West Indies captain Kieron Pollard said his team has not performed to international standards after New Zealand won the second Twenty20 by 72 runs on the back of a record century by Glenn Phillips.
New Zealand wrapped up the series at Mount Maunganui with a game in hand, after winning the opening match on Friday by five wickets.
Called up to the Twenty20 side in place of captain Kane Williamson who was rested, Phillips struck eight sixes and 10 fours on his way to 108 as New Zealand posted a mammoth 238-3 and then restricted the West Indies to 166-9.
After winning the toss and sending New Zealand into bat under overcast skies, Pollard believed the West Indies were in control when the Black Caps reached the halfway mark at 84-2.
"But between overs 10 to 15 we sort of lost it there," Pollard said.
"In terms of the energy and feel and erraticness in the field, that's not the standard that we want to set for ourselves, and not the standard anyone wants to see in international cricket.
"I think it's attitude and I think it's our mindset. If we had stayed in the contest a bit longer, try to limit the damage to 200, 190 or so, we'd have been for the challenge. But we were behind the eight ball after that 10th over and it just went pear-shaped from there."
Newcomer Phillips, on the other hand, was over the moon.
"You never know when the next opportunity is going to come and I came into this going 'let's go in as hard as I possibly can. I know I can do it'," Phillips said.
The 23-year-old, who was born in South Africa but moved to New Zealand at the age of five, took just 46 deliveries to reach his century, the 10th fastest in Twenty20 Internationals and one ball faster than the previous New Zealand record held by Colin Munro.
Phillips plays in the Caribbean in the New Zealand off-season and said familiarity with the West Indies attack was a big help.
"Definitely, that has a lot to do with how I performed out here. You go in with more confidence against guys that you've played well against before," said Phillips.
