The day started as a two horse race with Luck starting the final round seven shots behind, but with the 54 hole leader Brett Coletta making two double bogeys half way through the round, the door opened for his fellow Australian who pounced and won the tournament by one shot after a 72 hole birdie.
This also left the door slightly ajar for New Zealand's Luke Toomey, who was making a run on his own with an impressive round of six under (66).
This rocketed him up the leader board to finish in third alone in what has been a successful week for the 23-year-old.
"I'm just bloody stoked and it's satisfying to know the hard work is starting to trend nicely," said Toomey.
The Waikato number one kept the faith after holing a 35-foot putt for birdie on 12 and for the first time this week carded a bogey free round which included six birdies.
Although he left his run slightly late, this positive result will do him the world of good.
"I came here with the intention to do something special but I probably didn't make those birdies quick enough. I'm not going to think of the what-ifs, I'm just proud of what I did achieve today."
Toomey's finish matched Ben Campbell in 2011 as the best by a New Zealander in the tournament's seven-year history.
Campbell finished third behind Japan's Hideki Matsuyama.
Nick Voke was next best Kiwi in 11th place on three-over.
Tournament debutant Daniel Hillier finished tied for 15th on six-over, followed by Nick Coxon (13-over) and Ryan Chisnall (16-over).
All players showed character and fight throughout the week, but what was most impressive was the way they conducted themselves off the course.
They were a hit with many, especially all the local caddies.
It was a special week for the large New Zealand contingent inside and outside the ropes as they prepare to host this amazing event in 2017 at Royal Wellington.
To have the world's best amateurs and the world's most powerful golfing bodies in our back yard will be something very special.
