This was Luatua's 25th game for Auckland, but the first since 2012.
"It felt good to be back in the blue and white hoops, and good to be wearing my [MAG] school socks," he added.
Though he was unsure where that left him in the All Black frame, it is likely that Liam Messam will again get the nod, despite his handling lapses against the Wallabies at Eden Park, while Jerome Kaino will not be back on deck until next month.
With his Auckland teammates Charlie Faumuina and Charles Piutau, Luatua flew into Napier and Shield Fever yesterday morning and straight into full training.
"I was thinking about that the other night when [Blues teammate] Brendon O'Connor and his boys took the Ranfurly Shield, so to have that and the All Blacks at the same time and the same place should be pretty special."
Auckland coach Paul Feeney loved having his three All Blacks for the full week, and he is likely to get Piutau, who had a mixed game, back later in the week. Faumuina, too, needs to lift his game, as he was not able to dominate the raw Tasman loosehead Siua Halanukonuka at scrum time. Luatua was the best of the trio.
"He had an up-and-down with that kick in the corner, but redeemed himself by scoring. It was good having the All Blacks back, and all three of them added to the team. They also gave our boys confidence, so I'm pleased with their efforts," said Feeney.
He waits to hear from All Black manager Darren Shand - probably by today - whether Piutau will return for the Wellington clash on Saturday.
"We certainly don't count on having him, but if we do, it's a bonus."
