Abstract

Abstract: Introduction and Aims: This study aimed to assess the early impacts of a 2013 law change to restrict the social supply of alcohol to under 18s in New Zealand by assessing changes in social suppliers' behaviour. Design and Methods: National surveys of drinkers aged 16–65 years were collected before (2013) and after (2015) the law change. Suppliers were asked: to whom they supplied alcohol, how often and how much; if the supplier thought the alcohol they provided would be shared; whether the supplier had permission to supply from parent/guardian, and if they supervised their supply. General estimating equation models were used to conduct analyses. Results: Sons and daughters were commonly supplied to, as were friends, but friends were supplied greater quantities on average [13 drinks compared to four drinks for sons/daughters (at baseline)]. Following the law change, friends were less commonly supplied to (8% decrease), were supplied with fewer drinks (down from 13 to 11 drinks) and there was greater supervision of social supply to friends (16% increase) (and to other relatives). However, the number of drinks supplied by parents increased from four to six drinks. Discussion and Conclusions: There was evidence of some early reductions in social supply in relation to the law change, in particular where the legislation aimed to have effect; specifically, less supply to friends under 18 years. We found no effect of the new law on parental supply. As quantities supplied are still very high, further policy restriction and public health interventions would be appropriate.
