At the end of the NRL season, it was revealed Locke had been given permission to speak with rival clubs after the Kiwi outfit signed English superstar and fellow fullback Sam Tomkins.
Locke was given a deadline of October 15 to find a new team, but nothing materialised despite interest from several clubs.
“Next year is going to be a challenge for me, and I want to make it a challenge for him [Tomkins], too,” Locke said.
“If we’re both challenging each other, and that goes right across the team, just like we are here in Kiwis camp, you’ll get the best out of everyone.
“If I am doing everything right, then opportunities will come. In your league career, if you don’t want it, it’s easy to let go. It can all just fall apart like that and I’ve seen it happen with players I’ve played with.
“They have either lost interest in the game or just didn’t work hard. Having him [Tomkins] come to the club will probably make me want to work harder. I will look for that opportunity to either get re-signed or if it comes down to it, moving clubs. I’ll focus on 2014 first and see what challenges that brings.
“So it’s all up in the air for me and I’m just going to have to put my head down and make sure I’m doing everything right.”
