"I think it's incredible. It's an absolute privilege to be part of that school," she said. "That community is the closest community I've ever been part of.
"You hear so much about people looking out for themselves and not knowing their neighbours.
"Merivale is not like that. I know there are lots of issues but they get past that. They will be caring rather than trying to demonise them. They want to make a difference."
Ms Tinetti, who is an NZEI board member, said her work within the school and community was "give and take".
"I don't expect anything in return for any of what I do but I get a lot on a day-to-day basis, and in the long term.
"Where I see children come back who have stayed in school and gone on to get qualifications and making a difference in their own lives - that's absolutely the reward."
Former students often returned to the school years later.
"It's who we are. It's part of that bigger community. It's not about upping and leaving. We will follow them every step of the way."
Ms Tinetti said the caring culture of the school was a collective effort.
"I think the school has always been like that, even before me.
"That's just the community. It's not about me, it's about the team.
"It's the team that makes a difference. I'm just the leader."
Ms Tinetti is on leave studying at the University of Canterbury for a Master's on the Positive Behaviour for Learning programme, which the school introduced in 2013.
