Lego Users Group Otago (Lugo) president Jaqui Hay said exhibitors from Auckland to Southland brought along their unique creations to showcase a collection of "awe-inspiring" sculptures to the public.
"There’s kids exhibiting, there’s adults exhibiting, teenagers; a huge amount of people have come to participate."
The event was organised in tandem with Lugo and the Dunedin Rotary Club, with all proceeds going to the Otago Youth Wellness Trust.
The day also included speed-build competitions, a cosplay parade, a blind-build competition and performances from magician Jonathan Usher and a brick-filled science show by Amadeo Enriquez-Ballestero.
