The Hawks have sent pick 33, 61 and a future fourth round selection to the Power for Impey, while the Power have attached pick 67 along with the forward.
Impey, who played 75 games for the Power in his four seasons at the club, requested a trade just over a week ago, and went on to nominate Hawthorn on the eve of the trade period.
The move sees Hawthorn add more pace and talent to their forward line, while allowing the Power to boost their draft stocks.

“We are really pleased a deal could be reached with Port Adelaide and look forward to welcoming Jarman to the Hawks,” Hawthorn’s Recruiting and List Manager Graham Wright told hawthornfc.com.au.
“His outstanding speed and endurance will be a really valuable asset and his ability to play at both ends of the ground is a great advantage.
“Jarman is a competitive character, who goes hard at the footy, which makes him an exciting acquisition and a terrific addition to our list.
“At only 22 years of age, Jarman has plenty of football ahead of him and we can’t wait to see what he can produce in the brown and gold.”
For Port Adelaide, it continues quite a busy off-season for the club, in what is their third move of the Free Agency and Trade Period window.
