Mr Murphy initially entered at Memorial Park then tried again at the set up on Tremaine Ave.
"I got inside and got all ready but the power went out ... it died on me. So they rebooked me to do it at Te Manawa. I got the highest number of tickets on the day which put me through to the grand final."
Taking on three others at Memorial Park, Mr Murphy obtained the most tickets and gained bonus points answering questions from The Hits Manawatu presenter Darryl Mallett.
"He was inside the dome with us as a distraction, asking questions and we got one point for each one we got right. I got five right so, I think I must have got about 31 tickets."
As an avid Hits' listener, Mr Murphy says this is his first major prize. "I'm definitely a Hits fan, I've won movie tickets and things but nothing like this."
