Murdoch said she after a couple of near misses during the past four months she had allowed herself to wonder if an ace was possible.
The 59-year-old has always had a passion for golf, even though she took up the sport later down the track after having become a cricketer in her teenage years.
"I've always wanted to play [golf] all my life but, when I was younger, girls didn't play it."
She had a couple of lessons with Peter Cassidy and then just went out and learned the game by repetition, finding out that no two rounds were similar, even on the same course.
"I play with some really awesome people who have been a great help to me men and women," Murdoch said.
The two most recent aces in Wanganui had been recorded in November and December by Blue Davies and Ray Mosen, also Tawhero club members, during the Business House League at the Belmont Links.
