They are part of the sport's large volunteer force which puts in huge miles to judge at and help the competitions, symbolised by the 370km-each-way journeys to Wairoa for Fagan and fellow King Country judges Ian Buchanan and Tod Oliver.
It's not like a trip down to the local park to referee a game of rugby or umpire a game of cricket, as Fagan explained: "To get near a third of our judges involved in one weekend is quite unique".
He first qualified and judged while still competing in the early 2000s.
"I do a bit to keep in touch" said Fagan ahead of his first trip to Wairoa since his competition days, when he was usually unable to compete in the northern Hawke's Bay show because it clashed with major events in Southland.
