Latham century helps New Zealand to sizeable lead
- Latham scores fourth test century
- New Zealand lead by 151 runs
- Williamson survives controversial TV call
Opener Martin Guptill was dismissed in the first session for 40, was caught in the gully to hand debutant Chamu Chibhabha a first test wicket.
Henry Nicholls was the fourth wicket to fall, caught behind by Chairi from a full delivery by Donald Tiripano.
Chairi was deputising for Regis Chakabva who was confined to bed on Friday with a high temperature.
The New Zealanders will look to bat through the third day after Williamson said his side would seek time at the crease to prepare for tougher series in South Africa and India over the next two months.
