Kane Williamson's dismissal has been the major talking point from a rain-affected start to the second test against Pakistan at Seddon Park.

Forced into the action early, Williamson had constructed a sound second-wicket partnership with Jeet Raval.

The Black Caps skipper had compiled 13 until a Sohail Khan gem snuck through the No.3's defence as he shaped to drive in the 15th over.

Pakistan appealed and reviewed the 'not out' decision, which was subsequently reversed by television umpire Ian Gould.

Gould presumably saw something beyond the capabilities of the footage. Snicko showed the noise of the ball grazing near Williamson's upper right forearm, but Hotspot indicated no incriminating contact with the glove or bat.

There did not appear to be conclusive evidence to overturn the on-field ruling, but Gould's decision sent Williamson on his way, and ensured more debate about the processes of the Decision Review system.
