Tim Paine has termed his side’s clinical performance as ‘teamwork’ following their fourth consecutive Test win this summer.
After hammering Pakistan convincingly in a two-Test series, they have now dominated New Zealand in the two Tests played so far.
A hundred from Travis Head in the first innings and clinical performances by Smith (85) and skipper Paine (79) ensured the home side were in a commanding position right from the start.
The pace trio of Pat Cummins, James Pattinson and Mitchell Starc followed up by off-spin of Nathan Lyon helped Australia dismiss New Zealand cheaply in both innings.
Paine, who called on other batters apart from Steven Smith to step up their game, said his side had now started to divide the load.
"I think it shows that we're starting to spread the load," he said.
"When we work together as a team and build pressure -- one day it's going to be Pat (Cummins), the next day it's going to be Nathan (Lyon), the next day it's going to be James Pattinson, another day it's going to be Mitchell Starc.
"We just keep driving that home to all our team.
"If we keep building pressure as a team we've got some absolute firepower and we know that all of them are going to have their day in the sun."
Paine said the same concept applied to the batting group as well, where it was important to work in partnerships.
"The same with the batting, trying to build partnerships, trying to take teams' bowlers really deep, make them bowl lots of overs," he said.
"At some stage we're all going to get a chance to score lots of runs as well."
Australia, who retained the urn in England this summer, have last Test of this summer against New Zealand at Sydney starting next week.
Paine said he wanted the same firepower for the Sydney Test despite getting an unassailable lead in the three-match Test series.
"We want to win every Test match, there's no doubt about that," he said.
"We know we've wrapped up the series here today, which was pleasing, but with the (ICC) Test match championship every Test is really important.
"So winning the series is almost less important until we wrap up next week hopefully with another good win."
