"I thought in the last 30 minutes against Argentina last Saturday that we were reasonably close to getting a lot of things right," he said.
"We've been aggressive, which is pleasing, and we're trying to mix that with playing at intensity and speed and we're gradually getting that right.
"The pleasing thing was the way the players figured the game out as they went along in Wellington. I thought the two Aarons (halfback Smith and first five-eighth Cruden) settled into the decision-making role and did well after a difficult first half."
Dan Carter's calf strain is the only major injury in the All Blacks as they start their preparations in Dunedin.
"We've come through pretty well again, which is good," Foster said. "There was a lot of ice in the shed afterwards but I think we should have a full playing roster in the next couple of days."
Foster said the All Blacks were relishing playing their first test at the enclosed Forsyth Barr Stadium.
"It was unfortunate last weekend with the conditions in Wellington. We love playing there too but it's nice to have the surety of you game plan and to know conditions are not going to change.
"The team's very excited about it. We've watched a lot of Super rugby there and we can't wait."
Foster said that, while it was possible some fans had under-estimated Argentina, the All Blacks had not.
"The statistics were similar to our World Cup quarter-final against them. They take a long time to break down.
"South Africa offers a couple of different things.. You have to deal with the high ball and to focus on winning the collisions because you know they're going to come at you at 100mph.
"All Black v South Africa rivalry is legendary so we know it's going to be a ferocious battle and that we are really going to have to front up physically."
Foster described the test between the Springboks and Wallabies in Perth, won 26-19 by Australia, as "desperate."
"Both teams threw everything at it and it was tight right until the end. We expect nothing different on Saturday night. South Africa is coming off a draw and a loss and it is really important for them to get a win."
The All Blacks will train at Carisbrook on Tuesday morning.
