"Yeah, I guess you could go that far. It's nothing I'm going to forget in a hurry."
Of his catch, from Corey Anderson's bowling, Boult was a bit bemused.
"I kind of threw my body up there and it literally went straight into my hands. I don't know how that happened, to be honest. But it was brilliant, if I can say that."
Tim Southee and Neil Wagner did their bit yesterday with strong spells after lunch, but this was Boult's test.
In the course of the match he jumped ahead of Dion Nash, Richard Collinge, Simon Doull, Chris Cairns and Frank Cameron in averages of those with 50 or more test wickets.
He chomped four runs off his average, which now sits at 26.92, with only Shane Bond (22.09), Richard Hadlee (22.29) and Bruce Taylor (26.60) ahead of him.
