Younger brother Ethan, 15, has followed in Hamish's footsteps both as a player and umpire.
Ethan played for Tauranga Intermediate at AIMS, for Tauranga Boys' College and also Tauranga age group representative teams, but as an umpire he has gone one step further. He has umpired finals at national tournaments and at last year's AIMS hockey 6-aside final. Like Hamish he helped out at last week's AIMS Games.
Their youngest brother Dominic, 13, made it a real family occasion last week as he played for Tauranga Intermediate's hockey side, in his second and final year of competition.
It is not often that all three brothers appear at the same event so it was a proud week for the family.
As one brother prepares to move on, Dominic is already learning the craft of umpiring, so expect him to be a part of the AIMS Games in years to come.
So why do they do it? When asked, the reply from the three brothers was the same.
"Hockey has been good to us over the years. It's allowed us to travel and enjoy many good times and AIMS has always been one of those fun times. Now, it's all about giving back to the game. That's why we're doing this."
