"I didn't make a whole lot of mistakes and made a few birdies at the end.
"In the first three games I was losing most of the way so it's pretty good to win them."
Smith is coached by Mount Maunganui Golf club's head professional Robert Rookes, who says his young charge learned how to battle through and still get results.
"He just took it a shot at a time and went through his processes," Rookes said. "He texted me after the second round and said he really wanted to win this thing. So his attitude is not about trying to do well and achieving what people perceive to be his level now; he is trying to win these things."
Smith is looking forward to going to America for the junior worlds in July and making the NZ Under-19 team to contest the Youth Olympics Games in Nanjing in August.
But making the Bay of Plenty team for the Toro Interprovincials in December is always in the back of his mind. "Hopefully I can make the team. Bay of Plenty has a very good culture that's for sure. Certainly they are good at winning."
