He said he never considered being a donor until his brother needed a kidney. "When I got my licence I was like 17 -- you don't think about too much when you are that age."
Mr Tavinor said he'd love to see more done to raise awareness of kidney donation, and to make it easier for those who wanted to donate. He said ideas like a parliamentary member's bill that would vastly increase payments to kidney and liver donors while they recovered seemed a good idea.
The Financial Assistance For Live Organ Donors Bill by Chris Bishop, National list MP based in the Hutt Valley, was drawn from the ballot in June.
While it wouldn't have helped Mr Tavinor, who saved up his holidays for the surgery, he said it might make a difference for others. "I didn't go in this for publicity. I did this to help my brother out."
