Phoenix head coach Ricki Herbert hailed the 23-year old’s "important" signing as to provide cover, and competition, for the central defensive pairing of Andrew Durante and Ben Sigmund.

“Michael is a big, strong, quick defender who has impressed me when I’ve had him in All Whites squads,” Herbert said.

“He has been playing in a good league and I’m confident he will be quickly up to speed with the A-League.”

Boxall said he was “very excited” to be joining Phoenix.

“I’ve heard what a close-knit squad the club has, and I already know a handful of the lads through the All Whites, so I’m sure I will quickly settle down there,” Boxall said from Vancouver.

“New Zealand has come a long way on the professional football front thanks to Phoenix and I’m grateful to get the chance to play for Ricki and the club.”

After playing his early football in New Zealand with Central United, Three Kings United and Ellerslie, Boxall spent three years in the United States with the University of California Santa Barbara Gauchos.

In 2011 he was selected first overall in the MLS Supplemental Draft by Vancouver Whitecaps, but after being part of the starting line up early on, he found himself on the sidelines.

“Vancouver is a great spot to live, but the football has been a bit disappointing in the last few months,” Boxall said.

“I was out of favour with the coach and while I tried to do all the right things it didn’t make any difference.

“When it gets like that, it is time to move on and fortunately Phoenix were keen to have me.

“I’m not sure when I will be in Wellington as I have a few things to sort out over here, but so far as I am concerned, the sooner the better.”
