Every year, the New Zealand Naturist Federation holds a festival to coincide with the Annual General Meeting. The festival runs for seven days from 28 December to 3 January each year and generally includes a full sports programme, with trophies and medals fiercely fought for.
The actual dates can be altered of course, depending on the club hosting the event, and what day the AGM is to be held. Generally though, it is from 28 December thru 3 January.
There isn't just competitive sports played - a number of relaxing leisure activities (e.g. tai chi or water aerobics) and sometimes crafts are available too - so there is something for everyone.
In addition, the host club generally puts on entertainment each evening. This all depends on the size of the club of course and the budget for the event.
The Festival is a chance to reconnect with old friends and to make some new ones - a time to relax and "reboot" enjoying nude recreation together.
