New Zealand's hopes of claiming a first Test win on Australian soil since 1985 soared on Saturday as the tourists grabbed a 153-run lead at the end of a dramatic second day's play in the second Test.
After skittling Australia for 136, New Zealand made 139 for three in their second innings with skipper Ross Taylor set to resume on Sunday on 42 alongside Kane Williamson (34).
With the lively greentop pitch ruthlessly punishing batting errors and rewarding good bowling, 23 wickets had fallen in just over five sessions of the test and the first-innings 56 from New Zealand's Dean Brownlie was the only batting tally of note.
Earlier, it looked like Australia might even struggle to beat the 47 they made against South Africa last month as the New Zealand bowlers ripped through their top and middle orders.
Chris Martin celebrated his 37th birthday with 3-46, Doug Bracewell grabbed 3-20 and debutant Trent Boult 3-29 as the New Zealand quicks made the most of the movement offered by the wicket and gave the Black Caps a real chance of winning their first test in Australia in 26 years. A stand of 56 for the eighth wicket from Peter Siddle (36) and James Pattinson (17), however, rescued the Australians from 75 for seven and ensured they would at least better their lowest score of 103 against New Zealand.
Injured Vettori out
Daniel Vettori will be out for up to a month with a hamstring injury. Scans confirmed his injury, which he aggravated before the start of the Test, giving seamer Trent Boult the chance to make his Test debut.
