The Ministry of Education has confirmed it's taking legal action against a number of wall cladding manufacturers over the 1.5 billion dollars worth of leaky building repairs at schools.
The move has prompted building products company James Hardie to halt share trading in Australia.
Acting Secretary for Education Peter Hughes says the Ministry has lodged a High Court claim on behalf of schools in order to protect Crown assets, off-set costs and promote better building practises in the future.
He says repair work is currently underway in more than 800 buildings located at over 300 schools across the country.
The Ministry of Education won't be making further comment now the matter is before the courts.
Earlier, Minister of Education Hekia Parata would not confirm if the case is linked to leaky building syndrome.
She said she does not have the information needed to give accurate responses.
