The Taradale Primary School Year 6 pupil picked up a club at the age of 4 with encouragement from his six handicapper father, Vinnie Swanwick.
Two years later he was ready to push his boundaries.
"I went to Sharpies [Driving Range in Hastings] where they had an open day," says the youngster who at 7 won his maiden junior competition.
While meeting people and having fun are on his agenda, Swanwick practises three to four times a week in hour-long spells.
His father, and professional Andrew Henare, help hone his skills.
That consistency is prevalent in his junior rounds during the club champs for the member of the Golf Hawke's Bay Junior Academy.
"My goal is to become a professional golfer. I want to play in the par 3 Masters with my dad in America when I'm about 22 years old," he says.
Another Bay junior academy member, Cosmo Graham, was runner-up in the gross division of the Wairarapa Open.
Graham, who competed in the recent Maori Open tourney in Taupo, carded 75, 82, 84, 81.
Vinnie Swanwick says a contingent of Bay amateurs competed in Masterton so such trips away from home offer the youngsters the opportunity to build a rapport.
"They mingle with each other and it's good because they come from different clubs."
For the record, Zac Swanwick, who sometimes eats good food, won a Nutribullet last weekend and will, no doubt, put it to good use.
In the Wairarapa Open section, Brad Truesdale, of Dannevirke, was runner-up.
Fellow Bay senior men's rep, Dallas Williams, was fifth.
Guy Harrison, of Napier GC, was the last day's stableford winner among the intermediate men.
