The 22-year old recently signed a deal with the Jets after a season with North Queensland Fury and after breaking his leg in late January, is back on track a lot earlier than first expected.
Brockie will remain in Townsville to get himself fit before the All Whites' training camp in Auckland later this month and says he is in constant contact with national team officials as he continues his rehabilitation.
"I talked to (head coach) Ricki Herbert the other day and he wants me at the camp if I'm able to participate fully," Brockie said.
"That's my aim. I've got six to eight training sessions [in Townsville] before then. That should be enough to build my fitness and confidence before the training camp.
"Because I had surgery, I went straight into a moon boot rather than a cast, so I was able to take it off and do some exercises to get some strength back into my ankle.
"I was off the crutches after five weeks and I've been back running."
Brockie said his decision to join the Jets was mainly due to the uncertainty surrounding the Fury doubled with the fact that he feels Newcastle coach Branko Culina is the man to help further his career.
"I like it here in Townsville and they're a great bunch of lads, but I had to look after myself at the end of the day," he added.
"Newcastle are a pretty consistent side and they were A-League champions one year.
"Branko told me his plans and what he hoped to achieve with me over the next two years. I think he's the right coach to take me the next step in my career.
"He wants me to play wide in midfield. He thinks that's my best position and I think so too, although I am versatile and can play at the top [striker] if I'm needed and I've played a little behind the front two as well."
