It's not everyday pre-schoolers need to don hard hats and hi-vis coats.
But yesterday was no ordinary day for 16 four-year-olds from BestStart Maunu Village early childhood centre.
The children were taken behind the hallowed fences and on a tour of the Hundertwasser Art Centre construction site at Whangārei's Town Basin.
Centre manager Erica Johnson said with the focus on Hundertwasser in Whangārei the early childhood centre decided to make it one of the topics for their learning.
At the site, the children got to watch the crane moving, as well as hear about the foundations and the reinforcing steel being used.
Johnson said the children asked questions about how much the project is costing, when it's going to be ready, why it will be different colours and importantly - who's moving the crane.
The $29 million project, inspired by the artist, is due to be completed in late 2020.
The students were also shown pictures of what the finished building will look like.
"It was awesome to get in and for them to see this and how they're going to construct it."
The group finished their tour with a trip to Te Kakano where they heard it was built to give local contractors the chance to "practise" building something that didn't have any straight lines.
Project spokesman Greg Hay said everyone was really chuffed to have the children at the site.
He said that Trigg Construction went out and got little hard hats and hi vis vests for the visit. "So that was really cute".
"It's a community project and we want to keep the community involved as much as possible."
Work on the concrete and steel beams which link the piles together at the site is continuing. The next big step will be the pouring of the concrete floor slab later this month.
