The weekly Carterton Market has been trading on the new Market Square outside the Town Hall since December 2014. The regular traders still trade every Thursday and they frequently welcome new members to trade alongside them.
The market operates from approximately 9am to 3pm. Regular attendees are the fruit and veg stall, bread and cakes, plants and flowers, gold and silver to buy or sell, fish van, burger and hot drinks van, fresh meat, cards and wrapping paper, rugs and carpets, and more recently a clothes stall. Since 2017 the Lloyds Bank mobile unit has attended the market too, since the closure of its Carterton branch.
