Mouat, who runs Famous Dave's Tattoo Studio, told ZM's Fletch, Vaughan and Megan he wanted to showcase Bloomfield as a strong character.
An Anzac poppy is featured underneath. The Beehive and the statue of former Prime Minister Richard Seddon are seen in the background.
"It took about four hours to design and tattoo," Mouat said.
"I just had a look through [photos of Bloomfield] and liked the one with the hair flowing in the wind.
"It's great. Very stately."
Sherilyn's tattoo was inked on her calf muscle.

Thank you, Sherilyn, this will go down as definitely one of the most memorable tattoos that I have done.

Mouat said it was the first Covid-related tattoo he's done, but wasn't surprised when Sherilyn came in with the idea.
"I know with Sherilyn she's fun and most of her tattoos reflect her quirky sense of humour.
"She spent lockdown by herself so she went a little stir crazy and Ashley became her highlight of the day.
