Politics and rugby haven't been synonymous with each other in recent years and Hames might feel the brunt of that.
Luke Crawford, the Maori All Blacks' team kaumatua, said that while the political statement was Hames' personal choice, the team as a whole did not support individual issues and that Hames might not be able to wear the armband in the future.
"Players obviously draw inspiration and motivation in any number of different ways," Crawford said.
"While some players may support this issue as individuals, it is not part of our kaupapa as a team and team management have reminded players of this."
New Zealand Rugby also has set guidelines around what players can and cannot write on their apparel during matches.
According to NZR General Manager Neil Sorensen, "There's an expectation that staff and players do not involve themselves in conduct that may bring their employer, and the game, into disrepute."
Sport and politics have always been an area of consternation, but to avoid controversy, Hames might be forced to change the words he writes on his armband.
The Maori All Blacks are set to take on Irish club side Munster this Saturday.
