He is the second marquee player to be missing from the Wellington Hurricanes after All Blacks fullback Beauden Barrett transferred to the Auckland Blues.
Savea, a finalist for the world player of the year, revealed the extent of the knee injury in an Instagram post when he said he could be sidelined for up to six months.
"Thought I'd let you guys know that I'll be getting surgery on my knee that I injured in the semi-final," Savea said.
"Unfortunately will be out for 5-6 months so will miss the majority of the Super Rugby season with my Canes brothers.
