Outside formal naturist organizations, social nudity is practised in a variety of contexts in New Zealand culture. It is a feature of many summer music festivals, including Convergence, Kiwiburn, Luminate, Rhythm & Vines, and Splore, in a tradition going back to Nambassa in the late 1970s. It is also associated with the culture of rugby, most prominently in the nude rugby match held in Dunedin each winter from 2002 to 2014 (and sporadically thereafter) as pre-match entertainment for the first professional rugby game of the season, and in the mock public holiday "National Nude Day", an event in which viewers of the TV2 talk show "SportsCafe" were invited – chiefly by former rugby player Marc Ellis, the show's most irrepressibly comic presenter – to send in photos and video of themselves performing daily activities in the nude.
