Highlights - NZ into semis as South Africa collapse
New Zealand's Kyle Mills and Daniel Vettori and South African Francois du Plessis have all been fined after an altercation in Friday's World Cup game.
Mills was docked 60% of his match fee for "inappropriate and deliberate physical contact between players".
He was also fined a further 60% by ICC referee Roshan Mahanama for conduct "contrary to the spirit of the game".
Vettori was fined a total of 90% for the same two offences, while du Plessis forfeited half of his match fee.
He was only charged with the more serious breach of the player's code of conduct.
Ironically, Mills has now been ruled out of the remainder of the World Cup through injury and will be replaced by Andy McKay, who is expected to join the team on Sunday.
The Auckland paceman strained his left quadricep during the group stage victory over Canada two weeks ago and was unable to play in Friday's shock quarter-final win by the Kiwis.
The incident occurred when Mills, who was acting as a drinks carrier, came on to the pitch at the end of the 28th over of the South African innings after AB de Villiers had been run out, leading to a confrontation between the two sets of players.
Mills pleaded not guilty at a full hearing chaired by Mahanama and attended by match umpires Aleem Dar, Rod Tucker, Kumar Dharmasena and Nigel Llong, who laid the charges.
Mahanama said: "It was a very important time of a crucial match for both sides but there is never any excuse for deliberate physical contact in international cricket.
"Vettori and Mills continued to act inappropriately and contrary to the spirit of the game throughout, hence the second charges were laid against them.
"In determining the punishment I have taken into consideration the fact that none of these players has previously been involved in similar breaches of the code."
Mills has a right of appeal against the findings, but must do so within 24 hours.
Black Caps skipper Vettori and du Plessis, meanwhile, both admitted the offences and accepted their fines without the need for separate hearings.
