Some of France's top players have been left at home, having met the FFR's 2000-minute mark of rugby played during the season.
Robertson said, "One thing with the French, they've got depth.
"He's [coach Fabien Galthie] created depth over the last six years that he's had the squad, and all those young, exciting players that come through. French rugby is in good stead, in a good position.
"And this is when they're probably at their most dangerous, when they're underestimated.
"It's been a while since we've had success so our focus is on ourselves."
They came close last year, losing by one point in Paris.
Robertson said in their off-season review that the game featured because the All Blacks had given themselves so many opportunities to win.
"We felt we probably had our best two weeks with the Irish and the French, and we probably didn't get the result we deserved. Sometimes you don't get that in Test matches and a couple of bounces of the ball didn't go our way."
Robertson said France comes to New Zealand with the ability to play and without too much weight of expectation on their shoulders. That made them dangerous.
"The biggest thing is we respect them with our preparation and understand those strengths, but also with the ability that we've been together for a year, our cohesion's high and we trust ourselves. They will respect this team."
Having seen the effect of refereeing emphasis on more ball-in-play time, Robertson is keen for the All Blacks to take advantage.
"We want to play fast. We think the game's in a great place for us, quick scrums, quick lineouts, these taps. Our skill set trends to us playing fast and keep creating, so that's what we'll push all week."
Discipline is an area the All Blacks need to improve, as it cost them last year. It is something they need to understand as individuals and as a team.
Robertson said loosehead prop Tamaiti Williams would be out for six to eight weeks after surgery. Robertson wouldn't be drawn on his decision to play the Super Rugby Pacific final, after he suffered the injury in the quarterfinal.
George Bower has been called in as his replacement. He was one of the tough calls made when he didn't make the squad, but the management is pleased to have him available.
With Ethan de Groot and Bower, there was experience in the role, while Ollie Norris was being given a chance in top company.
"That's why we picked him, to find out about him."
They would miss loose forward Wallace Sititi, who, while named, was forced to withdraw for surgery for an upper ankle injury.
"It's tough for Wally, but he's a great rehaber, He came back last time amazingly, and he will again."
