Ross Mulholland, who accidentally amputated a finger and thumb, is a "model patient" who has done everything possible to give the reattached digits the best chances of recovery.
Mr Mulholland, of Helensville, north-west of metropolitan Auckland, chopped off the index finger and thumb of his left hand in a wood-splitting machine in November 2010.
The severed digits travelled in a chilly-bin to Middlemore Hospital, where they were reattached. A team headed by plastic and reconstructive surgeon Stanley Loo spent 14 hours in two operations reconnecting the bones, nerves, blood vessels, tendons and skin.
Now, more than a year after surgery, Mr Mulholland, 62, said his digits had recovered so well they could do 70 per cent of the things he wanted them to.
