New Zealand have won the coin toss ahead of their World Cup semi-final against South Africa and will change in Twickenham's home dressing room.
Team managers from the four remaining sides in this year's Rugby World Cup gathered in the tunnel at Twickenham on Monday to determine changing room allocation, team shirts and arrival times ahead of the semi-finals.
South Africa, who defeated Wales 23-19 in a hard-fought battle at Twickenham in the first quarter-final, will face reigning champions New Zealand on Saturday, who scored nine tries on their way to a 62-13 victory over France in Cardiff.
The All Blacks, who won the coin toss and become Team A for their semi-final, chose changing room two at Twickenham, traditionally used by the home team, while South Africa will occupy changing room one.
Argentina, who booked their place in the semi-finals with a 43-20 win over Ireland, will take on Australia in the second knockout game on Sunday at 16:00. The Wallabies earnt a last-minute 35-34 win over Scotland in Sunday's dramatic quarter-final at Twickenham.
In the second coin toss of the afternoon, the Pumas were victorious, becoming Team A and also elected for the larger of the changing rooms, number two. Australia, as they did in their quarter-final, will set up in changing room one and hope their luck continues.
With no clashes between the kits in either semi-final, all four sides will line-up in their traditional team colours.
