"Everyone back home has been supporting me and cheering me on, it's been phenomenal."
Fellow Kiwi and teammate, 20-year-old Niamh Fisher-Black, finished 21st overall, but claimed second on the final stage with a strong ride.
"Getting my first WorldTour podium is amazing," said Fisher-Black.
"The situation was a little daunting, as I had not ever been in the position where I could go for a win in such a big race. I had to dig deep to stay up there.
"Over the last 5km, I just hung in there and waited for my opportunity. At 300m to go, I didn't look behind me, but just around the last corner, I was passed and was pipped on the line.
"It was a little frustrating, but I can't complain, having just finished second on a stage in such a renowned WorldTour race."
Elsewhere, Fisher-Black's brother Finn also finished second on the most recent stage of the Ronde de I'sard in France.
Niamh and Finn are set to represent New Zealand at the world championships this week, as is Harvey, who is a chance for a strong result in the women's road race.
New Zealand champion Shane Archbold also claimed one of the best results of his career at the Tour of Slovakia, finishing third overall after consistently strong performances over the four stages.
