The All Blacks are among a number of Kiwi household names sporting white armbands in support of child charity Cure Kids.
The charity, which has a vision to "find cures for kids", has launched a campaign, in partnership with the national team and New Zealand Rugby, to raise awareness around the need to invest in medical research.
"It is about getting New Zealanders to make personal connections between the crucial research that Cure Kids funds and the difference it makes in the lives of the children and young people they know," said the charity.
All Black Ben Smith, 30, said the campaign, called, "everybody knows somebody", provided him with an eye-opening experience as he met some of the children the charity was fighting to help.
"It makes you realise just how much some kids go through."
