"For me it's just trying to take the opportunity, there's always going to be others [potential wicket keepers] floating around," he said during day one of his debut against Wellington in the capital.
While Wellington had sent Northern Districts in to bat, giving Christopherson a relaxed start to his first-class career, he said he would rather have got out in the middle.
"It's an opportunity. I was pretty keen to get the gloves on, to be honest, and shake out a few nerves. It's a flat track so wasn't a bad toss to lose. It would have been good to have a run."
Christopherson's Northland coach, Stephen Cunis, commented that the young man would have been feeling a mixture of nervous and excited energy yesterday when he claimed his first cap - a memory Cunis can still relate to, 15 years after he made his first-class debut for Canterbury against Central Districts.
"I was seriously anxious," Cunis recalled of his debut in 1998.
"I was nervous and excited and when you put the two together that's an anxious feeling.
"Both Neal [Parlane] and I have said to him it doesn't matter if you are playing for your club, or association, or whoever, you've just got to make sure you do the basics."
Cunis said that the opportunity presented to Christopherson was one the talented cricketer deserved and had been awaiting.
Since moving to Northland from Auckland after being shoulder-tapped by former first-class cricketer - and now Northland Cricket's competitions manager - Parlane, Christopherson has cut down his work hours to allow him to chase the dream of being a fulltime cricketer.
"He just works so bloody hard ... he never says die," Cunis remarked of him. "He's changed a lot of things with fulltime work, committing to Kaipara Flats, and bloody deserves it when he gets the chance.
"I hope he enjoys the challenges now and puts the pressure on. He's a good bugger, really.
"He's played bloody well for [Northland]. Without a doubt I think he's the best keeper in Northern Districts, other than BJ [Watling] - I don't really count him in that.
"I do think he's better than [incumbent back-up wicketkeeper] Cam Fletcher but Cam has better numbers in batting than Rory and that is what has kept him out of the team until now."
However, Christopherson has the chance now that contract back-up Fletcher is set to undergo surgery on a finger that never recovered after he hurt it in round three of the Plunket Shield. The surgery is likely to rule him out for the remainder of the summer.
