He paid testament to Gunn's good character and said his client should be considered for community work, which he already did.
''He's involved in every sort of community organisation you can be in in the Teviot Valley.
''He's salt of the Earth in terms of his involvement in the community.''
Judge Flatley said it did not make sense someone with Gunn's level of community involvement would ''act in this way''.
''I just don't get it,'' he said.
On the morning of May 2, the opening day of the duck shooting season, Gunn and a group of friends were duck shooting off a boat on the Clutha River near Butchers Pt when they spotted ducks and headed towards them, causing them to take flight.
Gunn fired six shots from a 12-gauge shotgun. But two women were walking on the track beside Lake Dunstan and were partially obscured.
One was struck by shotgun pellets in the right leg and the other was hit in the right breast and collarbone area, Judge Flatley said.
The pair received moderate injuries.
The victims called out and lay on the ground to avoid being shot again.
Realising what had happened, the group ''took off in a panic'' but later returned to check on the welfare of the women and apologise, he said.
When spoken to be police, Gunn did not offer any explanation of why he and his party decided to hunt in this manner.
Judge Flatley said he could find few similar cases when considering a sentence starting point but those he could had carried a sentence of between 13 and 18 months' jail.
Aggravating factors were that Gunn was in breach of Fish & Game New Zealand council rules, he had fled and did not go to police until after a media release about the shooting.
''This just seems to be a lack of judgment on your part for whatever reason; a moment of stupidity,'' he told Gunn.
However, given his high standing in the community, a sentence of community work was appropriate, albeit at a high level to reflect the potential seriousness of his actions, Judge Flatley said.
He sentenced Gunn to 300 hours community work with one year of supervision and ordered him to pay the $1000 he had offered to each to the two victims for emotional harm.
