No more Mr Nice Guy.
That's the inference to be drawn from Kyle Jamieson's refusal to bowl to his Royal Challengers Bangalore and India's skipper Virat Kohli with a Duke ball to help him prepare for the World Test Championship next month.
And not before time, you might say.
New Zealand has been guilty of tugging its forelock too often in the world game, especially to Australia and England. There are numerous examples, but too many to quote here.
But in taking his action, Jamieson told The Cricket Paper, he didn't mind being disliked for his chosen stance.
As the paper pointed out, he had good reason to flex his muscles. Six appearances for six wins with two Tests each against India, the West Indies and Pakistan for 36 wickets at 13.3 each, a bag of five and a batting average of 56.
"I have to pinch myself at how things have unfolded. I'm lucky to have come at a time when the Test group's been successful for such a long period and such established guys.
"I probably have gotten wickets off the back of some of the pressure they've built. On the surface level, it looks like I've done really well. It's certainly a credit to those guys for the way I've started my career. I definitely don't think those numbers are going to stay the whole time. If no one else had done it in world cricket before, I certainly don't think that'll be me," he said.
Ah, humility in the classic Kiwi style, but with just a little steel not too far from the surface, one suspects.
Jamieson's development has been a model of restraint – not pushed too far too early in his career.
"I wasn't through into it straight away. So, once I got to this level, I could just play. It certainly relaxes you in a way, and makes your job a little bit easier," he said.
Jamieson also explained his method, especially in not getting too excited searching for swing.
"I'm excited by the chance to see the ball move around corners.
"But, I'm mindful, of trying to move the ball two sets of stumps and then get caught on the bounce. We've seen the likes of Stuart Broad using more of a scrambled seam. I've been looking to try and play around with that and try to get a gauge of what's the most effective way to operate.
"I'm relishing the opportunity to be part of a UK tour. To have had the last 12 months I've had, and to be able to potentially play a Test at Lord's is certainly pressure special," he said.
