Last year, she won a silver medal at national level in athletics and was in the winning Alhambra-Union women's rugby team.
Martin (16) enjoys both sports.
''One's winter and one's summer. I enjoy them both. It's good having rugby after a summer of athletics,'' she said.
''I make heaps of friends and like the competition in athletics and the physical side of rugby.''
She made a significant breakthrough last summer when she won a silver medal in the junior girls hammer throw at the New Zealand secondary schools athletics championships, at the Caledonian Ground.
It was a personal-best throw of 42.71m with the 3kg implement.
She felt the emotion of the occasion when standing on the podium to receive the medal.
''It was great to know that I had achieved what was a pretty big goal for me,'' Martin said.
Her goal is to reach the podium again when she competes in the senior girls hammer throw at the secondary schools championships in Hamilton in December.
Martin has been coached by Raylene Bates for the last three years.
''She has an enormous sporting talent,'' Bates said.
''If you tell her to do something she can think it through, visualise it and put it into practice.
''She has the amazing ability to think it, see it herself and feel it. A lot of young athletes can't do that.''
Bates said her best quality is ''that she is an extremely hard worker. It doesn't matter if it is rain, hail or snow, her mum and dad will have her down at training''.
''Her work ethic is amazing. That is why she succeeds.''
Martin also competes in the shot put and discus. At the South Island secondary school championships this year she was second in the intermediate girls hammer throw and won the shot put.
She was second five-eighth in the Alhambra-Union rugby team that won the premier title last year and teamed with Black Fern Kelly Brazier.
Martin was too young for the Otago Sprit representative team last year and was in the Otago sevens squad that is part of the wider New Zealand squad preparing for the Rio de Janeiro Olympics.
Martin lives on a lifestyle farm with horses, cows, sheep and dogs, near Waikouaiti.
Martin, who has two brothers and a sister, was born in Perth. Her parents were keen on sport. Mother Brigid played hockey and her father Neil played gridiron and Australian rules.
