New Zealand crush Sri Lanka by 423 runs in the second Test in Christchurch today.

Resuming at the overnight score of 231 for six on the 5th day today, Sri Lanka scored 236 for nine with the injured Angelo Mathews not returning to finish his innings.

Trent Boult and Neil Wagner mopped up the Srilankan innings in 14 balls today to take the last three wickets for a colossal 423-run victory.

The overwhelming victory gave New Zealand the series 1-0 after the first Test in Wellington was drawn.

The scores:
New Zealand 1st innings 178 and second innings 585-4 declared.
Sri Lanka 1st innings 104 and 2nd innings 236.
