The New Zealand goal poacher, who is nicknamed Sniper, joined United on a season long loan deal from Mamelodi Sundowns in a deal that was finalised on the eve of the Premier Soccer League's transfer deadline day.
The 31-year-old former SuperSport United ace is excited about his move to United and says there will be more happy days in his career now that he has joined the KwaZulu-Natal based club.
"It's very exciting to be here," Brockie told the media at his unveiling.
"It's no secret that it's been long waiting at Sundowns (not getting game time).
"But I always have a smile on my face whether in good or bad times but the smile is going to be bigger now that I am going to play constant football and be getting back to doing what I love most."
Brokie will also be reuniting with Team of Choice mentor coach Eric Tinkler - someone he worked with while they both were at SuperSport.
He will also be joining hands with fellow countryman Daniel Morgan, who was signed in the off season.
"It's always easier to join a new club where you know some familiar faces," Brockie added. "I worked with coach Tinkler at SuperSport and I know how professional he is. And the nice thing is that there's a Kiwi (Morgan) at the club."
Brockie was handed the number 10 jersey by the club and says he was looking forward to getting amongst the goals again.
"I know the expectations are very high because I scored many goals when I arrived in South Africa before I join Sundowns. Now it's my responsibility to prove that I can still score goals," he concluded.
Brockie is expected to make his debut for United when the club travel to Pretoria to take on the Brazilians in an Absa Premiership clash after the current FIFA break.
