"I said, 'Who does this? Who sees someone come in the door and ask for a cookie?" he said.
"He goes, 'I do'.
"I go, 'you just did'.
"And then one of the other boys looked at me and said, 'I know you'.
"I said, 'no bro, I'm not your father'. I thought they were just kids being silly so I decided to just play along.
"He said, 'no you're on tv'.
"I said, 'nah, bro, you can't get a cookie out of me that way'."
But then the boys started reciting the advertisement.
"He goes, 'you're that fellow on that ad, family violence is okay' - nah, it's not okay'.
"Then the other one remembers I said it's not okay to hit women, and I go 'wow-oh!'
"The first one started reciting back the words. It was just shocking, and I said to him, 'how do you remember me?' And he goes, 'by your hair'.
"I asked the other one and he goes, 'oh, I saw it in this home and that home and that home that I've been to'.
"Then we just sat down, had a wee talk to them about different things. I talked to them a little bit about family violence. I asked them where they all lived. They told me. I took a photo with them.
"And I said, 'you boys have been good to me and you can all get a biscuit'."
Tamati said he did not ask the boy who had lived in multiple homes to give any details of his past. He believed the four boys had gone into Subway to ask the staff for free cookies.
Tamati himself grew up only a few streets away from where all four boys lived in māngere.
"I was just so sad, sad that it's still happening, that the kids who were my age when I was living there are still going through that," he said.
"But I was totally stoked that two of them knew the ads. I get it [recognition] from adults all the time but they can't remember it word for word, but these little kids knew it word for word."
Tamati is a fulltime campaigner and counsellor on family violence with his own non-profit agency Safe man safe family Aotearoa.
