A Christchurch person has suffered chemical burns after an incident at a gelatine plant.
Emergency Services were called to the Gelita factory in Woolston just after 2pm.
Fire and Emergency say they're still on the scene dealing with a chemical spill.
A spokesperson says it's still not clear yet what size it is or how it happened.
A St John spokesman says one person was taken to Christchurch Hospital in a serious condition.
Gelita has suffered issues with chemical leaks before - with a large part of the plant burning down early last year after a spill.
