Ethnic disparities in the receipt of publicly funded bariatric surgery were evident in the Counties Manukau Health service in a review of hospitalisation records between 1 January 2011 and 31 December 2017. From a total of 2519 referrals, 1051 patients underwent surgery; ethnicities were reported as Other European (68%), New Zealand European (63%), Asian (42%), Māori (41%) and Pacific (28%). Compared with people of European ethnicity, Māori and Pacific people had a significantly lower likelihood of receiving bariatric surgery with odds ratios of 0.53 (95% CI 0.42–0.68) and 0.3 (95% CI 0.23–0.40), respectively.
