Marshall expressed his desire last week to reclaim a Kiwis jumper in the Four Nations and caught up with Kiwis coach Stephen Kearney last weekend.
"Hopefully that leads to being selected but if it doesn't, it's not the end of the world for me," he said.
"I grew up dreaming of that and I've had the opportunity to do it and hopefully I get to do it again. Representing your country is the highest honour in the game and if it comes my way, I'll take it."
There are a number of reasons why Marshall should be seriously considered. He's still only 29, is playing well for his club, is an experienced international with 27 tests - including 19 as captain - and is a match-winner.
New Zealand don't have great depth in the halves and at hooker, evidenced by the fact Harris played at five-eighth and Ben Henry slotted into hooker in the absence of Issac Luke and Leuluai.
But there are also risks with Marshall. He's a big personality and Kearney made no secret of the fact he wanted a new culture within the Kiwis after it emerged some members of the squad indulged in sleeping pills and energy drinks during the World Cup.
It won't help Marshall's cause that his Dragons side won't be involved in the playoffs. Players whose teams are involved are often at an advantage because they are match fit.
Penrith's Elijah Taylor (knee) and Warriors utility Ben Henry, who needs a knee operation, are the only players so far ruled out of contention but that number is likely to increase as others require off-season surgery.
