Almost 70 schools in Northland have signed so far to take part in Fonterra's milk for schools programme.
The pilot programme has been launched as part of Fonterra's aim to make milk more affordable and accessible.
It will start providing milk in 250mm packs to Northland school children from next month.
Schools in the region have until the end of the month to register.
Fonterra says it will use the pilot scheme to iron out practical details such as delivering the milk, keeping it cool and recycling the packaging before taking the programme nationwide.
