The group is funded by grants from charitable trusts and donations and receives no public funding.
It provides research about the causes and effects of poverty on children and their families, and informs the public, policy makers, media and politicians of policy changes needed to reduce child poverty.
The group's executive member for Western Bay of Plenty, Alan Johnson, said while child poverty could be eliminated completely in a country like New Zealand, too many children didn't have the basics.
"We are building a group of people here to advocate for children's rights and child poverty in the Western Bay," Johnson said.
Well-organised direct activism could make a difference, he said, describing a protest in Auckland where 1000 people arrived to sleep in their cars to protest the lack of housing.
"Because of the demographic and relative wealth here, children's issues are often overlooked, but we have unidentified poverty in this area. It's one of the most serious issues facing New Zealand.
"For us it's about public discourse. We need to have the interests and concerns of children locally talked about."
The group will meet again in December to plan the organisation's first project for the Bay of Plenty.
