The Kiwi international and Barnes have 10 goals each in the Premier League this season - Wood thinks he would add some value to the England squad.
"I am surprised yeah because he causes defences a hell of a lot of problems. He could do that on the international stage as well," Wood told the Lancashire Telegraph.
"I'd like to think he will get one very soon. He should have had one by now. He's a menace, causes a lot of problems. I'm just glad I don't have to defend against him.
"England don't have anyone like him, I think he would add value to the England squad, definitely.
"He's scoring goals but he also does well to get other people into positions to score some goals. He has an all round game, he works tirelessly on centre halves and doesn't give them a minute's peace."
