The Warriors will welcome Zebre to Scotstoun knowing a win guarantees they will host their first ever play-off game, having already secured a RaboDirect Pro12 top-four berth.
Zebre, 11th in the table, are currently tied on points with fellow Italian side Treviso but have won their last two games over Edinburgh and Ospreys, which is already a club record.
And 26-year-old Nakarawa, who arrived in Glasgow from the Fiji Barbarians last August, believes the Italian outfit will prove to be formidable opponents this weekend.
"Saturday night is all about winning and forgetting about the play-offs," Nakarawa told the Glasgow Evening Times.
"First and foremost, we have a Zebre side who are coming to Scotstoun on the back of two superb victories - over Ospreys and Edinburgh.
"They are also doing everything they can to finish above Treviso and secure Italy's European slot.
"So they have an awful lot to play for, are very much in form and have no pressure or expectancy on them to win.
"That makes it vital for us to focus on our game and make sure we deliver the best performance we can at Scotstoun and really give the Glasgow fans something to feed off."
