Munro will finish his referee development manager's role with New Zealand Rugby at the end of this week before taking a job with the Racing Integrity Unit.
It ends a career in refereeing which took Munro to the top of international rugby after he first picked up a whistle in 1996.
Munro has accepted an offer to become a stipendiary steward with the Racing Integrity Unit that will mean he will become a regular sight at southern race meetings.
Munro also has the advantage of having previous racing experience that started when he was growing up in Pleasant Point where there were plenty of horses nearby.
''There were horses around all of the time and then when I was old enough and earning enough it was on to ownership in all three codes.''
Munro did a two-year stint with the Judicial Control Authority and will be on the other side of the inquiry room presenting evidence, rather than considering it, at judicial hearings.
His experience as a referee and his former career in the police mean keeping racing participants on the right side of the rules should not be foreign to him.
''I did a couple of years with the JCA, which I enjoyed.
''I don't profess to know it all so I will take my time. I suppose with my refereeing and my police background, that side of it is fine. But I need to learn the game and the intricacies of it.''
Munro's current role involves talent-spotting and managing up-and-coming rugby referees.
''I'm basically talent-spotting and finding the next test referees from throughout New Zealand.''
''The biggest challenge is that people are getting younger and think it is a fulltime gig, but there are only seven fulltime referees out of about 1700 in New Zealand.
''So it is certainly the cream of the cream to get that far.
''That is the challenge, to find the right person with the right attributes that could handle the pressure of Twickenham or somewhere.''
Munro plans to keep an eye on the New Zealand rugby scene and its referees from afar following his official exit this week.
''Hopefully, I could help out if someone wanted some advice. I am there for it, but you have to move on.
''Like anything there are highs and lows, there have been some wonderful experiences around the world meeting some wonderful people and then decisions that you make sadly people hold you accountable and take it personally.''
Two looming departures meant the RIU was on the lookout for a new stipendiary steward.
Dunedin's Chris Boyd and Invercargill-based steward Liam Tidmarsh will both leave the organisation next month.
Tidmarsh is returning to his native Brisbane.
He has recently been the head steward at the majority of recent southern harness racing meetings.
Chief harness racing stipendiary steward Nick Ydgren decribed Tidmarsh's departure as a huge loss.
