Gemming said she was honoured and accepted the award on behalf of "the many volunteers that run our sport in New Zealand".
As a child, Gemming played many sports "but hockey was the one that really caught me".
"So I've played from a junior level right up to a senior level but it was probably coaching which became my passion."
Coaching was rewarding and it was particularly heartening to see young local players evolve into New Zealand representatives on the world stage, she said.
In her earlier coaching years, Gemming managed a team of under-13 Tauranga boys.
"It's a wonderful age group to work with because they are so enthusiastic and want to absorb everything. In 1996 we won The Hatch Cup [National Under 13 Boys Tournament] and that was our first for Tauranga. Since then we have consistently been in the top 10 in New Zealand," she said.
"But it wasn't about me, it was about those groups of young boys that you work with. And what I love about it is some of those boys, Andy Hayward and Steven Graham , are now Black Sticks."
These days, Gemming is focusing on the New Zealand Masters teams. As she talks to the Bay of Plenty Times, she packs her bags to join the national women's team who are training over the long weekend for next month's World Cup held in Spain.
As much as she loved the international competition, it was seeing new generations of aspiring hockey players coming through in Tauranga that she was especially fond of.
"It's rewarding watching them grow and then seeing them get involved with their children," she said.
For Gemming, coaching was something "I'm really thrilled to have given back with".
