McKenzie backed up yesterday's commanding performance to claim the Jack Harris Cup by two strokes over Scott Laycock, while Stephen Dartnall, Matthew Griffin and John Wade rounded out the top five.
Despite getting off to a tough start with a bogey on the first, McKenzie's game came together when it counted to claim the first PGA Tour of Australasia tournament of the year.
"It's been hard work for a while. It's been a long time coming," said McKenzie who has competed on the PGA Tour of Australasia since 1990.
"Words are eluding me now. I actually lost a Victorian PGA by missing a short putt about 20 years ago, so it's nice to actually win."
After his round an emotional McKenzie thanked his wife and parents for their support throughout his career and also made special mention of his very good friend Ramsay McMaster who passed away unexpectedly just over a year ago.
Following his passing, McKenzie said it took him a long time to even want to go near a golf course, but says he's back enjoying golf again, and will always look to Ramsay for inspiration.
"Ramsay was one of my biggest supporters," said McKenzie of his friend who was renowned as one of the world's leading golf specific physiotherapists.
"He'd call at three in the morning just to give me a rev up and just to say to keep going in only a way that Ramsay knows how. It has and will take me a long time to get over it."
At the presentation ceremony he added, "I wish he was here to see this..and hopefully he did."
McKenzie says he will play the upcoming McMaster Memorial Golf Day which will take place on February 1st at Victoria Golf Club.
For the win, McKenzie received the trophy from six-time Victorian PGA Champion and PGA Life Member Jack Harris, along with a prize cheque for $19,500.

The only hole-in-one of the day belonged to Rohan Blizard who used his 8 iron to ace the137m 8th hole.
Blizard's ace was the fourth hole in one of the week, and the second during competition rounds.
At the post-tournament presentation Geoff Stewart, Southern Division Executive Officer of the PGA thanked Forest Resort Creswick for hosting another successful tournament.
"I'd like to thank everyone involved at Forest Resort Creswick and also the volunteers who have given up their time this week. The players have thoroughly enjoyed the hospitality and we look forward to seeing you all again in 2014," he said.
The PGA Tour of Australasia now heads to Heritage Golf and Country Club for the inaugural Lexus of Blackburn Heritage Classic to be played from 24 - 27 January.
