The Cardrona Bra Fence was a controversial tourist attraction in Central Otago, New Zealand. The fence was on a public road reserve adjacent to farm property in the Cardrona Valley area southwest of Wanaka.
The Bra Fence began at some point between Christmas and New Year 1999, when four women's bras were attached to the wire fence alongside the road. The original reason for the bras being attached to the fence is currently unknown. News spread of the addition, which was left on the fence by the local landowners, and more bras began to appear. By the end of February there were some 60 bras, but at about this time they were all removed anonymously. This was reported in the local press, and the story gained widespread dissemination through the New Zealand media, leading to more bras appearing.
By October 2000, the number of bras had reached around 200, and again the fence was cleared of bras and this time the story spread even wider, as the fence had by this time become to some a quirky tourist attraction, and media sources from as far afield as Europe became interested in the fence. Due to this interest the number of bras being added to the fence personally or sent to be added increased dramatically. In early 2006, the number of bras attached to the fence stood at close to 800.
