For about four years he has been selling work at markets and painting murals. His mural work was splattered around the Bay of Plenty, including Waihī Beach, Katikati, Tauranga and Rotorua.
The pop-up park on Devonport Rd in the Tauranga CBD, along with Chorus power boxes dotted around the region, also featured his work.
The inspiration behind his winning entry titled The Voyager was pursuing the path perhaps less taken.
"It's about leaving the world of convenience behind and going out and exploring. It's about finding the beautiful and raw parts of the world. You don't know what's out there until you go out and find it."
He walked away from the competition with the cash prize, joking that the entry "paid off".
He said the money was in the bank and would go towards living costs.
Marc Spijkerbosch was "absolutely chuffed" to win the People's Choice Award.
He described his vivid and mind-bending piece as a 3D mural that "invited the viewer in".
This was his fifth time at the festival, and not the first award either - he scooped up prizes in 2008, 2009 and 2010.
He called the festival a "cool concept with high calibre artists coming from all around the world".
