New Zealand won the toss and opted to bowl first in the second ODI of the tri-nation series being played at Gaddafi Stadium in Lahore on Monday.
The pitch is said to be a batting paradise and it looked the score will go beyond 300.
Kiwis captain Mitchell Santner said they wanted to make use of early moisture on the pitch. He added New Zealand has made one change to the team, replacing injured Ravidra with Devon Conway.
New Zealand had won the opening match of the triseries beating hosts Pakistan by 78 runs at the same venue.
South Africa are without seven top players in the tri-series because they were involved in a Twenty20 League back home.
The series comes on the eve of the Champions Trophy in Pakistan and Dubai.
New Zealand: 1 Devon Conway, 2 Will Young, 3 Kane Williamson, 4 Daryl Mitchell, 5 Tom Latham (wk), 6 Glenn Phillips, 7 Michael Bracewell, 8 Mitchell Santner (capt), 9 Ben Sears, 10 Matt Henry, 11 Will O’Rourke
South Africa: 1 Temba Bavuma (capt), 2 Matthew Breetzke, 3 Jason Smith, 4 Kyle Verreynne (wk), 5 Wiaan Mulder, 6 Mihlali Mpongwana, 7 Senuran Muthusamy, 8 Eathan Bosch, 9 Junior Dala, 10 Lungi Ngidi, 11
