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.
New Zealand cuisine
Many New Zealand gatherings feature a custom known as 'bring a plate' or 'potluck' in which each guest will bring a plate of food to share. This allows people to host large groups without incurring serious expense. Similar customs include guests bringing salads or meat to a barbecue. Most New Zealand parties are 'BYO' (bring your own alcohol), but in this case the drinks are not usually shared. This is especially the case with parties hosted by young people, who cannot usually afford alcohol for more than a few people. One exception is sometimes the 21st birthday party, which will often be funded by the host's family. Weddings are also normally catered for by the hosts and their family.
