South African captain AB de Villiers has won the toss and elected to bowl in today\'s second one-day international against New Zealand in Napier. South Africa\'s Graeme Smith (arm injury) drops out of the team from the side who beat New Zealand by six wickets in Wellington in game one on Saturday and he has been replaced by Justin Ontong. New Zealand, who need to win to keep the three-match series alive, have named Nathan McCullum as their 12th man, which means Tarun Nethula and Andy McKay will play on the sun-drenched McLean Park wicket. Play is due to get underway at 2pm. New Zealand: Martin Guptill, Rob Nicol, Brendon McCullum (captain), Kane Williamson, Jesse Ryder, James Franklin, Andrew Ellis, Kyle Mills, Tim Southee, Tarun Nethula, Andy McKay; Nathan McCullum (12th man) South Africa: Hashim Amla, Justin Ontong, Jacques Kallis, AB de Villiers (captain), JP Duminy, Faf du Plessis, Albie Morkel, Robin Peterson, Dale Steyn, Morne Morkel, Lonwabo Tsotsobe; Johan Botha (12th man)
