The Highlanders resorted to hand signals at lineout time and hooker Andrew Hore says the All Blacks may consider similar measures to combat the noise generated in Dunedin's indoor stadium.

With an assured absence of wind or rain against the Springboks tonight, Hore isn't expecting any difficulty serving up straight throws for his lineout jumpers.

He's more concerned about ensuring his team-mates know they are the intended target.

“There's no excuse [for not throwing straight] because you can't blame the wind but one thing is the noise, getting used to that,” Hore said.

“Sometimes quick lineouts, those sorts of moves are hard to get through. With the Highlanders we played around with some hand signals so we'll see what happens.”

A sellout crowd, including a decent chunk of revved up university students in The Zoo, have built a reputation for generating plenty of volume and 29,000 will be at fever pitch for South Africa's first test at the city's new stadium.

“It's like that here and at the Chiefs, grounds that are built just for rugby, and I suppose it's like being over in South Africa as well where the crowd is right on top of you. But here seems to be particularly loud,” Hore said.

All Blacks captain Richie McCaw, who will play at the ground for the first time, said the issue of communication had been discussed and measures put in place.

“All the guys who have played here this year say whether it's full or not it's noisy regardless so it just means you have to get a bit closer to each other and make sure you are heard rather than expect to be heard,” McCaw said.

“But it's the same thing for both teams. The big thing is to make sure you don't feel like you are on your own out there. You have to get beside each other when there are breaks in play and make sure you get things dealt with.”

The All Blacks' lineout has been a major strength all season while the Springboks are without suspended lock Eben Etzebeth and injured first-choice hooker Bismarck du Plessis.
