His other tattoo is one designed by a nephew who has a background in design. It has ta moko patterns and sits on the inside of his forearm.
Both of his tattoos were inked by friend and fellow actor Gordon Toi Hatfield.
Davis, who hails from Raetihi, near Ohakune, laughs as he talks about the relationship he has with his tattooist.
"He does all my tattoos, but he whinges and moans about it because I don't let him design them. He has a cry about the bloody things, and he's like: 'Oh, when are you going to let me design it'," he laughed.
Davis acknowledged that there was a reason behind getting his tattoos in fairly discreet places - not necessarily to show off that he has tattoos, but for his own knowledge.
"I used to get really annoyed at the whole sleeve thing.
"I think, as a Maori and as a human being, it doesn't really matter. As long as I understand who I am and where I'm from. It's not about identity for me ... it's just about representing that right [to get a tattoo].
"The one on my back has meaning. But the one on my arm - I just make it up every day, when someone asks me."
He is now planning to get more ink done, including one paying tribute to his tribe, Ngati Ruru.
"I want an owl tattooed on my arm because that's one of my tribe - Ngati Ruru, the people of the ruru (owls).
"But my wife doesn't want me to. She thinks that they look scary because they've got yellow eyes."
He is also hoping to one day wear the puhoro - the traditional full-body Maori tattoo covering the abdomen, buttocks and thighs, worn by men.
"I'd like to one day sport one and wear it. That'd be awesome."
