[1][2] Bosshard was one of a number of European-trained jewellers who came to New Zealand in the 1960s and transformed contemporary jewellery in the country; others include Jens Hoyer Hansen, Tanya Ashken and Gunter Taemmler.
[5]: 135 In 1970 Bosshard's work was included in Silver, Gold, Greenstone at New Vision Gallery in Auckland, the first substantial exhibition of contemporary jewellery in New Zealand.
[4]: 67 In 1972 he was included in Craft 72, an exhibition of New Zealand potters, weavers, wood-turners and jewellers organised by the Queen Elizabeth II Arts Council and toured overseas through the Ministry of Foreign Affairs.
[4]: 66 In a 1985 interview Bosshard described his preference for using a limited number of machines in his jewellery making and avoiding pre-cut metals: 'If you buy pieces of silver cut to standard thicknesses, you are tempted to stay with those measurements.
The key piece here is an experiment with free form and a larger scale: a lineal strip of silver is bent into a striking electric signature.
[9]: 29 Bosshard has also played an important role as a teacher of younger jewellers, including Peter McKay, Vicki Mason and Lisa Walker.
[4]: 146 [10] Martha Moseth, writing in Craft New Zealand in 1985, stated When goldsmiths Kobi Bosshard and Stephen Mulqueen opened Fluxus in September 1983 they were prepared for a few risks including a slow start and indeterminate debt.
[8]: 15 The name 'Fluxus' was chosen 'for two reasons: for its reference to the 'flowing' agent, like Borax, that goldsmiths use and for the idea of flux, or change, which is part of the Gallery's philosophy of adapting to the needs of the artists and the community'.
