Labour is vowing to keep free school lunches in nearly one-thousand schools if it's re-elected.

Government funding had only budgeted for the programme until the end of 2024, but Labour is committing $650 million to continue it.

It says the meals save families $33 per week per child, or more than $1,200 per year per child on average.

Labour's Associate Education spokesperson Jo Luxton spoke with Charlotte Cook.
