The West Indies staggered to lunch without further damage after a Trent Boult-inspired New Zealand enforced the follow-on on the third morning of the second Test in Wellington.
Left-arm seamer Boult turned the Basin Reserve Test on its head with a supreme display of swing bowling to claim six wickets and dismiss the tourists for 193.
Trailing by 248 runs, they were asked to bat again by New Zealand skipper Brendon McCullum and negotiated the new ball to be 0-45.
Openers Kieran Powell (23no) and Kirk Edwards (17no) were largely untroubled although play was halted for 15 minutes late in the session for treatment on the right ankle of Powell – injured when he retreated from an aborted single.
They will resume still facing a deficit of 203 and a similar mountain to the one they scaled in last week’s first Test in Dunedin.
Trailing by 396 at University Oval, they followed on midway through day three and managed to force an unlikely draw.
To repeat that effort, they must see off the threat of Boult, who scythed through the middle and lower order on Friday morning.
The 24-year-old snared five wickets 15 balls to finish with career-best figures of 6-40 as the tourists crumbled in the face of his pacy inswingers.
Boult appeared virtually unplayable as the West Indies lost six wickets for 35 runs in a disastrous 12.5-over block.
He had Narsingh Deonarine caught at first slip by a juggling Ross Taylor for 22 before removing the other overnight batsman, Marlon Samuels, for 60 when his flash at a wide ball produced an inside edge.
The last four West Indies batsmen were all clean bowled for ducks, including three in the space of four balls from Boult.
Shane Shillingford departed for a golden duck while Darren Sammy and Tino Best both survived two balls before being skittled by Boult’s movement.
