Leigh (33), a Dunedin police constable, is just four months away from the compulsory retirement age for an amateur boxer.
Leigh, who started serious boxing three years ago, is weighing up his options and will not make a decision on his future in the sport until after next month's South Island championships in Timaru.
His first serious bout was only two years ago, when he won the South Island novice title in the light- heavyweight division in Christchurch.
Last year, he was named the most scientific boxer in Otago and, earlier this month, he beat experienced Southland fighter Renata Karena in a closely fought bout in Gore and was named the most scientific boxer at the tournament.
"In boxing, you always have a lot of respect for an opponent who runs you close," Leigh said.
It was a slow start in boxing for Leigh, who has always been interested in martial arts.
He only decided to become a boxer after watching the Russell Crowe movie Cinderella Man three years ago.
"I like the mental discipline and fitness skills you develop through the sport," he said.
"It looks like a lonely pursuit but it is really a team sport because you rely on your sparring partners and trainers."
Leigh works hard under the direction of coach Eldon Clifton and has 10 training sessions each week- five in the ring and the other five running or cycling to keep the legs fit.
Leigh also enjoys adventure sports such as mountain biking, surfing and mountaineering, and has climbed in the European Alps.
