Martin Guptill's golden run of form continued with a century which lifted New Zealand to a 36-run win over Sri Lanka to clinch the five-match one-day series 3-1.
Guptill made 102 from 109 balls — his 10th one-day international century — to steer New Zealand to 294 for 5 as it batted first after losing the toss.
Sri Lanka's hopes of a successful run chase soon evaporated when they staggered to 3 for 33 and were bowled out for 258.
Fast bowler Matt Henry took 5-40, snaring the top-order wickets of Danushka Gunathilaka and Lahiru Thirimanne to destabilize the Sri Lanka innings, then returning to snuff out any chance of a tail-end rally.
