They would bring cans to keep a stock of food up as well as leftover kai they had.
Some students would come to school without lunch every day but wouldn't say anything.
"We just all pitched in ... because we only want what is best for our tamariki" she said.
Now with the support she's noticed the students aren't hungry any more and are able "to have a big kai together so there is no embarrassment".
"It's just like a big picnic to them."
They also encourage the students to take any leftover food home.
KidsCan chief executive Julie Chapman says the back-to-school period is a particularly hard time of year for the 800 schools they support.
Ngarangione said at the kura they allow families to pay weekly or fortnightly what they can, but "work it around them" as she doesn't want families to have added stress.
"Because I know the families, I tell them if you're finding difficulties paying come and let me know and we will go with what you can give.
"Once you communicate, you can see their stress is lifted".
KidsCan is aiming to raise $350,000 to help support families with back-to-school costs.
