"It starts to play on your mind a bit, finishing second or third so many times, so to get up and win here is a huge thrill. It means a lot to me to win on the Charles Tour it has been a long time coming."
Moorhead, who was part of New Zealand's Eisenhower Trophy-winning team in 1992, last tasted victory at the Tahiti Open in 2011. He has finished runner-up twice on the Charles Tour and third at the Muriwai Open in 2011.
In the women's field, North Harbour golfer Lita Guo secured her first national title after carding a one under par in the final round to win by six shots from Wellington No 1 Julianne Alvarez.
Guo, who recently claimed a bronze medal at the Australian Youth Olympics as part of the New Zealand mixed team, was delighted to win for the first time on the Charles Tour.
"I have had a few runner-up finishes and top fives but to win is a great feeling," said the 17-year-old. "I played all right today - not as well as I have in the other rounds - but it was good enough to win by six. To get my first national title after how I played this week was great."
