The former Crusaders prop, who played 61 times for the franchise, said his loyalties now lay with Irish rugby but he was excited to be back in New Zealand.
"I've been with this team a while now and with Leinster so I've got to know the boys pretty well so I feel more part of it now than ever and the connection is probably with these guys now."
Feek said the challenge of the three-test series against the All Blacks didn't have to be a daunting one.
"To go up against [Tony] Woodcock who has 83 tests and Horey [Andrew Hore] and those guys is a great challenge. Woodcock is potentially one of the best looseheads in the world at the moment and coming up against Owen Franks, the boys know all about him."
Although some of the Irish players had come off a long club season plus a Six Nations tournament, in which the national team struggled, Leinster fullback Rob Kearney said it was important the mental approach was right from the start.
"It's a three-test tour against the world champs and if you don't switch on mentally it can be a long three weeks where results won't go your way," he said.
"You're representing your country playing against the All Blacks in their own backyard. As a professional player if you can't get yourself fired up for that thought alone then you're probably in the wrong game."
Playing at a venue in which they enjoyed a famous World Cup victory over Australia would help, he said.
"We have really strong memories of Eden Park. We all stepped up and played really well. That has to count for something, even if we were playing another team.
"It was a huge occasion for us to turn over Australia in a World Cup... we set a bar there in that game, a standard, and it's important for us to keep matching it."
