Features
Read full description

Art+Object is New Zealand’s leading auction house, offering regular specialist catalogues of New Zealand and international historical, modern and contemporary art and applied art. Art+Object, located at 3 Abbey Street, Newton, Auckland, New Zealand, was founded in early 2007 with the goal to bring a more contemporary voice to the Australasian auction scene. Directors Leigh Melville and Ben Plumbly bring decades of experience in the art and auction worlds together with significant business and professional achievements. Art+Object has pioneered the presentation of contemporary art and objects in an auction context; our very first auction set this direction and received great support from New Zealand collectors. Art+Object Directors are regular contributors to industry journals, public speakers, guest auctioneers, media commentators and have sat on peer review panels to public art institutions. Art+Object holds ten to twelve auctions per annum. These are distinguishable by virtue of their often distinct theme and approach, along with industry leading catalogue design, exhibition display and online marketing which includes regular video presentations, online bidding and live streaming of auctions. These catalogues can be found in the archive section of our website. With the Art+Object app, you can preview, watch and bid in our auctions from your mobile / tablet device.
