Scorchers star Tye is the senior member of an Australian T20 pace attack missing Test quicks Mitchell Starc, Pat Cummins and Josh Hazlewood.
The West Australian has played seven T20 internationals, Kane Richardson three, Billy Stanlake one and Ben Dwarshuis is uncapped.
"Richo and I are probably both senior bowlers in this group, but Billy has shown he can do it, Ben Dwarshuis has had an unbelievable Big Bash," Tye said.
"The confidence within the group is high."
New Zealand are being careful not to underestimate the Australian attack.
"While Starc, Cummins and Hazlewood are world-class bowlers, these guys are picked for a reason," NZ batsman Martin Guptill said.
"We can't take anyone lightly because anyone can have their day and rip through a batting line-up.
"It's about us coming out there and doing our scouting and making sure that we're ready for what they've got in their arsenal."
The Black Caps are also wary of Australia's batting power, with noted hitter Chris Lynn coming back from injury.
"Lynn has obviously taken the shorter formats by storm over the last couple of years," paceman Tim Southee said.
"As bowlers we've got plans that we'll look to use against certain players and then also you've got to back your experience and sum up the conditions."
Tye says Lynn appears in good touch.
"He's hitting them pretty well, he's looking as good as ever I reckon, ready to take down some bowlers," Tye said.
He was convinced Hobart Hurricanes power-hitter D'Arcy Short would make a successful transition to international cricket if given a debut during the series.
"He's got such a cool calm head on his shoulders," Tye said.
