Brendon McCullum, Martin Guptill and Kane Williamson - New Zealand's likely top three for Tuesday - all played in that test and some scars may still remain.
The Black Caps were also exposed by the electric pace and movement of Australian left-armer Mitchell Starc when he took 6-28 during last month's Pool A thriller at Eden Park when New Zealand escaped with a one-wicket win.
Starc skittled the New Zealanders after they built up for the World Cup with games against Sri Lanka and Pakistan, who rarely tested them with the new ball.
Tahir, however, will be South Africa's semifinal wildcard. The leg-spinner bagged 4-26 in the Proteas' quarter-final win over Sri Lanka.
Quality leg-spin bowling is rarely seen on the international stage and Tahir has taken 70 wickets in 37 one-day internationals at 19.94 after making his debut for South Africa in 2011.
After New Zealand racked up 393-6 against the West Indies in Wellington yesterday, there is little reason to think their confidence wouldn't be sky-high but they will know a tougher test awaits.
