It's not a bad achievement for someone who's been painting since he was a teenager but, with no formal fine arts training, is regarded as an "outsider artist".
Asked to donate one of his paintings to the Art of Giving exhibition, he didn't hesitate.
The Art of Giving has been organised by the Bayleys Foundation, part of the real estate agency, which partners with the Make-A-Wish New Zealand to ensure youngsters with life-threatening medical conditions can have their wishes come true.
Around 200 art enthusiasts, gallery owners and collectors are expected to attend tonight's invitation only event with live and silent auctions scheduled.
Tucker is in good company with around 25 other artists donating work including Raymond Ching, Shane Cotton, Max Gimblett, Robyn Kahukiwa, Fiona Pardington and Peter Stichbury.
