New Zealand crushed Sri Lanka by 423 runs at the second Test in Christchurch to acquire the series 1-0.
SriLanka began the final afternoon on 231-6 chasing an implausible 660, but brushed within 14 balls.
Angelo Mathews, that retired hurt by a hamstring injury on afternoon, could not resume his innings as Sri Lanka were bowled out to 236.
A fourth successive series win lifted newzealand in to third party at the International Cricket Council ranks.
“That is a pretty cool thing to reach,” said captain Kane Williamson.
Even though Sri Lanka skipper Dinesh Chandimal and Kusal Mendis, together with 56 and 67 respectively, allowed Sri Lanka to elongate the match to some fifth day, no other batsman passed 2-2 as NeiL Wagner finished with 4-48.
Mathews has been dominated from the three-match one-day show starting about 3 January and the Twenty20 international on 11 January.
“Angelo had a scan last night, and it is really a standard two hamstring strain. The physio said he is outside for a month,” said Chandimal.
The all rounder, that has been affected with injuries in the past couple of years, are also an uncertainty for its two-Test show in Australia which begins on 24 January.
