A New Zealand Army soldier suffered serious injuries this morning during the disposal of a flare.
A New Zealand Defence Force (NZDF) spokesperson said the incident occurred at the Glentunnel demolitions range.
The corporal is a member of the NZDF Explosive Ordnance Disposal team. Both he and his family are being supported by the New Zealand Army.
A St John spokesman said the male patient in his 20s was flown to Christchurch Hospital by helicopter following the incident around 10am.
"The New Zealand Army takes its health and safety responsibilities seriously and an investigation into the incident will be launched," the NZDF spokesperson said.
