The second Test between the two nations began on Friday at St George's Park in Port Elizabeth and fans attending the match are preparing by making Sonny Bill Williams masks to taunt Warner, according to the Stuff website.

All Blacks star Williams and Warner's now wife, Candice, were involved in a toilet tryst in the bathroom of a Sydney hotel in 2007. Another patron took a photo of the pair under the toilet cubicle door, and the images went viral.

It is understood that Proteas wicketkeeper Quinton de Kock's retort to Warner's sledging was to mention Williams and his brief relationship with Warner's wife.

Warner was fined 75 percent of his match fee for the incident, in which he had to be held back by team-mates as the teams returned to the changing rooms during tea on Day 4 of the first Test in Durban.

Australia went on to win that opening Test at Kingsmead by 118 runs.
