Making Mahoney's effort even more noteworthy is the fact she missed most of the Wairarapa-Bush club season through a calf injury and was understandably a "little unsure" of her readiness to step up to NPC level as a consequence.
"I guess it wasn't the ideal preparation but it all worked out well in the end."
Mahoney believes her experiences as a player have been a huge help to her in the refereeing ranks, particularly when it comes to visualising what teams are trying to do before they actually do it, but, at the same time, she has found there are major differences too.
"Refereeing is a lot about player management, you are out there to ensure the players are given a fair go and can enjoy the game so the quicker you get them on side the better for everyone. Communication is so important, if you get that right everything else pretty much falls into place."
Mahoney is also at pains to emphasise the "very valuable" support she has received from the refereeing hierarchy, both here in Wairarapa-Bush and the national body.
"The encouragement has been fantastic, I couldn't have asked for anything more," she said. "It hasn't all been me, that's for sure, there's been a heck of a lot of help along the way."
Meanwhile, Bay of Plenty referee Bree Johnson will control the match between the New Zealand Heartland XV and New Zealand Marist XV to be played at Memorial Park, Masterton, on Saturday, kicking off at 6pm. Assistant referees will be Alistair Payne and Chris Jefferies.
