Announcing the awards, Arts Review judge Andrew Clifford, of Te Uru Waitakere Contemporary Gallery in Auckland, said Wightman was an artist with an established practice who continued to push into new territory and to explore new approaches.
"This work uses digital technology, not to finesse something into an unnatural perfection, but to look at the qualities of being digital," Clifford said.
"The resulting artefacts, glitches and gridded frameworks allow the object to break down in interesting ways that play with scale and materiality to question the kind of scaffolding we use to construct images and objects."
Excellence awards of $1000 each were presented to Rick Rudd for his earthenware Teapot (Dalgleish Architects Excellence Award) and Glen Hayward for his wood, paint and resin work Fountain Solomon Guggenheim New York 2017 (Central City Pharmacy Excellence Award).
