The two sides meet in the World Cup semi-finals this weekend and Read is anticipating a stern test from the Springboks, despite the fact New Zealand have dominated South Africa in recent years with 10 wins in the last 12 fixtures.
"History has shown that prior form means nothing when it comes to a finals game. We've got to turn up and certainly take lessons from the games we've played against them in the past," Read is quoted as saying by stuff.co.nz.
"We know their style. They know us. So it's all part of turning up and playing well. They'll be as confident as we are."
The All Blacks sealed their place in the last four by thrashing France 62-13 in the quarter-finals, while South Africa fought hard to claim a 23-19 victory over Wales.
