The Gus Fisher Gallery in Auckland and Wellington's Adam Art Gallery are both currently hosting exhibitions celebrating architectural modernism. What is it about modernism that continues to fascinate and inspire? Ideas explores the nature of modernism and its impact on New Zealand with Julia Gatley, the author of the recently published 'Group Architects: Towards a New Zealand Architecture,' and Bob Fantl, a former colleague of the most celebrated modernist architect to work in New Zealand - the Austrian refugee Ernst Plischke.
