Epidemiology of binge drinking
Concerns over binge drinking by teenagers has led to a review of liquor advertising being announced by the New Zealand government in January 2006. The review considered regulation of sport sponsorship by liquor companies, which at present is commonplace. Previously the drinking age in New Zealand was 20, then dropped to 18 in 1999.
Prostitution in New Zealand
There appears to be no law prohibiting a person under 18 from being a client of a prostitute, thus the legal age for this is presumably 16, the legal age of consent in New Zealand.
