Laura Strawbridge, his wife, said today the family was thrilled to have raised so much money in such a short time.
"Thank you so very much to all of you kind people who are getting behind this appeal," she said.
The Samoan intensive care unit is headed by Middlemore Hospital physician Dr David Galler, who first treated Mr Strawbridge when he was admitted this week.
In her appeal on the Givealittle website, Mrs Strawbridge has asked people to: "Please help Dr Galler and his 'wonder' ICU team make it much easier to continue their amazing, compassionate work."
The money raised will help to buy medical equipment for the unit including a computer, syringe pumps, an echo machine, airways equipment, a dialysis machine, a vital signs transport monitor, and a portable oximeter.
The family has requested privacy as it remains focussed on Mr Strawbridge's recovery but had promised a further update on his condition this evening.
