Maiden centuries from Devon Conway and Daryl Mitchell set up New Zealand's crushing 164-run win over Bangladesh in the third ODI in Wellington on Friday, giving the hosts a series clean sweep.
Conway blasted 126 from 110 balls and Mitchell finished on 100 not out after New Zealand won the toss and elected to bat, making 318-6.
Bangladesh were never in the hunt for the 319 target, all out for 154 after 42.4 overs, with Mahmudullah's unbeaten 76 the only highlight as eight batsmen failed to reach double figures.
Jimmy Neesham and Matt Henry did the damage for New Zealand with the ball, taking 5-27 and 4-27 respectively.
Paceman Rubel Hossain was the pick of the Bangladesh bowlers, with 3-70, but the tourists' attack struggled on a green Basin Reserve wicket.
"We were just not good enough," Bangladesh skipper Tamim Iqbal said.
"No doubt the Black Caps played unbelievably well but we didn't perform. Sometimes the small things can hurt you, the [dropped] catches and the run-out chances."
Conway capitalised on the tourists' woes and his century was just reward for the South Africa-born batsman, who has been in outstanding form since he was first selected for the Blacks Caps late last year.
His performances include 72 in the second Bangladesh ODI and an unbeaten 99 when he was left stranded in a Twenty20 match against Australia last month.
Mitchell looked like he would suffer a similar fate in Wellington before scrambling home to bring up his century on the last ball of the innings as wicketkeeper Mushfiqur Rahim tried to stump him.
"I was just trying to swing as hard as I could, there were a few played and missed in there," Mitchell said.
"I'll take them any way they come. It's just nice to get the job done."
