The quality and class of Kwasnik was a major reason for the New Zealand club chasing him and the added firepower he will provide is a massive advantage for the Phoenix.
A one-year deal has been agreed by both parties and chief executive Tony Pignata was delighted with the new addition. Speaking to tvnz.co.nz website, he said, "He's (Kwasnik) a proven campaigner who has played in two A-League Grand Finals and has been with the Mariners for three years. He's a proven goal scorer.
"Adam will complement the team well and fill that crucial striking role."
