His Pit Stop workmates had other ideas.
“One of the boys was saying ‘it's your guitar'. I said ‘thanks for your positivity but stop saying that, I don't want to jinx it'.”
When the radio station called Kingi to say they were testing all entrants' phones, the Gisborne man thought no more of it.
Then Rock Drive show hosts Jay and Dunc phoned him back to announce live-on-air he had won Young's electric guitar.
“When they announced I was the winner I lost it. I was shocked, I was ecstatic, I couldn't believe it. My workmates jumped up and down and said ‘we told you, bro'.”
Along with Young's signature, the guitar comes with documentation that confirms its authenticity.
In Gisborne for Christmas with family, the Rock's Roger Farrelly personally delivered the AC/DC guitar to a rapt Kingi at work.
“I've had guitars in the past,” says Kingi.
“It's been a passion and now I'm inspired to get back into it. If I'm going to play I want to be decent.”
