"Something inappropriate was said. When you are bringing people's families or wives into it it's unacceptable," Paine said.
Video of the ugly incident has been leaked in dribs and drabs this week. The International Cricket Council (ICC) is understood to now be probing that aspect of the saga, after match referee Jeff Crowe finalised punishments for both players.
South Africa's Independent Media released CCTV images during the test, which showed the final stages of the scrap as Paine, Steve Smith and Usman Khawaja usher Warner into Australia's changerooms.
Footage then came to light of Warner calling Quinton de Kock a "f***** sook" as the players headed off the ground at tea.
Warner has accepted a level-two charge of bringing the game into disrepute. Australia's vice-captain was fined $13,500 and given three demerit points, meaning he will cop an automatic suspension for any further misdeeds in the next two years.
South Africa unsuccessfully contested de Kock's level-one charge for his role in the fracas, arguing provocation at today's hearing.
Crowe ruled the original punishment should stand, with de Kock docked 25 per cent of his match fee and slapped with one demerit point.
