The first Test between New Zealand and South Africa in Dunedin remains in the balance as Dean Elgar enjoyed another good day at the crease.
The left-hander racked up 140 in the first innings and added 89 in the second on Saturday as the Proteas opened up a 191-run lead over their hosts.
Elgar's 89 came off 249 deliveries, before he skied a Jeetan Patel delivery which was taken by Kane Williamson running to his right from mid-off.
Before that JP Duminy had been trapped by Neil Wagner for 39 while Faf du Plessis remains a danger after compiling an unbeaten 56.
At stumps, New Zealand had South Africa at 224-6 but with the prospect of a result threatened by forecast rain on the final day.
