Locke also opened up about his battle with depression and how he sought help from a church rehab centre.
He told Woman's Day: "I was very lonely, being in my own little bubble away from Chelsea and the team. I was going through a really bad patch. I'd go down every two weeks which would make me feel good, but when I was alone, I'd be going out drinking...my head was all over the place. I'd promised her I'd ease up on partying when we got married, but I didn't. "
Despite his battles, he told Woman's Day he was determined to change his life for the sake of his wife and three and a half year old son Louie.
Locke, who's now 27, played 88 games for the Warriors up until 2014, scoring 26 tries.
He represented New Zealand eight times, before spending two seasons in the UK Super League.
