Lockie Ferguson could make his international debut against Australia on Sunday after impressing New Zealand captain Kane Williamson.
The 25-year-old fast bowler earned his place in the touring party for the three game one-day international series on the back of some strong first-class showings with Auckland.
His pace and aggression provide a different option for the Black Caps and Williamson could be ready to unleash his new speedster following an eye-catching session in the nets in Sydney.
"He [Ferguson] sent a couple of messages at training," Williamson told a media conference.
"He bowled really nicely so we'll have to wait and see. He bowls quick and runs in and bumped me a few times which was great.
"It's what you want to face and it's fantastic preparation. The Australians will do the same. He has a one in 14 chance [of playing], I suppose."
Williamson will assess the state of the wicket at the Sydney Cricket Ground before confirming his team, with a little bit of grass boosting Ferguson's debut chances.
"We want to have another look at the surface tomorrow," Williamson added. "There's a little bit of uncertainty about what the surface might do.
"It has spun here in the past. It looks a good surface, it's quite hard, they might have rolled in perhaps some old grass clippings to get a little bit more grass on it, maybe to add a bit of pace."
Whoever is selected by the Black Caps will be expected to hit the ground running as the tourists look to give themselves the upper hand in the opener.
"Australia are a very good team, we know that," the skipper said. "But the focus is for us to play our best cricket and if we do that we know we can beat anyone.
"It's important to do that [in Sydney] to give ourselves the best chance in this series."
