Wilson was a roving marshall accompanying a group of golfers on Friday, which included World Amateur golf champion Danny Lee, Nationwide tour Panama Open winner Vance Veasey, and 2009 NZ PGA winner Steve Alker.
They were on the 10th hole when Wilson said he noticed Alker's caddy, Shane McInnes, having some difficulty getting around the course.
"You could see he was hurting, He was limping heaps and really struggling,"McInnes was experiencing a bad case of shin splints.
"I asked him if he was all right and if maybe he wanted me to carry the bag," Wilson said.
After a brief discussion between Alker and McInnes, a marshall was summoned on the 11th hole.
McInnes retired hurt and the 24-year-old Wilson stepped into the caddy's role.
"It was surreal," he said.
"I literally got a chill up my spine as I pulled the caddy bib on. It was fantastic."
Wilson finished the remaining holes, from 11 through to 18, carrying Alker's clubs.
He had one of the best imaginable views on the course as Alker came home to card nine under and briefly hold the lead.
For Wilson, a Mainpower linesman from Rangiora, it was an experience he said he would never forget.
"I had met Steve the week before after he won the NZ PGA [at Clearwater]. I was a volunteer there, too.
He brought the winner's cup back to the volunteers' barbecue afterward and met a whole lot of us,"The pair chatted as they walked the fairways together, he said.
"He was really talkative and friendly. He even remembered who I was, once I told him about the PGA barbecue."
However, the chit-chat stopped whenever it was time for Alker to concentrate on his game.
"There was no way I was going to make any [shot] suggestions. He asked for a club and I just gave it to him," Wilson said.
The Rangiora Golf Club member has been getting a lot of ribbing from the other volunteers for his star turn.
Yesterday, he was back in his usual role of roving marshall, in which he accompanied the final tee pairing and third round leaders Grant Waite (NZL) and Martin Piller (USA).
