Speaking to the media for the first time as a Wakefield player, Locke hailed his new teammates for their performance in Wednesday night’s 26-16 home win over Hull.
Wildcats hit back from 16-0 down to end a run of 16 successive Super League defeats and Locke - a 2013 World Cup finalist with New Zealand - said: “Everyone was disappointed with the way we started.
“We went into the changing sheds at half-time and reflected on it and moved on from it and came up with a good second half performance.
“It builds a bit more confidence. We have still got a few more games before the middle-eights and I think we can build from last night’s performance heading forward into the middle-eights.
“What we saw last night just goes to show what the team are capable of, getting wins like that and knowing we can play like that.
“The boys know what we can do, but we’ve got to concentrate game-by-game.”
Locke joined Wildcats last week after “resigning” from his Salford Red Devils contract.
“I love it here,” he said. “I felt welcome the day I stepped into the Wildcats.
“I am really happy here, I have found a place where I want to be and I want to play footy.
“It is all about being happy. That’s all I focus on.”
