A large New Zealand study has highlighted the prevalence of cyberbullying in Māori adults. Individuals aged 18-83 years (n = 6,529) who completed the questionnaire-based Māori Identity and Financial Attitudes Study in 2017 were included in the present study. On average, 19.3% of participants reported ever experiencing cyberbullying, and 4.1% reported experiencing cyberbullying within the past month. When analysed by age group, young adults (aged 18-25 years) experienced the highest rates of cyberbullying. Rates of cyberbullying were also higher among women and those identifying as a minority sexual orientation compared with men and heterosexuals. Individuals who identified as Māori as one of their multiple ethnicities experienced higher rates of cyberbullying than those who identified as Māori only. The study discusses practical and theoretical implications in light of Māori mental health outcomes.
