Ma, who arrived in Dunedin from China about 10 years ago, was part of a successful New Zealand side which journeyed to Melbourne for the Australian veterans table tennis championships.
Ma (50) won the over 50 years women's singles, the over 50 years women's doubles and the over 40 years women's teams event. She also won bronze medals in the over 50 years mixed doubles, the over 40 years women's doubles and the over 40 years women's singles.
She said the competition was tough. Ma came from the northeastern city of Liaoyang and started playing the game with her family when she was 8. But she stopped played for about 19 years and resumed only in 2005.
Playing three times a week helped her sharpen her play, as did having a table at home, she said.
