Marton's Caleb Arthur and all of the New Zealand Black Stacks team who attended the World Championships in Orlando in April will be at the 2018 NZ Sport Stacking Open Championships in Wellington this Queen's Birthday Weekend.
Nearly 30 competitors will take part in the second sanctioned national tournament of the year.
The goal for several of them will be to impress the 2019 Black Stacks selectors, looking ahead to the 2019 World Championships in Spain.
The event is being held at the Northland Memorial Community Centre.
Arthur's New Zealand team came back from Orlando with one trophy and 37 medals, while he is the 2017 overall national champion.
