Much will depend on who takes over from ex-coach David Kidwell, who had chosen not to reapply for his position after New Zealand's World Cup failure, and whether the new mentor wants immediate success or has an eye on the future.
"I've never made myself not available to represent my country — it's just how passionate I feel about it," Marshall, 33, said.
"I'm just enjoying where I am at the moment and, if it happens, it happens. And if it doesn't, it's all good."
After leading the Tigers to a 5-1 start, Marshall's case to add to his 25 test caps and earn his first New Zealand shirt since 2012 is compelling.
A line had seemingly been struck through his name during the reigns of Kidwell and Stephen Kearney.
After a brief and unsuccessful stint in Super Rugby, Marshall was repeatedly knocked back by Kiwi selectors.
The writing was seemingly on the wall in the 2014 Anzac test when Marshall was overlooked despite an injury crisis resulting in back-rower Tohu Harris filling in at five-eighth.
Asked if he ever felt like he'd been blacklisted, Marshall said: "No. When I talked to them, they made it clear it wasn't personal and that other people were playing better than me.
"That's all you can do is try and be better," he said. "I've had a good start to the season but it can turn pretty quick."
