We found this at the entrance of the Woollaston Estates winery in Nelson. The sculptor is MartÃ© Szirmay, and the piece is called Yantra for Mahana (I found that after some googling – there weren’t any signs around the piece.) It was commissioned by the winery for the site. There were other sculptures scattered around the grounds, and an art gallery on the premises. I’m glad no one was around to bother us, but definitely would have loved to see the other pieces and tasted the wine!
