New Zealand are monitoring Trent Boult's fitness ahead of the first Test against an unchanged Australia side at Perth Stadium.
Boult has been troubled by a side strain and could miss the day-night contest, which starts on Thursday.
Batsman Ross Taylor (thumb) and all-rounder Colin de Grandhomme (abdominal muscle) are set to feature in the first of three Tests between the trans-Tasman rivals.
Black Caps captain Kane Williamson said of Boult's availability on the eve of the match: "We're going to have another look today before deciding anything for Thursday.
"I think you look at it as a long-term decision in terms of this whole series. He has tracked really nicely and felt really good on Tuesday."
Lockie Ferguson could make his debut in the longest format after the paceman missed out in a 1-0 win over England.
"It’s exciting we've got Lockie in our squad to consider him," said Williamson. "It's exciting to have a guy in our camp who can bowl at that speed."
Australia have gone with the same side that completed a whitewash of Pakistan.
"We've been playing some really good cricket, happy with the way it's going so we're trying to get a consistent team together and as I touched on after Adelaide, the great thing is we've got guys that are performing really well," Australia skipper Tim Paine said.
"That's what we wanted so we're going to go with the same team."
