"I want to make the most of every opportunity and if I think too far ahead it's all going to go horrendously wrong."
Ronchi, who has hit 13 hundreds and averages 38 in 79 first-class games, works in the here and now, and comes firmly from the one step at a time school. Focus on the next game, the next innings and go from there.
"That's the way I've always played cricket. I'm more worried about now than the future. If I do that, my head's in the wrong space."
Ronchi, born in Dannevirke but raised in Western Australia, is acknowledged as the country's best pure wicketkeeper. However BJ Watling is making a good fist of the test job, which narrows Ronchi's international options by one.
His first opportunity, against England and at the Champions Trophy in England in May-June didn't go well. But he made progress on the trip to Sri Lanka early in November.
Ronchi doesn't have a specific keeping mentor. It used to be Australian great Adam Gilchrist, Ronchi's state and club mate. There are others to make the odd suggestion, but he feels he has a good handle on his glovework.
"Now I feel when things are not quite right, when my feet aren't moving well, when I'm not catching the ball things like that.
"So I know when to make adjustments and what I need work on."
Ronchi has been moved about the order for New Zealand but believes where he is now, around No6 or 7, is his best role. He naturally scores rapidly, although knows there are times he may be better off dialling the speed back for a better return.
The word from coach Mike Hesson and captain Brendon McCullum is play his own game, keep doing what he's doing, not worry if things aren't going right and trust in his talent.
And as for the World Cup, that's for contemplating closer to the time.
"All sorts of thing would be going through my brain I don't need to think about," Ronchi said. "If I keep it really simple, then everything's sweet."
