But he is still on a ventilator and dialysis. Ms Trodd said he will be in intensive care for a while and his condition is still critical.
Ms Trodd has started a Givealittle page to raise funds so that her 77 year-old mother, Rae Glockling, and her 39-year-old sister can be there to hold his hand.
Ms Trodd said the former Wanganui Boys' College student was known as the "quiet giant" by his high-school peers.
"After he left school he came out of his shell. He was my husband's best man at our wedding and I remember the speech he gave, he said to my husband: 'you couldn't have found a better soulmate'.

"He is such a giving person and I am absolutely devastated but he is a fighter and we will get through this," Ms Trodd said.
Mr Glockling, an Microsoft engineer for a hospital, had been living in London for more than five years.
Before that, he was living and working in Whanganui.
He is now a patient at Harefield Hospital in London, fighting for his life.
Ms Trodd said he is in one of the top two hospitals in the world so in some ironic way he was very lucky.
"The doctors said the medical event was very rare and normally the chance of survival is 10 to 15 per cent but because he is so fit and healthy he is looking at a 30 to 50 per cent chance of survival.
"He has pulled through the first critical 48 hours. He is a fighter and if anyone can make it, he can."
Her mother and sister have borrowed funds and are on their way to London but Ms Trodd said she does not know how long they could be there.
