John Paul College student Tacy Aitchison, 17, said she was considering a building career before the tour but wanted to see first-hand what to expect.
Rotorua Lakes High student Vincent Hindman, 15, said he started the day "curious" about building, and now knew about a large number of options for entering the industry.
Woodworking was one option, as a visit to Lee Bros Joinery revealed.
Joe Andrews, who was in his second year of apprenticeship at the joinery and led the factory tour, said the day was about "showing kids the bigger scope of options" and proving they did not need to go to university to have a successful career.
The purpose of the tour was to educate more people about the industry and help the govement meet the growing demand for apprentices, BCITO chief executive Warwick Quinn said.
It was stated in the government's 2016 Budget that $14.4 million would be pumped into apprenticeships over the next four years.
