"It's a great feeling," he said of his 13 wickets in three games. "But it always comes in partnerships.
"Even though I was fortunate to get rewards, the guy at the other end was going at three an over. If you're keeping pressure on at both ends, something's got to give."
The Bay Oval pitch wasn't easy for batsmen, especially when they were starting out and getting a feel for the conditions.
However, Henry felt once they were "in", it became easier to accumulate runs on the large outfield. Quality fielding became an important factor, and New Zealand are a slick outfit right now.
"That's something we pride ourselves on," Henry said. "One thing you can control is your fielding and it's something we work hard on and like to keep a high standard."
Sri Lankan batsman Lahiru Thirimanne admitted his team had misread the pitch and in hindsight would have played another spinner instead of a seamer.
"But it didn't matter because we could still have won the match," Thirimanne said.
"The wicket played really well. Up front we lost a couple of wickets, which was a big disadvantage. Angelo batted really well but we just couldn't do it in the end."
