Doug the Digger rolled up to Roslyn School in his big rig to deliver his story about the importance of reading books.
Doug the Digger is Alistair McIntyre, and he's passionate about reading and getting books into homes.
McIntyre had to re-learn how to read after a major accident that sparked a career change.
"I had to face my fears," he said.
He's been with Duffy Books for 20 years and coming up to delivering 1000 school assemblies throughout New Zealand.
McIntyre is one of Duffy's Books in Schools role models, with the energy and enthusiasm to get kids wanting to read books.
He told the Roslyn School assembly he was 25 when his arm was crushed, and that changed the course of his life.
When he was five McIntyre said he could not wait for the school holidays to go out and work with his dad. At 17 he already had two businesses of his own.
But now he's inspiring kids to read, and showed them how he started on his new quest to become Doug the Digger, and how he drew his childlike drawings before he found an illustrator.
