H Guthrie Smith's 1921 book Tutira: The Story of an NZ Sheep Station is credited with being New Zealand's first significant environmentalist publication. It was also the inspiration for stage director and designer Sam Trubridge to create a live work exploring New Zealand's mythical clean green image. Sam's calling his work Ecology in Fifths, and he's revisiting it ten years after first presenting it as a work in progress. Lynn Freeman talks with Sam Trubridge, first asking him why he's dusted it off now? Ecology in Fifths opens at Te Whaea National Dance & Drama Centre. And he's hoping to take the work to the Hawkes Bay Arts Festival and to Tutira for a special site-specific performance.
