New Zealand lost openers Tom Latham (0) and Jeet Raval (1) in the first 10 balls of the innings before Starc returned for his second spell and dismissed skipper Kane Williamson (34) to end a fighting 76-run stand for the third wicket with Ross Taylor (66 not out).
A couple of overs later, Starc removed Henry Nicholls (7) and nightwatchman Neil Wagner (0) off success deliveries. Taylor and B.J. Watling, who was yet to score off eight balls, will resume with New Zealand needing another 108 runs to avoid the threat of being asked to follow-on.
Just when the experienced Williamson and Taylor looked like steering the tourists to respectability, Starc forced Williamson into a false shot and Steve Smith took a breathtaking one-handed catch at second slip as he flung, full length, to his right.
Later, Starc had Nicholls caught down the leg side, and then forced Wagner to play on to his own stumps. He was on a hat trick with the first ball of his next over, only to be denied by Taylor. Starc, who hit a quick 30 runs earlier in the afternoon, extracted steep bounce and took a return catch off Latham’s leading edge on the fifth ball of the innings.
The left-arm paceman had figures of 4-31 off 11 overs. When Josh Hazlewood took the wicket of Raval, who was bowled off his pads, it left New Zealand teetering on 2-1 and the tourists continued to struggle even when Hazlewood left the field two balls into his second over with a suspected strained left hamstring. He will undergo scans overnight.
New Zealand toiled for 10 hours and 146.2 overs in hot conditions over two days to finally dismiss Australia by tea on the second day, with swing bowler Tim Southee (4-93) and Wagner (4-92) the pick of the New Zealand bowlers.
No. 3 batsman Marnus Labuschagne top-scored with 143 and Travis Head hit an aggressive 56. Captain Tim Paine was the last batsman to fall, caught down the legside by wicketkeeper Watling off Southee for 39 runs cobbled together over three hours, off 105 balls.
Ravel, a part-time legspinner, gave New Zealand something to smile about in the afternoon when he bowled Pat Cummins (20) around his legs to end a 38-run, seventh-wicket stand with Paine after the pair resumed 337-6 after the lunch break.
Runs were hard to come by in the middle session against disciplined line-and-length bowling by the New Zealand bowlers until Starc arrived at the crease. He took to spinners Mitchell Santner and Raval, smashing a six and three fours. Starc was dropped by Raval at mid-off on 27 as the left-hander tried to hit Southee over the top.
Two overs later, though, trying to repeat the shot again off Southee, Starc holed out to Williamson, who took a brilliant catch running backward toward the boundary. It triggered a lower-order collapse, with Australia losing three wickets in nine balls.
In the first session, Labuschagne narrowly missed his third consecutive 150 when he was bowled around his legs by Wagner. He hit a six and 18 boundaries in his 240-ball innings over six hours. New Zealand was playing without fast bowler Lockie Ferguson, who was ruled out of the test with a strained calf muscle in his right leg sustained on the opening afternoon.
