It was New Zealand's second-largest one-day loss in terms of runs.
The West Indies won the first match of the series by two wickets, while New Zealand won the third by 159 runs and fourth by 158 runs. The second was abandoned due to rain.
The West Indies have been beset by injuries and the unavailability of key players throughout the tour, hurting their performance in the last two matches.
But they were determined to end the one-day series on a high note, battering the New Zealand attack in an innings that included 41 fours and nine sixes.
The West Indies bowlers, led by Jason Holder, Bravo and Miller, then exposed the frailty of the New Zealand batsmen when they are placed under consistent pressure.
"We came into this game with our backs against the wall and we came away with a big win,'' Bravo said.
"We really played hard to represent our country and represent ourselves. Johnson Charles and Powell have had a difficult time but it was important that the management team, myself and the coaches backed them.
"They've done great things for us in the past and it was important they believed in themselves.''
Edwards reached his century from only 90 balls in 139 minutes, while Bravo posted his more swiftly, from 79 balls in 106 minutes. The West Indies reached 300 after only 43.4 overs against a helpless New Zealand attack.
"It was a terrible day for us but credit to Dwayne and his boys, they came out today and produced a performance we knew they were capable of,'' New Zealand spinner Nathan McCullum said.
"We weren't able to stay with them. I thought Kieran at the start, then Kirk and Dwayne, the innings that they played were world class."
