Labour would introduce a minimum qualification requirement for all early childhood educators, seeking to curb the rapid growth of taxpayer-subsidised nannies and au pairs.
The party's education spokesman Chris Hipkins says early childhood funding should be focused on boosting participation in quality, free services, and ensuring value for money.
"Instead it is going on subsidies towards nannies and au pairs for those who can afford to make that choice, while children from low-income families still top the statistics for non-participation," he said.
"Surely the Government should be just as focused on ensuring that services are delivering quality as they are on increasing bums on seats."
Mr Hipkins' comments follow a Herald report from the weekend which revealed rapid growth in the home-based sector, with a record number of children - 25,000 - now in government-subsidised services which don't require educators to have have any qualifications.
