Yes, the competition has opened doors, and there is an exciting offer on the table yet to be confirmed, so he can't talk about that yet.
The Homai Te Pakipaki competition took up to five months. Wiz was in the second heat of five and being in the competition he got to meet other musicians.
"I did not expect to win," he says humbly.
It was a popularity contest, he said, with everyone from home texting for him, and added that it was also about the music.
Wiz's lively performance, flying dreadlocks that reach past his waist, and big, open smile, singing the Amy Winehouse's reggae/jazz version of Sam Cooke's Cupid with his own "twist on it", took him to the top.
"My first two songs were from Uncle Bob Marley. I felt comfortable with them and did not want to be known as a cheater, so I picked the Amy Winehouse version for the challenge."
He says his late mum, Tu Gardiner, inspired his love of music. And kapa haka at Cullinane College was another string to his musical bow.
And the nickname Wiz? "My sister Stacey gave that to me when I was a kid. I always had ants in my pants. I have three sisters and they are all down there [Wanganui]."
Last year Wiz moved to Auckland with his wife Shelley and 17-month old son Kingdom.
"She plays worship music, piano and guitar, and is an awesome singer."
