Attempting to implement a professional culture, Maguire's faith in young NRL stars and non-negotiable standards around humility and training ethic have struck an early chord.
Look no further than responses from Joseph Manu, Brandon Smith and young captain Dallin Watene-Zelezniak.
Tapping into personal meaning has been another successful aspect.
"I was very fortunate to watch a number of the Kiwi people after the win against Australia and see the passion they had around that team winning… family members and a number of people doing haka in the grandstands," Maguire said. "That's the stuff I want to make sure we instil."
Maguire also seems to be getting the balance right in managing ethos.
The Kiwis enjoyed their trip north – a two-day stop in Dubai featuring a desert safari with some players adopting full local attire. Bromwich suggesting "Isaac Liu actually looked like a local I thought".
Maguire's trust extended to allowing some of the 24-man squad to visit Dublin on their day off before returning to camp on Saturday afternoon in Wigan.
Back to business, he has been quick to ensure no heads are in the clouds.
"It's only one victory," Maguire said. "We haven't really done anything yet. It's about what you do over a long, long period of time. That's something the team has spoken about and I think is the reason why they've dived straight back into training. We understand what we are heading into.
"I've looked at the team and the dynamics of where we want to go. I'm a big believer in youth. You give a young man an opportunity and they perform and keep performing, well, they can stay there for a long period of time.
"At the international level it's something I suppose the Australian team has had, and the England team have now, is a lot of players who have played a lot of football together.
"Having that over a period of time is something I want to build."
These messages are music to the ears of especially those who have experienced the extreme highs and lows the Kiwis often encompass.
Bromwich, for one, has noticed changes from previous squads.
"I think there is a bit of a different feeling. A lot of the boys are young. I've come into camps before where the boys are older. You look around the team now and there's only really Adam Blair that has been there for a real long time. The young boys have great attitudes. They're all hungry to play, hungry to train, which is very refreshing for me.
"Michael let us savour the moment after the game but as soon as we got over here he let us know that's been and done; we're here for a job, we're here to make our families proud, work hard and play some good football."
Last time out, in the controversial Denver test, Wayne Bennett's England comfortably outclassed a heavily weakened Kiwis 36-18, Maguire's first outing as test coach starting in somewhat predictable fashion.
But with everyone on deck the Kiwis were a different beast against the Kangaroos.
Now they need to prove it was no one off effort.
Bromwich, Jared Waerea-Hargreaves and Kevin Proctor again need to dominate the middle to give their new spine the required time and space to thrive.
While Sam Burgess is missing after wrist surgery, the other two brothers present similar challenges.
Containing Raiders playmaker Josh Hodgson will be another focus, and England should benefit from a host of in-form Super League grand finalists bolstering the squad which dealt to France 44-6 on Wednesday.
But if we take Bromwich at his word, there could be something special brewing in this Kiwis team.
"We played a good brand of football against Australia. We weren't throwing too many offloads that weren't going to the person on the full or anything too crazy. We based our game on building pressure and a good kicking game. If we can do that over here, that'll go a long way to winning the series."
