The All Blacks outscored the Fijians in front of a large crowd at Snapdragon Stadium. The lower intensity of defence in contrast to the series against England meaning the backs were able to operate with a bit more attacking intent.
"It’s a balance of the both", Robertson said.
"We were a little bit more courageous in playing.
"We really focused on making sure we took those second test positives into this one, get the boys set early and take those opportunities.
"There was a lot of last-pass stuff, some called back by the ref, some of those didn’t stick. But what we created was exciting. We’re evolving."
The only drawback from the game was the early withdrawal of halfback Cortez Ratima due to a heavy landing on his head and failing the subsequent HIA.
Noah Hotham, on debut, took his place and played out the remaining hour of the test.
Ratima was in good spirits but would be following HIA protocols over the next couple of weeks, Robertson said.
He confirmed veteran halfback TJ Perenara was expected to be available for selection for the Rugby Championship, and the All Blacks would finalise their squad this Sunday.
First five Damian McKenzie impressed against Fiji after his performance in the second test against England at Eden Park.
"DMac’s starting to own the 10 jersey, ask and demand of others more. He kicked extremely well — six out of seven conversions, out of hand. He can grow, as we all can."
Anton Lienert-Brown and debutant Billy Proctor’s combination in the midfield worked well right from the opening kick-off.
Proctor was rewarded with a first-half try, after a strong season with the Hurricanes led to him being called up to the test side.
As for the occasion itself, Robertson was full of praise for the support both from the locals and travelling All Blacks fans.
"A lot of people came to be a part of it. The Americans put on some show, the stadium, the atmosphere.
"It was good to share that with the American public, the Kiwis that travelled and the passionate Fijian supporters. To showcase our beautiful game, when it’s played well, it can create an atmosphere like that."
It took less than 10 minutes before the All Blacks struck, McKenzie breaking the line and finding Beauden Barrett, who shifted it smartly to the left for Caleb Clarke to cut back and score.
The second came soon after on the back of a strong carry from Lienert-Brown with Ratima then sneaking over from the base for his first test try.
After finally building some phases, the Fijians got themselves on the board courtesy of a cross kick from Isaiah Armstrong-Ravula was snaffled by Semi Radradra and forced inside to Vilimoni Botitu.
Proctor was then the beneficiary of some more slick hands from the All Blacks backs.
With the All Blacks dominating the Fijian scrum, a free kick was awarded 5m out. It was taken quickly then Ardie Savea switched to the left and powered to the line.
The Fijians should have scored again when they surged up field with several strong runs, but Jiuta Wainiqolo spilled the ball while attempting to ground it in the tackle of McKenzie, and the All Blacks led 26-5 at halftime.
The All Blacks scored five minutes after the break as Savea led the surge and Sevu Reece muscled his way over in the right corner.
Clarke looked to have bagged his second as Reece broke from a ruck, but it was scrubbed after replays showed the gap was created through Scott Barrett taking a player off the ball.
Robertson cleared his bench with former Southland Stag Pasilio Tosi, John McGlashan College old boy George Bell, Wallace Sititi and Sam Darry became the latest All Blacks. They made an immediate impact, each having a hand in a sixth try for Highlanders prop Ethan de Groot.
Bell then burrowed his way over the chalk to bring down the curtain on a relatively dominant All Blacks performance.
