The 31-year-old has been confirmed as the new head coach of the Otago Gold Rush, taking over from Todd Marshall.
That comes after a year as the side's assistant coach, alongside Dean Ruske, in which the side claimed the WBC title.
It is a long way from 14 years ago, when he began his coaching career with the Bayfield High School year 10 B boys' team.
He has lost count of the number of teams he has coached since then.
School teams have figured, as have a plethora of Otago age-group teams and several Andy Bay Falcons men's teams.
He notably head-coached the Otago men's team at the now-defunct NBC twice, as well as against the Southland Sharks this year.
Assistant coach roles with the Otago Nuggets and Mainland Eagles also proved valuable.
If that is not enough basketball, he has also spent the past eight years working as Basketball Otago's operations manager.
As he prepares to lead the Gold Rush in its title defence, he was glad to be an example that you did not have to be a high-level player to get a top coaching job.
''It shows anyone can do it,'' he said.
''It also highlights Basketball Otago and the level of coaching we have in Otago, the fact we can develop these younger coaches.
''We have done in the past and we've got a long line of great coaches come from Otago and it's just proof it can be anyone.''
Many from that long line of coaches have led the Gold Rush over the years, with plenty of success. The team has won three WBC titles in the past eight seasons - including 2018 - and garnered a reputation as a top side.
Building on that, with a long-term focus, was key for Brockbank.
''The main thing for me is to help carry on the reputation of the Gold Rush as being a successful group.
''Continuing to grow the foundation that Todd [Marshall] and Dean [Ruske] and Brent [Matehaere] and JP [John Paul] and the other coaches have built on. There's no real tangible goal right now; that'll come later.
''Everyone talks championships. Is that a default goal? Maybe.
''But it's more of a long-term thing and we're just trying to build on that foundation and continue to be the team they have in the past.''
He was set to begin meeting players this week.
While there was no official word on who would be playing, he expected the core of last season's champion side would return.
