The Kiwi can play in the halves and at hooker. Smith has been linked with a move to St Helens.
But Wane has dismissed those rumours and believes competition for places is healthy.
“I’m happy with Matty, George, Sam, Jake and Micky – and the best will play,” he told Wigan Today.
“We are a club where – if you’re a player who doesn’t like competition – we’re not for you.
“I know there’s talk among fans and in the media, but the players all understand it and they like it.
“I want everyone to be under pressure – that’s what brings the best out of them.”
