Robbie Ritchie never imagined he could raise enough money for an expensive lifesaving surgery in just six weeks.
The 33-year-old is surprised and humbled by the generosity of the New Zealand public who have donated or raised $215,000.
Mr Ritchie is flying to Germany today with his wife Jacqui for surgery on his brain, to be performed by a leading doctor.
He has an abnormal collection of blood vessels, known as arteriovenous malformation, and has an 80 per cent chance of a haemorrhage. That chance grows by 4 per cent every year.
