A lobby group for writers is urging the Government to save the company that provides the School Journal to primary schools.
Learning Media is a State-owned enterprise which has been publishing the journal and other material for the Ministry of Education for 20 years.
It now faces an uncertain future after the ministry ended its preferred supplier contract, forcing it to compete with other publishers.
The New Zealand Author's Society has written to the ministry asking it to reinstate Learning Media as the sole preferred supplier.
Executive director Maggie Tarver said that if the Government insists on competition, it has to guarantee that domestic rather than overseas writers will still be used.
