A two-hour rain delay but no reduced overs in Kingston meant the game ticked over the five-hour mark as the Black Caps won by 13 runs.
Back were the likes of Kane Williamson, Devon Conway, Tim Southee and Trent Boult, while it was move aside Michael Bracewell and Mark Chapman who took their chances against Ireland, Scotland and Netherlands in the past month.
With the return of the veterans the Black Caps have signalled they are now in World Cup mode ahead of the event, which starts in Australia in October.
Martin Guptill and Devon Conway put on 62 for the first wicket before Guptill was out to a stunning one-handed catch by Shimron Hetmyer at deep point. A ball later Conway edged to keeper Devon Thomas and Odean Smith was on a hat-trick.
Kane Williamson and Glenn Phillips got New Zealand through to 95-2 before heavy rain forced them off the field.
Shortly after the return, Phillips fell for 17 before Williamson, who top-scored, and Daryl Mitchell put on 46 for the fourth wicket.
Mitchell hit one towering six down the ground off Obed McCoy before a faint edge the next ball for 16.
Williamson was then caught in the deep by Hayden Walsh Jr for 47 off 33 balls to give Smith his third wicket. Jimmy Neesham's 33 off 15 ensured the Black Caps set a strong total of 185 for five.
In their chase, regular wickets halted the West Indians with Shamarh Brooks (42 off 43) the only batsman in the top five hanging around longer than nine deliveries, although skipper Nicholas Pooran did briefly entertain with three boundaries in his eight ball stay.
Mitchell Santner (3-19) led the way for the tourists, his wickets including the key dismissals of Brooks and Pooran, while Boult, Southee, Lockie Ferguson and Ish Sodhi all took a wicket each.
Late hitting from Romario Shepherd (31 from 16) and Smith (27 off 12) at least made the margin of defeat more respectable.
