"Solutions lie in communities rather than the Government. Obviously there's a place for policy.
"It's important the Government is improving housing affordability. But before changes in social housing really bite, it's up to communities."
Increasingly, businesses were providing equipment, such as sporting equipment, directly to schools, Dr Wills said.
"While it's really tough on families, it's an opportunity for businesses or philanthropists to make a real difference in children's lives.
"Communities are partnering with schools, businesses and NGOs ... All around the country, we've got communities stepping up."
However, Tukituki Labour candidate Anna Lorck said communities were already stretched.
"They [communities] are doing the best they can, but until we have an active Government that is in touch with child poverty, we won't see change.
"I think our community works really hard now ... The Government is out of touch."
To make schooling costs more manageable, Ms Lorck was calling for higher-paying jobs and a reduction in the cost of housing. "Bringing down the cost of housing, that's what Labour's very focused on.
Ms Lorck also said jobs were "the biggest thing holding our region back".
"Until we can get better-paying jobs we'll continue to see this inequality gap getting wider."
