Method An online survey was conducted with 3698 participants aged between 14 and 20 years (M = 17.1; SD = 1.8) in New Zealand. The survey asked about social media use and exposure to and engagement with alcohol product marketing on their preferred platforms, alcohol consumption patterns, hazardous drinking (AUDIT-C scores) and purchasing alcohol online.

Results Nearly three-quarters of the sample who responded to questions about exposure to alcohol marketing (70.6%; n = 1541) reported seeing marketing on at least one social media platform, with older respondents (18–20 years) more likely to report exposure than younger respondents (14–17 years); no differences were found across gender, ethnicity or socioeconomic groups. Over one-third of those who responded to questions about engagement (40.7%; n = 850) reported engaging with alcohol marketing and this varied by age, gender and ethnicity. Recall of exposure to alcohol marketing was less strongly associated with online purchase and having ever drunk alcohol than was engagement with alcohol marketing, which was also associated with hazardous drinking.
