Māori were less likely to gain access to publicly funded bariatric surgery than New Zealand European or Other European patients in the Counties Manukau Health bariatric programme from 2011 to 2017. A total of 2519 patients were referred to the programme and 1051 patients received bariatric surgery. Of these 68% were Other European and 63% were New Zealand European compared with 42% Asian, 41% Māori and 28% Pacific (p<0.05). Differences in socio-demographics, comorbidity or attrition did not explain the significantly lower likelihood of Māori receiving bariatric surgery (OR 0.53; 95% CI 0.42–0.68).
