The West Indies collapsed after lunch to trail New Zealand by 396 runs in the first Test in Dunedin.
The tourists lost five wickets for 54 runs after the resumption to be dismissed for 213 in reply to the Blacks Caps’ 609-9 declared and New Zealand skipper Brendon McCullum quickly enforced the follow-on.
Trent Boult struck in the third over after the break to remove Denesh Ramdin and then Shivnarine Chanderpaul in the space of three overs. The end came quickly despite some lusty blows from injured captain Darren Sammy.
Ish Sodhi claimed his first two wickets on home soil and an Aaron Redmond run out did the rest as the tourists fell apart.
But the New Zealand performance was overshadowed somewhat by revelations that three former NZ players were being investigated by the International Cricket Council for alleged match-fixing.
The tourists had resumed after lunch on 159-5 but Boult produced an inspired spell to eke out Ramdin and then the key wicket of Chanderpaul.
Ramdin gloved one behind before Chanderpaul shouldered arms and was caught in front lbw for 76. He referred the decision by Paul Reiffel upstairs but the ball was adjudged to have been clipping the top of middle stump.
Leg-spinner Sodhi bowled a googly to get through Shane Shillingford before some smart work from Redmond caught Tino Best short of his ground.
Sodhi had his eighth Test wicket to trap Shannon Gabriel lbw for a first ball duck and McCullum wasted little time in asking them to bat again with his bowlers sending down only 38.1 overs to wrap up the innings that resumed the day on 67-2.
Before lunch Tim Southee struck three times in a little over an hour to ram home New Zealand’s advantage.
Southee, extracting some life from a benign pitch, removed Darren Bravo, Marlon Samuels and Narsingh Deonarine in a devastating eight-over spell to reduce the West Indies to 106-5 under a blue sky in Dunedin.
He almost had another wicket, but BJ Watling failed to hold onto a tough chance down legside when Ramdin had yet to get off the mark.
Chanderpaul brought up his 62nd half-century after having passed 11,000 Test runs in the previous over before lunch, but perished to Boult when he inexplicably opted not to play a shot.
Southee ended with 4-52 with new-ball partner Boult grabbing 3-40 and Sodhi 2-63.
