In an interview with Sportsmail's Oliver Holt before the tournament in August, Lomu talked about his illness, saying he wanted to live to see his sons Brayley, six, and Dhyreille, five, celebrate their 21st birthdays.
'There are no guarantees that will happen, but it's my focus,' he said in the interview. 'It's a milestone that every parent wants to get to. My dad died young and that makes you think.
'I want my boys to be healthy and if they get to 21, they should be fit and healthy and live a normal life.' Despite his illness, Lomu starred at the 1995 World Cup, helping the All Blacks reach the final in which they lost to South Africa.
