New Zealand were made to sweat before sealing a 2-0 whitewash series win over Zimbabwe in the final Twenty20 international at Seddon Park.
The Black Caps, chasing 201 for victory in Hamilton, were indebted to half-centuries from James Franklin (60) and Rob Nicol (56) and a superb five-ball cameo from Kane Williamson as they crossed the line with five wickets and two balls to spare.
Requiring 18 runs for victory with only seven balls remaining, Williamson struck a boundary from the final ball of the penultimate over before launching Shingi Masakadza for four, six and four to win the game in style.
The defeat was tough on Zimbabwe, who had earlier amassed 200-2 thanks to a swashbuckling unbeaten 75 from captain Brendan Taylor from only 43 balls.
Hamilton Masakadza and Stuart Matsikenyeri got Zimbabwe off to a blistering start with a stand of 76 in seven overs before the latter departed for 32, lifting Ronnie Hira to Tim Southee at long-off.
Masakadza reached a stunning 26-ball half-century with a six off Andy Ellis but slowed down thereafter and fell for 62 from 42, with three fours and four sixes, when he hoisted Michael Bates to Colin de Grandhomme.
Elton Chigumbura hit three fours in one Kyle Mills over and Taylor then reached 50 with a six off Bates from the 31st ball he faced as Zimbabwe piled on the runs.
Taylor then added two fours in Southee's last over but Zimbabwe could only take five from the final six balls, bowled by Mills, which also saw Chigumbura (29no) dropped by Franklin.
Openers Nicol and Franklin then got New Zealand on track with a century stand in 10 overs before Nicol, having hit four fours and four sixes in an innings of 56 from 37, skied Chigumbura to Keegan Meth at deep cover.
Franklin kept the Black Caps up with the rate before he was superbly run out from the boundary by Meth for 60, also made from 37 balls with three fours and five sixes.
Brendon McCullum added 38 from 24 but he and brother Nathan successively holed out off Kyle Jarvis, leaving Williamson as the key man.
A boundary meant 14 were needed from the last over and after Ellis squirted a single to deep mid-wicket, Williamson crashed Shingi Masakadza for four, six and four to win the game with two balls to spare. The 21-year-old finished 20 not out from five balls, four of which went to the fence.
Zimbabwe will therefore return home having been defeated in every match of their tour after the Kiwis won the one-off Test by an innings, the three one-day internationals by wide margins and then the two T20Is.
