One of the biggest athletes to ever muscle his way on to the rugby field is preparing to tackle international poverty by downsizing his diet.
All Blacks legend Jonah Lomu, 1.96m tall and at one time weighing in at 125kg, was believed to be worth in excess of $15 million at his peak.
But for five days in September, to raise awareness for UNICEF's Live Below the Line challenge, the big man and his family will live off just $2.25 a day each.
That small figure - less than the price of a McDonald's cheeseburger - is the New Zealand equivalent of the extreme poverty line.
''Five days of living on $2.25 a day is going to be tough, but that's what life is like every day for 1.4 billion people around the world,'' Lomu said.
"Even in our Pacific backyard up to 40 per cent of children haven't grown at the right rate because of malnutrition. I want to help... lower these numbers.''
Lomu's has been tasked with coaching those who sign up to the challenge, but he said that wouldn't be enough. Putting aside his personal health battle, he wanted to join in.
''I decided it wasn't enough to just be [the] coach. My family and I need to experience this. So, having checked in with my doctor that it's OK to do the challenge I'm now busy planning how my family can get the most from our budget.''
Nadene Lomu said her husband's illness would not stop his involvement.
''Although Jonah's health is not 100 per cent, he's doing well and it's about being sensible with choice.
''Jonah and I decided it's important for us to show our support fully and as a family to experience for the short time of just how tough the struggles are for the children in [poverty].''
UNICEF New Zealand executive director Dennis McKinlay, who recently returned from the Solomon Islands, said Pacific poverty was a big problem.
"Good nutrition for children is as critical as clean water, but one in four households in the Pacific Islands don't have enough money for food [and] 30 per cent of children in the Solomon Islands are suffering from stunted growth because they are malnourished.''
Live Below the Line is organised by Global Poverty Project and runs in the US, UK and Australia. In New Zealand in 2011 the campaign raised $120,000.
