Two people have been badly burned after a Christchurch fire.
St John spokesman Gerard Campbell says they've transported two men to Christchurch hospital, one of them in critical condition and one in moderate condition.
The fire started at a block of council flats on Innes Roads, Mairehau.
A NZ Fire spokeswoman says they were called to a flat fire on Mairehau's Innes Road around 3.
She says two crews responded.
