The 25-year-old Samoan-born star only moved to the Stade Marcel Michelin on a short-term deal earlier this season but he has made such a big impression that he has since signed a permanent deal to remain with last year's beaten finalists until 2017.
"I don't have any ambition to be a big name in the game," said Lee, who believes the power of the European game suits his style. "I just want to do my best and do everything I can to help Clermont to be at the very top.
"I went to my teammates and didn't hesitate in asking them for help when I moved here. I want to show that I can work very hard for this team.
"The way rugby is played in France suits me. There is a lot of forward play and I love the commitment of the guys in that area of the game.
"That suits me better than a game based on collective speed like you find in New Zealand. The game is not as fast as over here but it's more physical and I like that. I've found it a real pleasure to play so far."
Lee has featured in the last four Heineken Cup games for Vern Cotter's side, starting three times and scoring two tries as Clermont made the quarter-finals for the third year running.
The former Chiefs Super XV squad member and Counties Manukau regular has made 53 carries in those four appearances in Europe's top tournament and has missed just two tackles in 38 attempts.
