Wellington: Veteran Springboks lock Victor Matfield has marked All Blacks backrower Kieran Read as a key figure in their “do-or-die” Rugby Championship clash in Wellington on Saturday.

South Africa need to pull off their first win against the All Blacks on New Zealand soil since 2009 if they are to have any chance of stopping them claiming the southern hemisphere championship for a third successive year.

“It’s a big game for us, a do-or-die game for us in this championship,” Matfield, the most-capped Springbok with 114 Tests to his name, said on Friday as he described the All Blacks as “the biggest challenge out there”.

The 37-year-old lock said one of the reasons he came out of retirement this year was the attraction of once again facing the reigning world champions, along with having a crack at another World Cup next year.

And Matfield sees the biggest threat from the All Blacks as coming from number eight Read, last year’s world player of the year, and his influence at the line-out.

“Kieran Read makes a huge difference,” he said, noting how Read’s development as an international has coincided with the rapid improvement of the All Blacks’ line-out.

Although the loss of Whitelock would have an impact, “they’ve still got Kieran Read there,” Matfield said.

“If Kieran Read wasn’t there it might be a different fish, but with him still there they will still be very strong.”

After falling to Australia 24-23 in Perth last week, the Springboks go into this Test as underdogs, although Matfield said they had high expectations of themselves and recognised the value of toppling the hosts a year out from the World Cup.

“We want to win this game, we want to win the championship,” he said.

“The more you can beat the All Blacks the better because you might face them in a World Cup and we know they are going to the World Cup as favourites.

“There are a few [Springboks] who haven’t beaten them so it will be great if we can get in their heads that they’re not invincible.”

The All Blacks and Springboks have faced each other in 87 Tests, with the New Zealanders winning 50 and losing 34, while three were drawn.
