South Africa have won one and lost seven of the nine semi-finals they have played in all one-day international tournaments. The other was a tie, against Australia at the 1999 World Cup -- a result that saw them eliminated on lower Super Six table placing.

This will be the seventh World Cup meeting between these sides with the Black Caps having won four of the previous six encounters. The only one of these that was a knockout match however was New Zealand's win at the quarter-final stage at Dhaka in 2011.

Daniel Vettori needs one more wicket to become New Zealand's leading wicket taker in World Cup history; he is currently tied with Jacob Oram on 36.

South Africa have won three of their last four completed ODIs against New Zealand at Eden Park.

The Black Caps have lost the toss in the last 12 ODIs they have played at Eden Park and have been put into bat on nine of these occasions, winning just one of these nine (L5, T1, 2x N/R).

Seven players have hit three consecutive ODI centuries before, if Martin Guptill hits a ton in this match he will be the third Black Caps player to do so.

Two more runs will see Guptill become the first Kiwi to score 500+ runs in a single World Cup, Scott Styris hit 499 in 2007. He would become the eighth player from any nation to achieve the feat.

Brendon McCullum has the highest boundaries per ball faced rate (34%) at this tournament.

Imran Tahir has bowled more balls (404) than any other player at this tournament; he and Vettori are the joint top wicket taking spinners (both 15).

Farhaan Behardien has scored 74 runs off the 36 balls he has faced in the tournament; he has the lowest dot ball percentage of any player (11.1%).

Kane Williamson has scored 53 runs from 51 balls bowled by Morne Morkel in ODIs, never having been dismissed by the South African seamer.

Change Agent — Fickle weather

Auckland’s weather is notoriously changeable and unpredictable and forecasts for Tuesday, and for the reserve day on Wednesday, have fluctuated in recent days. By Monday the chance of rain had grown to 60 percent and the official forecast was for scattered showers. The forecast for the reserve day is more favourable with warm temperatures and no mention of rain. World Cup rules specify that every attempt must be made to complete at least a 20-overs contest if a match in the knockout rounds is affected by rain. The regulations allow for a game that has begun on a scheduled match day to be completed on the reserve day. If no play is possible on either day, the team that was ranked highest after pool play will progress. That means that New Zealand, unbeaten in Pool A, will advance if weather prevents the semifinal being completed.
