Nudist clubs (called "sun clubs") were established in Dunedin and Auckland in early 1938; the Auckland Sun Group went into recess shortly afterwards due to the outbreak of World War II. In 1958 the allied nudist clubs of New Zealand established the New Zealand Sunbathing Association, later renamed the New Zealand Naturist Federation. The Federation includes 17 affiliated clubs with a total membership (in 2012) of 1,600 people. In 2016 the Federation, in conjunction with Tourism New Zealand, hosted the World Congress of the International Naturist Federation at the Wellington Naturist Club, marking the second time the Congress had ever been held in the Southern Hemisphere.
