The Kohanga Reo National Trust says their doors are open to some Kohanga Reo which have been de-registered for not filing their returns on time.
Charities Services is in the process of deregistering those who have not sent in an annual return for at least two years.
Some 2000 charities were warned last year that if they did not get up to date, they would be de-registered, losing their tax breaks, and the right to call themselves charities.
Four independent Kohanga Reo - separate to the National Trust - have since been de-registered.
The Kohanga Reo National Trust's spokesperson, Derek Fox, said more than 450 kohanga, which is the majority, come under the trust.
He said it may not be as big of a problem compared with other deregistered organisations, as he believed it would be easy for the kohanga to join the national body.
