A fire in a flat in Whanganui has left three people injured, with one person's injuries so serious they were taken to Whanganui Hospital for treatment.
St John Ambulance spokesman Mark Tregoweth said the other two people were treated on the scene by ambulance crew for "minor injuries".
Fire services were called to the property on Harrison St around 3.30 this afternoon.
Fire communications shift manager Mike Wanoa said when crews arrived at the scene they saw the flat was "fully involved" in fire.
When they found one person with serious burns and suffering from smoke inhalation they called St John Ambulance.
Five fire crews worked to put out the blaze, which is now under control.
Mr Wanoa said the fire crews are now working in "salvage" mode and that two fire investigators are looking into the cause of the blaze.
The building contains three flats, but only one flat was damaged in the blaze.
