He has been interested in graffiti art "since I can remember", but said it wasn't until Year 10 at Kamo High School that he was inspired by his science teacher to pick up the spray cans for artistic reasons.
"Some of the stuff we do now [like the workshops], I would have loved to have done back then."
The workshops came hot on the heels of a youth forum looking at ways to address tagging held last month.
The forum was organised by the Youth Space after figures from the Whangarei District Council (WDC) showed 24,673 tags had been cleaned up in the year to August. The council spends $500,000 a year on vandalism, including tagging removal.
"Tagging is something I definitely don't like seeing," Mr Duke said. "We hear how much money is spent on removing it."
One of the ideas to come out of the forum included dividing Butter Factory Lane up and dedicating each section of the wall to a different youth group, which would be required to look after it, said the WDC's Owen Thomas. Other ideas included having more youth workers to help Whangarei's young people make better choices and more solutions, such as workshops for young artists. "I found the exercise very engaging and positive, [it] was a great example of when you talk and listen to each other you often find out you want the same thing - to make things better," Mr Thomas said.
"We must remember not all youth deface/vandalise our community, only a few.
"This is not an excuse, vandalism is unacceptable but you need the right tools in the tool box to help fix this. Our city is full of awesome young people and we must help all of them to go forward because we all live here."
