They will be hard pressed to halt the rampant world champions at North Habour Stadium, where lock Retallick nevertheless expects a typically tough contest.
“We all know the way the South Africans play,” Retallick told a news conference.
“We’ve seen the last couple of weeks how physical they’ve been, especially up front. As always, they’re big boys and they like to come at you.
“Every Test is special, but from what we’ve seen so far in the Rugby Championship, they’ve had two great wins over Argentina and they’ll be a little bit frustrated with the draw against Australia in Perth.
“They’ll be coming here with a bit of anger, and with the skill and physicality they’re playing with, I’m sure it’s going to be a good spectacle.”
Centre Crotty added: “We expect a massive challenge, and a huge, physical Test match.
“The history and the rivalry of the two nations builds it up a bit more.
“It doesn’t get any bigger than a Test against South Africa at home, and it’s a challenge I’m sure will excite the lads.”
