A Christchurch man who travelled to Scotland to donate a kidney to his ill sister never gave it a second thought - even after the February earthquake forced his family from their home.
Anaesthetist Duncan Williams, 51, is humble about the huge gift he gave his sister, mother of two Lesley Ross, who was facing renal failure and dialysis caused by polycystic kidney disease.
"Duncan right from the start said 'I will do it'. He didn't think twice, because it was his sister," his wife, Ruth Williams, told the Herald.
Dr Ross, 49, a paediatric consultant in Edinburgh, said there were no words to express her gratitude.
"My brother's home was hit by an earthquake around the same time I needed the transplant and, despite not having anywhere for his wife and baby to live, he did not hesitate to come to Scotland for the planning meetings and then surgery," Dr Ross told Scottish newspaper the Daily Record.
