New Zealand 431 & 267-3 dec (Latham 109no) beat
Sri Lanka 294 & 282 (Chandimal 58) by 122 runs
First Test, Dunedin, day five
A clinical performance from the New Zealand bowlers ended Sri Lankan resistance on day five, dismissing them for 282 in the final innings and secured a 122-run victory for the Black Caps in the first Test in Dunedin.
It took New Zealand just 45 overs on the final day to dismiss the seven remaining Sri Lankan batsmen and to take an an unassailable 1-0 lead in the series.
Sri Lanka started the day at 109 for three, needing another 296 to win the game. Dinesh Chandimal (58) was dealing in boundaries as he brought up his second half-century in the game off 90 deliveries.
Angelo Mathews (25) was looking at ease in handling the New Zealand bowlers as he brought up the 50-run stand with Chandimal with a boundary to deep fine leg.
That's when Neil Wagner (2-56) was at his best with a fiery spell of reverse swing. The left-arm-pacer castled Mathews when he tried to leave a full length delivery, but the ball ricocheted off his pads and on to the stumps.
New Zealand seized on the opportunity as Mitchell Santner (2-53) had Chandimal trapped lbw to reduce Sri Lanka to 165 for five.
Kithuruwan Vithanage (38) decided to play aggressively as he got stuck into Santner, hitting him for a six and four and followed it with another couple of boundaries from Wagner in the next over.
Milinda Siriwardana (29) got his first boundary when he lofted Wagner to long leg for a six following which the new ball was taken by New Zealand.
Tim Southee (3-52) made the new ball count immediately as he dismissed Vithanage lbw on the stroke of lunch and Sri Lanka ended the session at 224 for six.
Trent Boult (2-58) got his first wicket when Rangana Herath (6) edged one to Martin Guptill in the slips.
Siriwardana was Boult's second victim as he found Brendon McCullum in the covers. Sri Lanka were eventually bundled out for 282 as New Zealand took an unassailable lead of 1-0 in the series with the 122-run win.
Southee picked up three wickets for New Zealand while Wagner, Boult and Santner managed two wickets apiece.
Guptill was named as the man of the match for his knock of 156 in the first innings.
The second and final Test will be played in Hamilton from 18th December.
