The Ministry of Education says they have dealt swiftly with incidents that have involved serious harm to children.
Cases of rough handling, inadequate supervision and children going unfed have surfaced in a horrific catalogue of complaints against early childhood education services.
Ministry spokeswoman Katrina Casey told Chris Lynch they are investigating more complains this year.
"In some cases, individuals in those organisations have been charged, and also we have taken action to make sure that anybody who hurt a child in an early learning setting, does not return to that setting."
The Early Childhood Education Council says it's heartening to see the complaints process against the industry is working.
Council spokesman Peter Reynolds told Chris Lynch over the last few years complaints have been about the same level or slightly less.
He says six per cent is a pretty low threshold.
"Never the less, we don't accept things that aren't right and they need to be sorted out. Services that should be supported should be supported, and those that shouldn't be operating in our sector need to go."
