Mr Alex "immediately stood up" after being shot, and yelled to Scott for help.
The summary said Scott then rushed to Mr Alex, who was bleeding profusely from an open shoulder wound, and administered "life-saving first aid".
Police arrived soon after and found Scott in a "distressed state".
Scott accepts he did not identify or clarify where Mr Alex was when he took the ill-fated shot. In fact, he did not know where the teenager was when he pulled the trigger.
The summary also explained why police did not try to revoke Scott's firearms licence after the shooting.
Scott is a representative shooter whose ambition is to compete for New Zealand at Commonwealth and Olympic level.
"This is combined with his commercial requirement to carry and use firearms in the course of his business. Subsequently no order is sought regarding the destruction of firearms or revocation of his current firearms licence status."
