The 26-year-old made his first professional debut in February in which he defeated Richard Tutaki by knock out and later on was Clint Foai by another knock out on April 13.
Fa’s third winning over the weekend was made while he was participating in the Royal Rampage which is New Zealand’s First WBC World Title Championship to be held in the country.
After the fight Fa took to Facebook to thank all his “family, friends and supporters”.
“Thanks to the best corner team that we have. You guys are awesome!! Thank you to my wife and kids for constant love and support. Loved every minute in the ring tonight”, he said.
Fa claimed a bronze medal for Tonga at the Delhi XIX Commonwealth Games in 2010.
In 2012 Boxing New Zealand’s hopes of sending Joseph Parker to the Olympics was on the ropes when he was beaten by Fa in the opening session of the Oceania qualifying tournament in Canberra.
Fa also won two previous bouts against Parker before the Canberra qualifying tournament.
Parker now holds the titles of the WBO Oriental, OPBF and WBC Eurasia Pacific Boxing Council regional heavyweight titles.
