol cultures more generally. Young people, for example, routinely tell and re-tell drinking stories online, share images depicting drinking, and are exposed to often intensive and novel forms of alcohol marketing. In this paper, we critically review the research literature on (a) social networking technologies and alcohol marketing and (b) online alcohol content on social networks, and then consider implications for public health knowledge and research. We conclude that social networking systems are positive and pleasurable for young people, but are likely to contribute to pro-alcohol environments and encourage drinking. However, currently research is preliminary and descriptive, and we need innovative methods and detailed in-depth studies to gain greater understanding of young people’s mediated drinking cultures and commercial alcohol promotion.
