"This point of loss that Dane has recorded and researched himself is reflected by the title Post hoc - after this," says Stanhope. "Maybe we are in this world of artificial intelligence ... a post nature world ... it asks the question of where to from here?"
As New Zealand's representative at the biennial exhibition, Mitchell developed his initial idea for Post hoc alongside Stanhope and project curator Chris Sharp. He drew on his past work framing the world by exploring ideas about unseen substances, such as fragrances, with thoughts about vanished things and how speech could make them real once more.
His work appears alongside that of artists from the 89 countries represented at the exhibition which opens on Saturday
Mitchell said his intent was not necessarily to make a moral statement to the public: "I'm not interested in making a statement, but I am interested in those things circling the work. I understood the work would impinge or touch on topical notions, such as climate change and mass extinction. I like that the work negotiates all of these different realms but it is up to the viewer what they take from it."
Dame Jenny Gibbs, part of the selection panel that chose Mitchell as New Zealand's representative, said his work is particularly relevant at a time of growing concern around issues of climate change and species' extinction.
"When artists make a presentation, most of them try to make something that has some relevance," she said. "When we selected this piece we knew the world was worried about such issues such as extinctions."
Gibbs said the final project exceeds expectations with its complexity and technical sophistication.
"It gives me a great thrill to watch all these people walking past, being intrigued and talking about the project."
