The 22-year-old has returned stronger and fitter after a disappointing 2004, which saw him dropped by the Hurricanes and unable to retain his place in the All Blacks side.
But the burly wing is back to his best and challenging for a place in this year's New Zealand squad to face the British & Irish Lions.
He followed up a superb try against the Highlanders 10 days ago with three in the second half against the defending champions as the Hurricanes swept aside the Brumbies 49-37.
The second was easily the pick, as he beat three defenders to score in the left-hand corner.
"He can step off both feet, he can fend and go straight through you," Cooper told The Dominion Post.
"He has a lot of qualities, an arsenal if you like. It was just a matter of giving him space.
"He's the best line breaker in the world; it's about getting him quality ball. He can beat most people in the world one-on-one."
