Christchurch Lego exhibition enthrals public

A new wave of interest in Lego is encouraging families to be creative together.

Around 75-billion of the colourful plastic bricks are sold around the world each year.

Newshub went along to a Lego event in Christchurch to see what is possible with a little imagination - and a lot of bricks.

Lego is shaking off its image as a kids toy, with fans of all ages checking out the impressive creations on display at the Christchurch Brick Show.

"Oh absolutely. I think adults are realising that they're not strange if they have this interest in playing with their kids' toys," Christchurch Brick Show organiser Sarah Stapleton told Newshub.

Nathan Hake's played with the bricks for years, but last year's show inspired him to take it seriously.

"And it was just thinking, I can do stuff like that. And really just like pushing yourself to build bigger and better things," the first-time exhibitor says.

Experienced Lego builder Centuri Chan got his extended family into the hobby. Even his mum has caught the Lego bug.

"She'd help me sort out my Lego, and from that she started building with it," he says.

The toy's latest success is thanks to Three's hit reality TV show Lego Masters.

Chan worked with Australian 'Brickman' Ryan McNaught a few years ago, on the 'Wonders of the World' exhibition.

"Yeah [it was] an awesome experience, just working in a workshop full of Lego, building large scale models. Something that not everyone gets the opportunity to do," Chan says.

Some models are inspired by real-life, like one of the Christchurch cityscape. Others are based on films, with Star Wars proving a popular choice.

Anthony Ducre spent seven-months building an interactive Death Star, with visitors able to send their phones on a journey around the model.

"And this way they can also take home a souvenir of their own trench run. Because [let's] face it, everyone wants to be in that movie, everyone wants to be in that trench, everyone wants to destroy the Death Star," he says.

And take home a memory to inspire the next wave of Lego creations.
