A dire New Zealand batting capitulation opened the door for the West Indies to win the first cricket Test in Antigua by nine wickets.
A draw was the likely outcome when the final day began but the Black Caps collapsed from 3-199 to be all out for 272, losing their last seven wickets for just 73 runs inside 32 overs.
Needing 102 in 46 overs to win the first of the two-Test series, the hosts strolled to victory.
They reached 1-102 in 19.3 overs, losing just Kieran Powell for 30 off the bowling of Doug Bracewell.
Fellow opener Chris Gayle, who scored 150 in the first innings, raced to an unbeaten 64 which included eight fours and two sixes.
His comfortable innings was a far cry from New Zealand's labouring effort as West Indies pace bowler Kemar Roach claimed four of the seven wickets to fall on the fifth day to finish with innings figures of 5-60.
Aside from 30 from wicketkeeper Kruger van Wyk, none of the New Zealand batsmen produced an innings of note although fellow South Africa-born teammate Neil Wagner lasted 103 balls for his 13.
It was Wagner's dismissal shortly after lunch that sparked a collapse, with specialist batsmen Kane Williamson and Dean Brownlie failing to reach double figures.
The result was another low point in a tour that has seen New Zealand well beaten in both the Twenty20 and one-day international series.
The second Test starts at Kingston on Thursday.
