Two Christchurch secondary schools have been told they can reopen on their earthquake-damaged sites, but may have to move again in two years.
Avonside Girls' High School and Shirley Boys' High School have been sharing a site with other secondary schools since the devastating quake on 22 February.
Education Minister Anne Tolley says the Canterbury Earthquake Recovery Authority has agreed to the sites being used again - but only for two years, as the schools' land needs further checking and families in catchment areas might move away.
Mrs Tolley says reopening the schools on their sites temporarily could cost up to $10 million.
Shirley Boys' is expected to reopen next term and Avonside Girls' next year.
