More than 4500 people attended a weekend-long exhibit to all things Lego in Invercargill at the weekend.

Some of the more than 60 exhibitions at ILT Southland Stadium included a live build of a topographically accurate map of Milford Sound, and a train display based on trains that once ran in Southland. 

Brick shows take place across New Zealand, but Southland Brick Show event organiser Gavin Evans said the south seemed to offer something pretty unique and special for exhibitors. 

Crowds had a "really refreshing" interaction with exhibitors, talking with them and showing interest instead of just taking a photo and moving on. 

For that he gave his hats off to the public, which has developed a loyal following for the show over the past six years.

The majority of exhibitors came from Southland, but some brought their delicate creations all the way from the North Island. 

Any funds raised from the event, hosted by LUG South, go into buying gifts for sick kids in Southland, Mr Evans said. Being able to continue doing charitable work throughout the rest of the year was only thanks to the public's support of the event. 

Mr Evans also wanted to thank the event's "incredible" sponsors, including main sponsors the ILT Foundation and Toy World, as well as Back9 Creative Studio and McCallum's Group.

"Without these sponsors to support us, our event wouldn't be as profitable, so we wouldn't make as much money to distribute throughout the community."
