It's recycling in the name of child's play.
A group of Whanganui children spent Saturday building a giant maze out of recycled material as part of the Global Cardboard Challenge and now they've opened their creation up to the public.
One of the organisers Catriona Atkinson said the event was about encouraging kids to play and create with cardboard boxes.
"The kids mostly did it with a bit of support. It has a lot of potential for kids."
She said about 10 children were involved in making the maze and such events helped children develop a positive connection with the recycling centre.
