Flynn is one of five players with All Black experience in the Maori side to face Ireland in Rotorua, along with skipper Liam Messam, fellow flanker Tanerau Latimer, second five-eighth Luke McAlister and winger Hosea Gear.
All will be pushing their claims for a test recall, both in their performances against the Irish and also against England in Napier next Wednesday night.
But Flynn, whose run-in with injuries continued this year with a disrupted Super 14 for the Crusaders, wants to concentrate on his performance for the Maori, saying the rest would take care of itself.
"I wouldn't be playing if I wasn't," he said of whether he retained All Black ambitions.
"But I've been out for much of the season so I'm not expecting too much in those terms. It if comes along, it comes along. If not, I'll keep making my steps."
Flynn said he was just happy to be playing rugby during a part of the year when others weren't.
"If we do our job and do it right, what will be, will be," he said.
"As long as we perform for this team, I'll be happy."
Flynn, 29, made his All Black debut back at the 2003 World Cup, but has played just seven tests.
He spent four years out of the test arena before being chosen for the
2008 Grand Slam tour, only to fracture his arm in the win over Irish side Munster.
During the Super 14 last year, he broke his arm, but he fought back to make the All Blacks' end-of-season tour.
The match at Rotorua International Stadium is the second of three fixtures to mark the centenary of New Zealand Maori rugby.
The first last weekend ended in a 37-31 win over the Barbarians, who were able to put the Maori scrum under some pressure.
"Obviously we weren't together that long before the Barbarians game so we had a fair amount to work on," Flynn said.
"We've had a couple of big sessions and hopefully it will be a little more polished come Friday night."
While Flynn expected Ireland to be direct and physical, he also believed that, unlike the Maori's final opponents - England in Napier next Wednesday - they would look to chance their arm out wide.
"Traditionally they've been strong up front, but they're not a bland team in any way," he said.
"They're not like the English, where they play 10-man rugby. They showed against the All Blacks they can go wide and play a quick and expansive style of footy."
The Irish, who go on to Brisbane for a test against Australia next week, have picked a totally different starting 15 from the one that began the 66-28 defeat to New Zealand last weekend.
Flynn said he wasn't surprised by the Irish selection, given that the tourists would have their eye on their clash with the Wallabies.
"They're obviously looking to rest key players, but it doesn't matter who they put out against us," he said.
"If we go out and grab a win, then it's another scalp for the Maori."
