Lomu helped launch the Rugby World Cup last year, but during the tournament was taken to hospital in Auckland, where unconfirmed reports stating that he was having issues with his kidneys.
He was diagnosed with serious kidney disorder nephrotic syndrome in 1995, and underwent his first organ transplant in 2004, and an interview in New Zealand Woman’s Weekly Magazine revealed that the donated kidney – from friend and radio host Grant Kereama – had effectively stopped working.
Lomu has lost 30kg in weight since last September, and has been undergoing dialysis three times per week for 21 hours.
The 63-test wing, who scored 37 tries in a glittering career from 1994 and 2002, said to the magazine they were now looking for a second donor.
"We were hoping to see some improvement but nothing has made any difference, so the next step is to try to find a donor," Lomu said.
Nadene Lomu said the consistent battles with Lomu’s health were taking their toll.
“When trial after trial is smacked in your face, it can be hard. I'm beginning to wonder what else can go wrong,” Jonah’s wife said.
