Choi, 18, made history by winning the New Zealand Amateur at Titirangi at the weekend.
It followed her victory in the national strokeplay championship earlier this year and solidified her status as the best amateur female golfer in New Zealand.
Choi (Takapuna) carried a 2-up lead over Jeong into the afternoon session of the 36-hole final, and sealed victory with a birdie on the 31st hole to post a 6&5 win.
"I won both the New Zealand strokeplay and New Zealand Amateur this year, so I feel really great," Choi said.
"Apparently, Lydia [Ko] didn’t get the two in one year, so I’m hoping I’m the only one in New Zealand history."
While Choi took the chocolates, she was not the top qualifier for the business end of the tournament.
Millbrook representative Jeong, 16, posted rounds of 75 and 70 to finish 1-over-par in qualifying, one shot clear of Choi.
The highlight of Jeong’s qualifying efforts was a hole-in-one on the fourth hole in her second round.
She then bowled through the matchplay stage of the championship with wins over Emma Bei Lyu (6&5), Rebekah Blackwell-Chin (1-up), Gabriela He (4&2) and Ha Young Park (2&1) to reach the final.
Jeong’s star continues to rise after she represented New Zealand at the R&A Junior Open in Scotland earlier this year.
Another to watch on the southern(ish) scene is Clearwater golfer Cooper Moore.
He won the men’s title at the New Zealand Amateur with a storming comeback in the final.
Moore, 16, who won the Otago strokeplay last summer, was 3-down against Robby Turnbull (Remuera) in the afternoon before winning the 30th, 31st, 33rd and 34th holes.
Turnbull won the 35th, sending the final to the 36th hole all square. Turnbull landed in a bunker and Moore dropped a perfect approach shot to a metre from the pin for the winning putt.
While Turnbull had qualified No 1 with a score of 7-under, Moore went through tied for 14th after blowing out to 2-over.
Otago golfer Ricky Kang performed well in qualifying, shooting rounds of 68 and 71 to finish at 3-under, tied for fourth.
Provincial team-mates Parker Aluesi and Will McLauchlan tied for 20th at 5-over.
Kang beat Luke Kidd 3&2 in the first round of matchplay but fell 5&4 to Max Clarke in the second, while Aluesi was knocked out in the first round.
McLauchlan went on a nice run, winning his first two matches before losing 2&1 to Turnbull in the quarterfinals.
