AFP, HAMILTON: A brutal spell from Neil Wagner, including three wickets and a broken arm, led New Zealand to a comprehensive victory over the West Indies in Hamilton on Tuesday.

The tourists, set a target of 444, folded to be nine for 203 at tea on day four with Sunil Ambris retired hurt and unable to continue batting.

The 240-run victory saw a dominant New Zealand wrap up the series 2-0 after winning the first Test by an innings.

The hostile Wagner accounted for most of the damage in the second innings in Hamilton with his short-ball barrage targeting the body.

Ambris was taken to hospital after a vicious blow to the forearm. He tried to struggle on and reached five before trudging from the field.

It ended a tough Test baptism for Ambris who was twice dismissed in his first three innings by treading on his stumps.

Shai Hope, on 23, also required on-field medical attention after being on the forearm by a rising Wagner delivery.

When play resumed he attempted an ambitious hook at another short delivery and was caught by Colin de Grandhomme at long leg.

Shane Dowrich lasted two balls after Ambris left when he fended a Wagner bouncer to Henry Nicholls at short leg.
