Spark is offering entry level home broadband for $15, a quarter of the usual price - but only to some families.
The telecommunications company is offering heavily subsidised broadband to families with school-aged children that cannot afford commercial home broadband services.
Spark chief executive Simon Moutter said the programme for social change, Spark Jump, would give access to thousands of children.
"Digital inequality, especially when it comes to online learning, is a significant challenge for New Zealand," Moutter said.
"Every day, tens of thousands of children do not have access to home broadband and come home from school unable to continue their online learning."
