The army recruit who collapsed during a gruelling SAS training exercise is now in a critical condition in Auckland Hospital after his health deteriorated yesterday afternoon.
Lieutenant Alexander Teira Cowan, 25, collapsed while running in the Hunua Ranges near the SAS base in South Auckland on Wednesday last week.
He was considered to be in a critical but stable condition earlier this week.
A hospital spokeswoman said his health had worsened yesterday afternoon and he was now in a critical condition.
Mr Cowan fell ill during an exercise where he and other recruits were required to complete an 8km run in uniform while carrying equipment in a load-carrying vest weighing about 10kg.
