Contemporary artist Kate Newby, who put together her winning $50,000 installation with the help of abseilers, was reduced to shouting directions from a distance because of the Auckland Art Gallery's heritage status.
At the weekend, the 33-year-old was awarded the Walters Prize, which is named for the late New Zealand artist Gordon Walters and aims to make contemporary art more widely recognised and debated.
Visitors walking their way through Newby's Crawl out your window move up a concrete ramp, which functions as the entrance and is pitted with bottle caps and potholes, then on through a yellow corridor lined with a cotton sheet.
The piece continues around a corner, where a carpet is scrawled with a chalk message, before it travels outside, with two spraypainted rocks sitting on the shingled roof of the Grey Gallery, which are viewed through a window.
The building's heritage status meant Newby, whose work has been shown in Europe, Australia, central and north America, wasn't allowed to set a foot on the roof.
