Daryl Mitchell and Glenn Phillips combined to steer New Zealand to a seven-wicket win over Pakistan in the NZ vs PAK 4th T20I in Christchurch on Friday and place them on the verge of a series clean sweep.

The Black Caps pair scored unbeaten half-centuries in a 139-run stand as the home side reached 159-3 in the 19th over in response to Pakistan`s 158-5. They were forced to mount a rearguard action after Pakistan captain Shaheen Shah Afridi knocked over New Zealand`s top order, reducing them to 3-20 in the third over.
