Gavet moved to New Zealand at a young age and played his junior football for rugby union club Ponsonby and the Richmond Bulldogs before being signed by the New Zealand Warriors. Gavet played for the Warriors NYC team in 2009, scoring 2 tries in 18 matches[4] before moving on to the Warriors' NSW Cup reserve-grade team, the Auckland Vulcans, in 2010. In 2011, Gavet was named Prop of the Year in NSW Cup and signed a 2-year contract with the Canterbury-Bankstown Bulldogs after playing them in the 2011 NSW Cup Grand Final.[5]
In his NRL debut game for the club, he was put on report late in the match for a shoulder charge and was served a three-game suspension. While serving the suspension, he ruptured his anterior cruciate ligament (ACL) at training, ruling him out for the rest of the season.[15] On 20 October 2015, he was granted release from the final year of his Broncos contract.[16]
New Zealand Warriors
In January 2016, Gavet returned to the New Zealand Warriors on a trial basis,[17] before signing a 1-year contract starting effective immediately on 22 February.[18]
