Cricket: Williamson scores big, Southee takes a wicket as Black Caps dominate England
Williamson's 156 was the 33rd time he had scored a Test century and the seventh time he had passed the milestone at Seddon Park. He brought up his century with a six down the ground. Rachin Ravindra started the delayed first session of the day alongside Williamson, but fell just short of a milestone of his own.
