"Two thousand people ended up there on the day. We took [the kids] to parliament, they got up, they spoke. The mamae that came out that day was just absolutely heartbreaking," she says.
"The past six months, it's really snowballed. I'm getting as many as four children in one night messaging me. It needs to be addressed more now."
Marsh says she feels "very privileged" to be trusted by the rangatahi that come to her for help to deal with their problems, being that she's someone they don't know personally.
'The door is always open'
"A lot of them can't quite verbalise what's going on. Your mind is like a cloud and you know you need help. So when they trust and come to me, some of them are cutting, and some of them are suicidal. Some of them just need an ear.
"I think a lot of it is when they see me, they see a lot of themselves. The door is always open and it's non-judgmental."
Helping rangatahi has definitely taken its toll on her too, with Marsh saying that "some of the weight is really heavy". But she continues to help where she can.
"If we look at it existentially as Māori, all those kids are all of our kids. We are parents, aunties, nans to all of these kids."
