Borren (Otago) finished the event two under to be seven shots ahead of Cromwell schoolboy Inia Logan (16) with four other senior players a further shot back tied on six-over-par 290.
With Duncan Croudis joining the professional ranks and Brent McEwan and Chris Snow retiring from all representative golf, it was pleasing to see Ryan Bellamy (St Clair), Brandon Hodgson (Otago) and Sungwoo Han (Queenstown) all tied with Southland's Jeremy Hall on 290.
One of the outstanding performances of the weekend came from 14-year-old St Hilda Collegiate golfer Annabel Evans, who won the women's event by an impressive 23-shot margin.
Evans (Port Chalmers) carded 78, 76, 76 and 79 for a 309 total, one of the best women's scores in the event in recent years.
Queenstown's Simon Boland won the masters (over 40) event in a close fought battle with Kyle Geary (Chisholm Links) and Michael Wray (Island Park) tied one shot back.
Borren took the first round lead with a birdie and two bogeys on his front nine but fought back with three birdies coming home.
This gave him a two shot buffer from Bellamy and Han, with Logan, Hall and Daniel Elder (Otago) a further shot back on 72.
He followed this up with a one over par 72 to be three shots ahead of Hall and Logan with Han a further shot back.
Brandon Hodgson (Otago) and Bellamy were five shots from the lead while Terry Kim (Wakatipu Junior) was two further shots back.
Borren saved his best for yesterday morning, when he shot a 68 to go six ahead of Hall with the final round to play while Han and Logan were tied a further shot back.
