An English language school in earthquake-hit Christchurch said Thursday that 48 students and staff, including at least 10 Japanese, were missing after the disaster.
Kings Education, which was based in a building flattened in the 6.3 magnitude tremor, released the names of staff and students on its website, saying the list was compiled with the aid of witnesses and education authorities.
The missing included 10 from the Toyama study group from Japan and five new students who were only in their second day at the school in Christchurch's CTV building when the quake hit.
South Korean students are also known to be among the missing, along with students from many other countries who had travelled to New Zealand's second largest city to learn English.
Most of the missing were listed as "presumed in building", placing them at the CTV site, which police on Wednesday said they did not believe contained any survivors.
It also listed about another 40 students as "status unknown" but did not provide any explanation of what it believed may be their fate.
